Broken Flaperon Repair

We just repaired our proto aluminum airplane.  We put triplers on the root flaperon riser, and we put a doubler on the opposite end flaperon riser.  We did this on both flaperons, left and right.

The doublers were reinforced with JB Weld (cleaned and roughed surfaces first) and the extra new pin bolt is a stainless 6-32 bolt with a locknut.

In the second photo, you can faintly see the crack on the original flaperon riser.

Here's the pics:


The original failed part is in the middle of the aluminum sandwich, above.

6-32 stainless bolt with washer.

Right wing riser with reinforcements.  This one wasn't cracked.

Outboard flaperon riser with doubler.  We reinforced both outboard left and right flaperon risers.

Inboard flaperon riser with triplers, JB Weld, and bolt (which will be trimmed).

Service Bulletin: Broken Flaperon Riser

As Belite manufactures Part 103 aircraft, and also parts for experimental (customer-built) aircraft, this bulletin has no force of law.  You may choose to follow our advice, or ignore it.  We hope you follow our advice. A picture of the broken part, along with a new part is at the bottom of this post.

While inspecting our prototype aluminum airplane, one of our personnel found a broken aluminum flaperon riser on the innermost position on the flaperon.  (The position closest to the fuselage, or root of the wing, where the flaperon connects to the control cable).  Further examination determined that this was a fatigue failure.  This failure appears to have been possible where ever this part was used, and we have been using this part for some time in our entire line of aircraft.  We do not know when this failure occurred.

We have sold aircraft and kit parts with these flaperon risers.  Some were made of steel, some were made of aluminum.  We do not know which customers have steel or aluminum.

If your part is made of steel, you may ignore this directive.  We believe the steel parts are OK.

If your part is made of aluminum, we recommend that you immediately install a reinforcement before further flight.  We are in the process of designing an improved part, and also designing a reinforcement plate for existing installations.  We expect this redesign to be completed by the end of next week.  We expect replacement parts and reinforcements to be available sometime soon thereafter.

Please contact us if you believe you have affected parts, so we can advise you when reinforcement straps are available.

In the future, we will be creating a place for service bulletins on our main website.

Fear and Loathing in Northrock Business Park

It was close to lunch time, and I opened the door to my office ---

And saw a collection of people down the hallway, just outside of Senator Jerry Moran's office.  (The Senator and I are office neighbors.  One thin wall separates his staff personnel from my office/lab.

What?!

I heard passionate words; a variety of voices, and I noticed the head staffer standing in the hallway, listening patiently to a mixture of anger, confusion, persuasion, and distrust. 

45 minutes later, they were gone. 

It's early in the campaign season; I'm sure there will be more.





Random Observations:

1.  Why am I next to a Senator's office?  (A:  It's actually a great place to be.)

2.  Who was this group?  (A:  I'm pretty sure it was moveon.org)

3.  What does this have to with ultralight airplanes?  (A:  not much.)

4.  What does this have to do with "Fear and Loathing" (Hunter S. Thompson's famous novels/movie)? 
(A: Well, I was handed a button which said, simply, "Dream".  In some sense, "Fear and Loathing (the novel) was about a pursuit of the American dream.  And then there's "Fear and Loathing on the Campaign Trail", also by Thompson.  Seemed like some convenient parallels.)

Fascination of flying like a bird

I've never just posted a link before.

But today, I make an exception.

Here is a video of a model airplane which flies *exactly* like a real bird.

Best Aircraft at Oshksoh 2011

Long time readers are aware of my interest and experimentation in electric aircraft.  Here's the first one I've seen that appeals to me.  It had reasonable performance, length of flight, and simplicity.

My attempts to fly the Belite with electrics have produced a very good, very short flight.  I'd shelved the project until I had some inspiration worth working on.

I learned a lot from this plane.  Got my inspiration back.

James Wiebe named "August Raspet" EAA award winner for 2011

Hi Friends,

I've got big news.

A few weeks ago I received a letter from Rod Hightower.  He is the president of the EAA -- and the EAA is the most important voice in experimental aviation in this country.

I was informed that I had been selected for this year's "August Raspet" award, which is given annually.  Quoting the EAA:

"Since 1960, the Dr. August Raspet Memorial Award has been presented every year to a person who has made an outstanding contribution to the advancement of light aircraft design."

They cited three reasons for awarding this to me:

1)  My work in developing carbon fiber in ultralight aircraft;
2)  My work in developing lightweight instrumentation for aircraft;
3)  And my work in developing "water in fuel" technology for aircraft.

I was mildly stunned by this news...

Anyway, this evening, they have posted the news story on their website:

http://www.airventure.org/news/2011/110727_raspet.html

And tomorrow night (Thursday) I receive the award.

Kind Regards,

James (For my latest news, I suggest you follow me on Twitter:  @jamespwiebe  @beliteaircraft )

New Ultralight Airplane promotionally priced for $14,500

Too much to report to you.!

It's Oshkosh week, and Belite has *lots* of news throughout the week.  We'll take our news one chunk at a time; let's start this post with our aluminum ultralight aircraft.

We posted a great video of our new aluminum airplane flying.  We have the prototype of this aircraft at Oshkosh this week, so please come by our booth and see it.

You can see the video of the aluminum ultralight aircraft here on youtube.  We demonstrated it with a 45HP engine, but we will be selling it with our 28HP engine (expect great performance) and also the 50HP twin Hirth (expect unmatched performance).

Prices on this airplane start at $16,500, Ready To Fly.  (Our Oshkosh special promotional price is $14,500, but YOU MUST place a completed order with deposit postmarked by the end of August.)

This aircraft incorporates a bigger wing and a better tail design (compared with older Belites).  Also, in base configuration, it is UK SSDR compliant!

This airplane, in kit form, sans engine/prop/instruments/fuel tank, is $6800.

An Aluminum Dream

(There is news far below of a new aluminum version of our plane.  Read down...)

***

I've had a dream.  In it, I'm able to take a simple board, lay it across my chest, and in a few steps I am flying.  Somehow, I lay on the board, and it generates enough lift to take me above trees, mountains, streams, and beautiful things.

I do not understand how this can be.  I am not Jetman, but I know that it is real, and in my dream, I am gliding down over a descending landscape.

I am able to breeze by trees, houses, birds, and under a clear, blue sky, I am able to select a landing spot.  In my dream, I land just a few minutes after I take off.  Sometimes, I have a passenger nearby (I do not understand this either.)  But mostly, I am free, and I simply fly.

I feel the joy, and I am determined to share it with others.  I see that as a role given to me:  to spread the joy and the ability to fly above and observe above and be above.  To be above.  To fly.

***

Two days ago, I was down in Tulsa, Oklahoma, making some simple wiring fixes to a plane we'd delivered to a new Belite owner.  The airstrip was overkill long at 1320 feet; there were horses on either side, and the hangar was in the back yard of the house.  Ironically, a windsock was 3/4ths of the way down the strip, and it was positioned nearly in the middle of the runway.  I asked the owner if I could once again fly the plane that was formerly mine, and he said, of course, 'yes'. 

Once around the pattern, a low approach. 

Another time around the pattern.  A hot day.  But 300 feet above the ground, things were comfortable in the open cockpit.

A second time around with a lineup to final approach.  A good breeze out of the east.  A crossing landing on the runway, drifting from left side to right side, making advantage of the crosswind.

Landing.  Barely disturbed the grass blades -- a combination of luck, maybe some skill, some springy gear, and some big fat tires.

Out of the plane.  My wife took my picture, as did one of the new owners.  The other owner showed up late, I started the engine just so he could see it easily start.

***

He called me earlier today, and I answered.  I am in West Virginia, getting ready to deliver a series of talks on computer forensics at Marshall University.  He wanted to know how to adjust the tension on the throttle lever; and I gave him some quick advice.  He'd flown the bird, rechristened 'Queen Lady', and he was tiring of readjusting power continuously.  Surely, an understandable aggravation.  But he'd flown around for 30 minutes, and I was pleased for him.

***

Two planes sold in 24 hours -- that's news.  One heading to California, the other to Missouri.  We cut the prices on some of our planes in order to reduce inventory, and in order to prepare a way for a new aluminum variant.

***

I've always been in love with technology.  I enjoyed putting carbon fiber spars on ultralights -- I thought the strength / weight thing was simply amazing.  I ignored the economics -- figured people would pay.  A few did.  Not many.

***

Kathy and I put out a pricing survey on our planes.  It seems these are the most important things to many of our potential customers:

a)  They like our plane.
b)  They want to fly.
c)  They want to afford our plane.
d)  They may weigh a little too much -- but they still want to fly.  Do we have a plane that will accommodate them?

***

Belite has been in development of an aluminum fuselage of our plane.  An original prototoype was built, and we did a series of tests on it: 

a)  Engine mount strength
b)  Pilot seat strength
c)  Airframe strength -- taxiing  (super hard jolts while going up and down the runway without shocks).

Engine Mount Strength -- over 400 pounds of steel.  Ken needs to smile.

Pilot Seat test -- 819 pounds of steel and sand
Well, I broke the plane while doing initial taxi and flight test.

So we redesigned the cabin area, and a bunch of the round tubing was replaced with square tubing -- much stronger.  It ended up looking like this:

Closeup of square aluminum tubing

So here's a photo of an aluminum airplane.  Notice the heavy cockpit structure, also the monocoque aluminum skin on the sides, (carrying landing loads).  The landing gear is chromaloy steel, and the engine mount is also chromaloy steel.  The aerodynamics are largely undisturbed from our sweet flying, original 254.

Aluminum Fuselage Ultralight Airplane from Belite Aircraft


***

Pricing to be announced at Oshkosh on these models:

a)  Aluminum Belite 254 taildragger with 28HP engine.  Weighs about 210 pounds.  UK SSDR compatible as well!
b)  Aluminum Belite 254 Trike with 28HP engine.  Weighs about 220 pounds.  UK SSDR compatible as well!
c)  taildragger with 45HP engine.  Weighs less than 254 pounds.  Phenomenal takeoff performance.
d)  same thing in Trike.
e)  deluxe taildragger with 50HP engine, carbon fiber, 'chute, every option we make. 
f)   deluxe trike with 50HP engine.

And yes, we're still working in the 4 stroke engine.  And the aluminum kit version.

***

Many of our potential customers are concerned about their weight in relationship to our planes.  These new aluminum planes solve that problem. 

The 45HP engine, in combination with the lightweight aluminum fuselage, provides the ability to lift a lot of load!  We can now handle pilot loads up to 275 pounds in the taildragger configuration.  With really great performance!

***

The aluminum fuselage airplane pictured above has already been presold to a customer.

***

We have two more fuselages already started.  We will have at least one aluminum ultralight at Oshkosh.   Please come see us.

Belite Ultralight Aircraft @ Mythbusters

(c) all photos by James Wiebe, Reproduction prohibited without written permission

If you read all the way to the bottom, I'm posting some more great photos of working at Mythbusters, including some photos of the MythBuster gang and a Belite Ultralight Aircraft.  If fact, the airplane pictured far below is the same aircraft which won "Best Commercial Ultralight" at Sun N Fun -- refinished with a different engine and as a showstopping taildragger....  But first, some of the editorial on what it was like:

ARRIVING MYTHBUSTERS STUDIO, AKA 'M7'. 

No, I'm not shouting, I'm just in shock.

I'd been given the address to drive to by the Associate Producer, a very nice guy by the name of Eric Haven.  I really didn't know what to expect, other than the Google Map streetview had provided a grainy photo of an industrial area near the city's downtown.

I drove into the parking lot, and passed business unit after unit, waiting to find the one that said "MythBusters" on the door.  I realized that nothing said MB on the door, but that the contents of the parking lot had somehow shifted from average cars to a collection of strangeness:  a vehicle which looked like a small desert tank in progress; a bomb bunker, large markings on the parking lot (like a bomb drop "X"), and an oddly painted VW beetle.

I realized I had found Mythbusters.  Kewl.  In the door I went.

Which I did -- went in the door, expecting amazing offices and greatness, and I walked instead into a common room with desks crammed together, a huge mess on all of the walls, a small black dog, and people who were very busy.  And a Mythbuster host or two at their desks, working (or playing) right in the midst of the chaos.  And a big warehouse in the next room, where all the non-location shots would be setup and filmed.

Debris of a hundred episodes spread throughout all the walls, floors, ceilings, parking lots, desks, bathrooms, storage cabinets, and vehicles.

Hey, I can't tell you what we did.   I've signed a blood enabled non-disclosure oath.  But I can tell you some other things:

1)  Our myth will certainly use a Belite airplane.

2)  I've never been a part of a work environment that was so ad hoc on the back end.  What a riot!

3)  The hosts (Tory, Grant, Kari) are fun, witty both on and off camera.

4)  The hosts (Tory, Grant, Kari) can be serious, can show concern and compassion just like all good human beings.

5)  The hosts (Tory, Grant, Kari) really do everything you see them doing on the show.  And they do a lot more.  They are working the myths with great diligence.

6)  There are other people who are also working just as hard to make sure that the show is great TV.  I've mentioned Eric, but there's also John, Lauren, Benny, Amid, Duncan, and many more.

7)  Not that I've had great opportunity to, but I've never seen a group that knew so much about how to get a great camera shot.  Both first and second camera (Ben and Duncan) know their stuff forwards and backwards.

8)  MB very graciously allowed one of my daughters to join the fun for a day.  Duncan (2nd camera) even more graciously took her and put her to work, instructing her on building a super cool show prop (which she did) and having her directly assist with setup on a "Mythbusters" logo shot, which they do frequently and freshly for each episode.  I even got to contribute some thoughts to that particular logo shoot.  It took them 3 hours to produce less than 2 seconds of video.  The end result was world class super hi-def slow-mo footage shot on an amazing hi speed camera.

9)  For all of the fun on camera, there are people who are sweating details.  The producers and the director have plates full when the project is on -- there are loads of unforeseen things (EG:  no porta-potty on location -- where to Pee? -- find a porta-potty).  Some of the unforeseen things cause the director to think on their feet; some of them cause the producer to think on their feet; some of the problems cause the hosts to think on their feet.

10)  It's teamwork.  You have to work very hard to make great TV.

Duncan *WANTS* this airplane.

Some Mythbusters on the (closed) runway.  Notice there's nothing around:  miles from people.

Kari Byron, 'nuff said.

Aluminum CNC parts in Belite's Ultralight Aircraft

Hi!

As I mentioned in the prior post, we are working hard to raise 'production values' of our aircraft out of the realm of old fashioned ultralights.

We've just added CNC aluminum parts as a standard part of our kit ultralight aircraft.  (You can buy our nearly complete kit aircraft, with a welded chromalloy steel fuselage, for $8000, which includes all of the parts pictured below, and much much more....). 

All of our aluminum parts are delivered straight from the CNC machine, still 'in tabs' (the part is still connected via tabs in the billet aluminum it was cut from).  You need to cut the parts out of the billet with a bandsaw and deburr them with a sander, or scotchbrite or a steel brush or a deburring machine.  You also need to drill final holes.  We do this to save machining time, and it allows us to sell these parts at ridiculously low prices.  

Here's pics of most of the parts, along with comparison weights:

Elevator Torque Reverser  -- $35


The elevator torque reverser weighs 3.6 ounces in steel and 4.7 ounces in aluminum.  The aluminum is a solid piece.

Flaperon Idler Bellcrank -- $40 
The flaperon bellcrank weighs 3.4 ounces in steel and 3.1 ounces in aluminum.  You receive it in two parts.  In addition to cutting, drilling and deburring the aluminum, you'll need to hit it with a few beads of TIG weld to guarantee the two parts will stay together.

Heel Brake -- $30 each.

The heel brakes weigh 2.6 ounces in steel and 3.0 ounces in aluminum.  You need two per airplane.  The brake cable attaches to the arm on the left side of the part.  Just flip it around and it is now a right brake.  Both sides of the part are CNC machined out to reduce weight.

Jury Strut attachment fitting -- $35   


There are four of these included with each wing kit.  Each is attached using six rivets to the aluminum spar.  The aluminum version weighs just 1.0 ounce!  We don't know what the original steel ones weigh, we haven't had any in a year or two.  We've always used aluminum.  They are sized to fit a 2.5" OD tube.  You can order them individually for just $35 each.

Big Honking Lift Strut Attachment Fitting -- $100 each
This is a Big Honking Lift Strut Attachment Fitting.  It weighs 6.5 ounces.  We haven't had the steel ones in an eternity, so I don't know what they weigh.  It attaches to the aluminum spar with a row of rivets down each side.  We are currently redesigning this part so that the rivet holes are pre-marked for drilling.  Our wing kits include 4 of these.  Designed to fit around a 2.5" OD spar.  If you are building a one-off ultralight aircraft, maybe you want a set of 4 as well.

Aluminum Pivot in Steel Control Stick Assembly -- Pivot is $35
 Unfortunately, the only aluminum pivot I had today was already installed in an airplane.  So I didn't get to weigh it.  It probably weighs about 3.0 ounces.  The steel version that it replaces weighs 2.4 ounces.

The above picture also shows an old fashioned control assembly (steel structure part).  We still are selling these fairly complex steel parts for $250 each, and one is included in our aircraft kits.  We have developed an aluminum version, but aren't ready to sell it yet.  FWIW, the steel version which we are still selling weighs 6.6 ounces.

Elevator Torque Reverser installed in aircraft.

Rudder Pedal -- $40
 Each of our kits contains two rudder pedals.  The old steel parts weighed 4.0 ounces, while the new aluminum ones are slightly heavier, at 5.8 ounces apiece.

Y Lift Strut Attachment
The old steel part weighed about a pound (very heavy), while the new aluminum part weighs just 6.5 ounces!

That concludes my aluminum CNC part roundup.

More on Belite's Ultralight Aircraft Kit Pricing

My musings on our new Belite Ultralight Aircraft pricing a couple of days ago might be a little complicated to understand.  Here's what it boils down to:

Kit price is now $8000.  Wing kit is $1000 for two complete wings. Fuselage is $4000.  Everything else is $3000.  Total -- $8000. 

This includes a fully welded 4130 steel fuselage, along with a large number of newly designed aluminum CNC machined parts.  We're moving away (rapidly) from yesterday's old-fashioned 'ultralight aircraft', by providing an easily built design which emulates a larger aircraft in just about every manner possible.   And now, with our large amount of aluminum parts, our planes have production values which match far more expensive airplanes.

If you can weld, the tack welded price is just $6800.  As a result, a little used engine scrounging will get you a great brand new flying airplane for less than $10K. 

I got an interesting call from a potential customer who wanted to know if they could adapt our wing design to an older ultralight design.  This was based on their observations of what they discovered by looking inside their wing.  Our wing design locks the ribs around the spars -- it makes perfect sense and is easy to assemble.

New Value in Part 103 Ultralight Aircraft from Belite!

About six weeks, Kathy and I put out a survey to our email list base.  We asked our potential customers many questions, mostly about our pricing strategies for our kits and our finished aircraft.  We received well over 200 responses, and the compiled statistics were loud and clear:  While many factors are important in the purchase of an airplane, the predominant problem slowing people from making a purchase decision is pricing.  Our kits always cost too much.
Kathy and I heard you loud and clear!  We are cutting the price of our kits.

In order to cut costs, we had to make investments in capital equipment.  Fortunately, we recently acquired a new 4 axis CNC machine and a new 3 axis CNC router.  These allowed us to re-engineer many of our parts to take advantage of lower cost, in house production.  Also, eliminating welding time was a substantial part of the puzzle in reducing costs.  In order to eliminate welding time, we had to re-engineer the flaperons and many of the moving parts.

As a result, the new price of a Belite kit is $8000.  (!)  This is a full featured kit, with lots of stuff included.  And if you want to save even more, read all the way to the bottom of this post, and I'll explain how to save another $1200.

While reducing the price, we've also added substantial value.

Here's the scoop:

1) Numerous moving parts (linkages, bellcranks, etc.) which used to be made out of welded steel are now made on our new CNC machine, out of billet aluminum.  As a result, our finished airplanes now look more professional.

2) The pricing includes a fully welded 4130 steel fuselage.

3)  The pricing does not include crating ($700) or shipping.  We've now had shipping quotes all over the US, so we are pretty good at guessing the cost of shipping.  Shipping should run about $1000 to far away destinations (LA, for instance).    So the cost of the kit, including crating and shipping, is now about $9700, fully featured and delivered to your garage.

4)  We've been working on the manual.  While not perfect, it has improved considerably.  Also, the manual and documentation package is now available separately for purchase.  ($80 -- includes manual, some blueprints, lots of stuff.)

5)  We've also now prepared pricing for subgroups.  I'll make posts over the next few days digging into some of these subgroups, but I'm posting a lot of information on each group lower in this post.  Read on...

6)  Flaperons and tail feathers are now much easier to build -- having been redesigned to use inexpensive wooden ribs (cut on our brand new CNC ShopBot).  (Versus our older welded or aluminum / bonded flaperons.)  And weight is slightly reduced!

7)  A very small amount of welding is required on the landing gear.

8)  The tricycle gear kit is now available as a separate option.  It is a comprehensive conversion kit which includes everything necessary to convert a tail dragger to a trike gear plane.  It also has a lower price.  ($400).   A small amount of welding is required.  Includes machined parts for the nose gear assembly.

9)  Here's a rundown on subgroup prices:

  Rudder Kit -- $80 -- includes 4130 steel vertical spar with tack welded hinge points and tack welded tabs; wooden ribs.  Finish welding required:  <1 hour.  Assembles on flat table.  First ship of this new Rudder Kit is end of July.  Original steel rudder is also still available, fully welded.  ($120).

  Horizontal Stabilizer Kit -- $100 -- Includes 4130 steel horizontal spar with tack welded hinge points; wooden ribs.  Assembles on flat table.  First ship of this new Elevator Kit is end of July.  Original steel horizontal stabilizer is also still available, fully welded.  ($200).

  Elevator Kit -- $100 -- Includes 4130 steel horizontal spar with tack welded hinge points; wooden ribs.  Assembles on flat table.  First ship of this new Elevator Kit is end of July.  Original steel elevator is also still available, fully welded.  ($200).

  Tail Feather Hardware Kit -- $70 -- includes bolts, nuts, cable, tangs, stops, thimbles, sleeves and more.

  Fuselage -- $4000 -- a completely welded 4130 steel fuselage.  This is really the ideal fuselage for anyone wanting to build an ultralight single seat aircraft.  Taildragger configuration.  Powdercoating is available as an option.  ($800).  We don't recommend powdercoating:  it can hide rust.  It's a better idea to blow oil into the fuselage, and paint the outside with a high quality enamel paint.  (Clean it with ScotchBrite first.)

  Machined Parts -- Y Strut Attach -- $85 each -- In perhaps one of the best bargains in CNC machining, we are offering our new Y Strut Attach part for $85.  This is a solid aluminum part which allows attachment of the two lift struts to the fuselage in one single part, and allows the wing to fold backwards. A long time ago, the Kitfox Lite used a welded steel fitting here; we'd been using a different inferior scheme entirely.  This is the best of all!  This would be a worthy upgrade to any older Kitfox Lite -- you might need to change out the lift struts at the same time.

  Machined Parts -- Control Stick Column Control Assembly -- $250 -- this is available as a welded part (steel) or CNC machined.  It is a very complex part -- the most complex fabricated part in the entire airplane.  I have hopes of reducing the price of this part, but don't see how yet.  So it is $250.

  Machined Parts -- Rudder Pedal -- $40 each -- We designed and are now making rudder pedals out of CNC cut billet aluminum.  Of course, you need two.  They look awesome -- the old steel welded ones just don't look nearly as sharp.  These could be used on many different ultralight aircraft and experimental aircraft too.  Here's some important fine print:  in order to cut costs, we leave them tabbed to the bulk billet.  You cut them out, deburr them, and drill out the pivot hole.  If we did that, we'd have to double the cost.

  Machined Parts -- Brake Pedal -- $30 each -- The story is the same as the rudder pedal.  These are heel brake pedals.  You have to do a little work to make them pretty.

  Machined Parts -- Flaperon Idler Bellcrank -- $40.  Beautiful aluminum part replaces older steel welded assembly.   Comes as two pieces:  5 minutes of TIG welding required to finish.  You will have to finish drill and debur it too.

  Machined Parts -- Elevator Reverser Link -- $35.  Another beautiful aluminum part, replacing an older welded steel part.  You will have to finish drill and debur it. 

  Machined Parts -- Control Stick Pivot -- $40.  This is the part that goes inside the control assembly.  You will have to finish drill and debur it. 

  There are many other machined parts in our wing kits, but the above ones are available separately.  Continuing on...

  Flight Control Kit -- $300.  This includes 37 different line items of miscellaneous nuts, bolts, pins, cables, tubing, etc.  Basically, all hardware required to make the flight controls operational.

  Panel, Seat and Floor Kit -- $30.  This includes 4 pieces of plywood, for the seat bottom, back, and floorboard.  Also includes a classic plywood panel with precut holes for 2 1/4 inch instruments.  All pieces are precision cut on our CNC router.

  Fuel System Kit -- $50.  OUR KIT NO LONGER INCLUDES A FUEL TANK.  This includes a fuel filter, fuel line, an fuel on/off switch.  We recommend a 5 gallon $10 Walmart plastic tank, OR you can buy a nice spun aluminum tank from many different online vendors for about $150. 

  Wing Kit -- $1000.  This is a comprehensive wing kit.  It includes:  (4) Aluminum spars, (4) CNC machined lift strut attachment points, (4) CNC machined jury strut attachment points, (2) push-pull cables, 30 feet of preformed trailing edge aluminum, (14) wooden ribs (CNC Cut!), (36) false ribs (CNC Cut!), aluminum False Rib spar, and about 20 more line items of nuts, bolts, and stuff.  This covers two wings.  For those wanting more aluminum in their wing, Extra Cost Options include:  Aluminum rib upgrade for 10 ribs -- $200.  Also, for those wanting a carbon fiber spar, that option costs $2200 (swap).

  Flaperon Kit -- $400 for two flaperons, includes CNC machined mounting arms and all hardware.  NOW with easy wooden rib assembly.  I'll cover this completely in a post sometime soon.  Older Aluminum Bonded Flaperons still available -- $1000 for two with all hardware included.

  Lift Strut Kit -- $200 for all materials for both wings.  Includes 4 lift struts, rod end bearings, nuts, bolts, jury strut material.  Main struts are 1" diameter aluminum tubing.

  Landing Gear Kit -- $700.  Includes Left "A" frame, tack welded.  Includes Right "A" frame, tack welded.  Includes Straddle link, tack welded.  Includes left and right solid gear rods, tack welded.  Will require about 4 hours of competent TIG welding to finish, maybe less.  Also includes preformed steel rear landing gear spring.  Also includes 5x5 wheels, tubes, tires, and another 10 or so line items of nuts and bolts.  Options:  BRAKES are not included.  (You can buy Azusa brakes for less than $30 per side from Aircraft Spruce and they work well.)  MAIN GEAR springs are not included.  ($200 for a set of two, fully welded from us.  We also provide plans for you to make them at no charge with our kit.)

  Windshield Kit -- $130.  Includes a rough cut Lexan windshield, two more ribs for attaching to the cockpit top, and hardware.

  Fabric -- $110 for 20 yards.  You'll need to add tape, glue, primer, paint.... 

  Documentation Kit -- $70.  This includes a manual, wing blueprints (extended span), fuselage blueprints, flaperon alignment blueprint, rudder alignment blueprint, booklet (how to fly a Belite).  You can also order an optional CD of all of our engineering documents in .dwg format.  (The machined parts are also available in IGS format.)  We use SolidWorks.  With optional CD, the entire documentation kit is $200.

  So here's the fine print:  *** If it is not included in the above list, it is not included in the kit. ***  We know you'll need the following additional items, at a mininum:

Engine, Engine Mount, Lord Mounts, Propeller, Engine Throttle Control, linkage, nuts, bolts and hardware.  We are a Hirth dealer and recommend the F23 and F33 engines.   The engine mount for either engine is $300.  If you want a mount, you should order it with your kit.

Fuel Tank -- For the budget minded, we recommend a $10 tank from Walmart.

Cowling -- We sell our cowling for $350 + shipping.  Because they are very large to ship, if you want one, you should order it with your kit.  However, we regularly fly our planes without a cowling.

Firewall -- We no longer build or recommend carbon fiber firewalls.  We do recommend an aluminum 0.040" firewall, and we include a blueprint of it's dimensions in our documentation.  It is not included.  If you don't have a sheet of aluminum, it will set you back about $30.

Battery Box -- Aircraft Spruce sells a nice one for about $30.  Also, we don't include any electrical systems stuff.  No battery, no wiring, no fuses, no switches.  We don't provide that stuff.

Instrumentation -- We recommend you pick out what you want from our extensive line of Belite instruments.  Your aircraft kit comes with a wood panel ready to accept our standard 2 1/4" round instruments.  We don't include wiring, switches, or anything.  The minimum you need is an Airspeed Indicator and an EGT/CHT and an inclinometer (bubble).  We don't sell hour meters; Aircraft Spruce sells many different kinds and we've used some that work well (and many that don't.)

Glue, Paint, Primer... -- None of this is included.  Also, we don't include dacron tape, just the raw fabric.  We recommend Stewart Systems products.

AND FINALLY, if you made it all the way down here, and want to save a lot more money:  Order the kit with the fuselage 'tack welded'.  We'll knock another $1200 off the price of the kit.

Here's a scenario for how to get a complete airplane for less than $10K:

A)  Order the tack welded option:  $8000 - $1200 = $6800.
B)  Bring a trailer and pick it up in Wichita:  no shipping or crating, but you have to pay sales tax (about $500).
C)  Odds & Ends, including instrumentation, fuel tank, glue & paint:  $1000. 
D)  Nice used engine, with propeller:  $1500.  You fabricate the motor mount to fit it.

Total:  $9800, and you get a very nice airplane, brand new.  Do it with your child and help him/her learn!

I'm curious to hear your response,

James

P.S.  Caveat:  PRICING and SPECIFICATIONS are subject to change without notice.  While we've tried to provide a complete and comprehensive kit, we're always aware that we've probably forgotten something -- if it's not in the following list, it is not included.

The Electric Belite that wasn't at Sun N Fun

We didn't announce an electric airplane at Sun N Fun ... but I did fly an electric Belite late last year.  I was very surprised that I posted so many hints about our work in this area... got no response.

This particular project wasn't far enough along to bring to Sun N Fun, but it sure did fly nice.

Ultralight Aircraft with Electric Motor

Electric Ultralight Aircraft takes off

This electric ultralight aircraft was capable of excellent performance with short battery life.  It took too long to recharge.  I still give it thought, but haven't worked on it this year.  Should I?
