It's interesting to see the background work in creating a new motor mount.  We recently had opportunity to improve our MZ201 motor mount, and here's the result, in step by step photo fashion.  This is everything from raw placement to ready to fire up:

First of all, let's put the motor on blocks, adjust height, and ensure that the propeller is on centerline:

Lining up the MZ201 engine on a Belite Ultracub.

Then we put a laser on the rear of the fuselage.  It is lined up with the centerline, which is easily determined from the CNC cut rivet holes further forward in the fuselage design.

Using a laser to line the engine mount.

Using a level to find the middle of the thrust line.

The laser shoots through the entire structure from the tail forward and hits the thrust line.  See the red dot on the level, below?  Also note the square in the lower left side of the picture.  It is lined up with the centerline of the firewall, and the laser is lined up with it, as well.

Something for everyone...

One sneek picture of an amphibious float is somewhere below...

Pics of the Sky Blue plane with a turtledeck on it, builder tips for those builders seeking help, photos of a tricycle gear fuselage under construction, photos of a primed fuselage, carbon fiber spars, all for the ultralight Belite Aircraft.

By the way, my heart goes out to designers of amphibious floats.  Hardest design project, ever.

Carbon fiber spar with jury strut fitting.  Wrapped with carbon fiber rope and epoxied.

Another view of the sky blue ultralight Belite Aircraft.

Blurry picture of lift strut fitting, with carbon fiber rope and epoxy.

Messy job on the glue, but aluminum doubler (2.75" OD) over carbon fiber spar.  Tripler on inside root.

New design Belite door.  Coolest ultralight aircraft door, ever.

CNC cut frame on inside of door frame.  Note two pins for locking door closed.

We added corner pocket windows to this Belite.  Edge of  polycarbonate door panel is visible.

This side of the plane has a polycarbonate window installed.  Easily removable 'cuz we used Nutserts.

Swing the door up.  Someone really ought to add a gas lift strut.

Door hinge installed on top of door.

Calculating Center of Gravity in a Tricycle Gear Ultralight Aircraft

Please note: James' blog has moved to a Wordpress site. To access it, please visit http://jameswiebe.wordpress.com/. All posts have been transferred to the new site, and all new posts will only be accessible via Wordpress. Thank you for your interest!


A few days ago, I posted information on how to calculate the Center of Gravity in a Belite taildragger ultralight airplane.  Today, I provide an update for tricycle gear aircraft.

You should review my original post, here.  After you review it, consider the following example for a tricycle gear plane.

Note that the nose wheel has a NEGATIVE arm, as it's distance is negative from the firewall.  All other arms are positive.  Remember to weigh the aircraft with an empty fuel tank; add the fuel and the pilot weight as shown in the equations as below.

Center of Gravity, Tricycle gear ultralight aircraft calculations:

DESCRIPTION, WEIGHT (in lbs.), ARM (in inches), MOMENT (lbs x inches)
Front nose wheel, 70, -5, -350.
Main wheels, 180, 49, 8820.
Pilot, 200, 39, 7800.
Fuel, 30, 56.6, 1695.

Total weight is 480.
Total moment is 17965 (-350+8820+7800+1695)

ARM of the aircraft is 17965 / 480 = 37.42"

This aircraft is in the CG range. 

REMEMBER, you must measure the actual ARMs of your ultralight airplane using a plumb bob from the firewall, and the aircraft must be level.  (This may be a little easier to do in a tricycle gear plane, as the plane is mostly level to begin with.)

I hope you find this useful, no matter what kind of aircraft you fly.

Oshkosh Pics, once again

A few more pics from Oshkosh...  Earlier in the week, I was flying our Cub Yellow Trike.  What a blast!!  The plane is a FAR Part 103 Ultralight Aircraft.

Here is a short final onto the ultralight field:

Here's the view of the plane, with 'hover' mode engaged:

A couple of pics of the view from upstairs:

with a view looking towards the north part of the field.  Nice view!!

I'm exhausted.  Pilot briefings every morning are at 6:30am. 

Bunny Hops & Flying POV

I received a call from my daughter earlier today. She's currently a counselor at Camp Quaker Haven and it was the first time I'd heard her voice since she left last week.  She's also our 'corporate cinematographer', and has produced almost all of the videos that Belite has posted on Youtube.

"Hey Dad," she said. "Did you know that I posted another Belite video before I left Wichita?"

No, I didn't know that.

It's great having a cinematographer in the family!  More video to show people what we are doing.

I had taken quite a bit of video, shot from my Point Of View, while flying the Superlite several weeks ago. It does a great job of showing the world flying by while piloting an agile single seat airplane. You can see it here:

Also, we shot some video of our Trike a few weeks ago.  It's just a series of bunny hops, mostly up and down the runway, but it shows the gentle landing characteristics of the Trike. 

(A little off topic:  I flew both of these planes earlier today, in Kansas strong winds.  They handled the wind with no difficulty).

Anyway, here's the video of the Trike doing bunny hops.

The Trike has free castering nosewheel steering.  You turn the airplane by applying either left or right heel brake.  I'm reminded of when I first flew a Grumman Cheetah back in 1978 or 1979:  ground handling works basically the same.

How to configure a Ready To Fly Superlite 50HP ultralight!

I've created a spreadsheet that allows users to select different options to personalize their Belite 254. Do they want a taildragger, or a trike? Do they want a Superlite, or a really light version? What you may not realize is that these are all really the same airplane. The only thing that varies is the option selection.

The spreadsheet keeps track of option selections, cost, and weight. As a result, you can end up with any type of FAR part 103 ultralight that you want!

Here's our base spreadsheet. Have a look:

Belite Pilot Operating Handbook

Pilot’s Operating Handbook - Belite 254 / Taildragger / Trike

This is not an FAA approved document.

www.beliteaircraft.com


1. Safe operation.

The pilot is responsible for verifying that the Belite is in a safe condition for flight. This responsibility is only that of the pilot, not of any other individual or company.

2. Limitations.

2.1 The Belite’s maximum gross weight is 550 pounds. Do not exceed this weight under any circumstance.
2.2 Under no circumstances exceed 80mph CAS. Do not exceed 80mph under any circumstance.
2.3 Do not use flaps unless speed is 62mph or less.
2.4 Do not taxi in more than 12 knots of wind.
2.5 Demonstrated crosswind component is 6 knots.
2.6 Never takeoff or land with a tailwind.
2.7 Always ensure that sufficient runway is available for takeoff and landing.
2.8 Pilot weight must not exceed 270 pounds.
2.9 All aerobatic maneuvers, including spins, are prohibited.
2.10 Do not exceed 2 Gs of wing loading (positive) or 0 Gs of wing loading (negative). (The carbon fiber wing has been static tested to approximately 3.8Gs positive and -2Gs negative, but this has never been demonstrated in flight.)
2.11 In order to maintain FAR 103 legal flight, ensure that empty weight does not exceed 254 pounds (without parachute) or 278 pounds (with parachute). Also ensure that level flight does not exceed 62mph under full power. (Utilize a ground adjustable throttle stop as necessary, or change propeller pitch.) Compliance is the responsibility of the pilot.
2.12 In order to maintain FAR 103 legal flight, stall speed must be 28mph or less under specified conditions. The wing design used in the Belite design is very heavily undercambered and is an excellent choice for slow stalls and slow flight. It must be possible to demonstrate a stall at 28mph when Belite weight is 254 pounds or less, pilot weight is 170 pounds, and fuel weight is 30 pounds. Compliance is the responsibility of the pilot.
2.13 In order to maintain FAR 103 legal flight, usable gasoline capacity must not exceed 5 gallons (30 pounds). Compliance is the responsibility of the pilot.
2.14 In order to maintain FAR 103 legal flight, cruise speed must be limited to 62mph or less. This may be achieved by engine selection, propeller selection, or by throttle stop. Compliance is the responsibility of the pilot.

3. Demonstrated takeoff performance.

The Belite has demonstrated a ground roll of 330 feet in medium grass and no wind, with a density altitude of 2600 feet. This was achieved with approximately 37 horsepower. Additional horsepower will substantially shorten takeoff roll. Conversely, reduced horsepower will substantially lengthen takeoff roll. At sea level, we estimate that a takeoff roll of 200 feet will be required with 37 horsepower (dry pavement, no grass, no headwind, standard conditions). Takeoff rolls of less than 100 feet have been observed under conditions of increased power and/or headwinds.

Sharpness

Chapter One: Clouds

The recent rains and intermittent sunshine have caused the countryside around Wichita to explode with green. Planted fields are already substantially sprouted. Trees have all their leaves. Plowed fields provide a dark, wet contrast.

I am looking it all over; I am sitting in my airplane, looking out. To the north, I am struck by the dark charcoal clouds. They are hanging over the fields -- providing even more enunciation of color, dampness, wetness, nature. 500 feet off the ground; perhaps a little more. Occasionally my altitude wanders lower.

The clouds are like slashes of charcoal across a matte paper.

It has rained heavily. A creek is roaring between its banks -- all waters are thick brown. A bit of foam dances up to one bank, but somehow is repelled away. The vision recedes behind me.

I cross the Kansas turnpike. I see a plaza between the lanes. Cars can pull in; get gas; eat at the McDonalds, and go on their way. I wonder who is looking up from the cars, and what they think of my airplane. I'm sure almost all are puzzled: my airplane looks like a dragon.

A few days ago, a trio of deer had run across a field while I circled my dragon above them. Did they see me? I saw them.

I am, in some oblique sense of the word, wasting time.

I find myself once again flying over my friend Terry's home. I don't see his truck; I do see his airstrip. The airstrip is oddly hidden, because of the depth of the grass. (Terry, it needs to be mowed.)

Glancing at the gas gauge, I see 60% fuel remaining. Lots of time to continue to waste.

I can feel a bit of vibration coming up through the heels of my shoes. I've not noticed it before. Like many other pilots who've mused over an odd vibration or sound, I start to think about what could be wrong.

Nothing. Nothing is wrong.

Looking south, I can see 30 or 40 miles to the horizon.

Looking to the north again, the sky is a little hazier. The north horizon is not nearly as sharp as the south. There is more humidity in the air.

An odd thing happens: it starts to rain. Just lightly; but enough to patter the windshield. The doors are not installed on this airplane, and even so, I remain dry.

I have my leather coat on. I'm also wearing a stocking cap, noise cancelling headphones, and light gloves. It's a perfect combination. I can feel the wind beating on the sleeves of the coat as they rest on the sides of the fuselage. My torso and head stay in calm air.

Now I'm even more relaxed: I've pulled my feet off the rudder pedals. The airplane now moves wherever I want it to using just the control stick.

Above the clouds, the sun is shining. Below the clouds, there is ample evidence of the sun and its working: green-ness; creeks; fields; rain; cool flyable air; much more.


Chapter Two: Technicalities

The Belite uses a 5 gallon tank. The purposes of my flight today was to verify instrument functionality and to also nail down fuel consumption. We I flew the plane for exactly one hour and then measured the reserve. I had 1.6 gallons of fuel remaining.

This means that the Superlite fuel consumption with a Hirth 50HP F23 engine @ 5800RPM is about 3.4 gallons per hour. This allows 1 hour and 25 minutes from full to dry tank. Based on a cruising speed of about 60 mph, this gives a reachable radius of about 75 miles in calm winds. I may be able to improve this a little; I've ordered a cruise prop to go with my engine.


Chapter Three: Crosswinds

Our airstrip is 2600 feet long and about 75 feet wide. Beyond each side is an ample unmowed area.

A few days ago, we had a very blustery crosswind.

I looked at the runway a little differently. I walked across it, and picked up some grass. Tossing it up, and looking diagonally backwards, I saw a new runway, constructed by landing on the existing runway diagonally.

"I know what you are doing," said Doug, who runs his small business out of a hangar close to mine and had walked up behind me.

Doug practices whenever possible in one of his helicopters (he's a dealer). He understands the importance of practice, and he saw that I was trying to increase my practice time by overcoming the crosswind blues.

Comfortable with my new 'make-do' runway selection, I took off into the sharp crosswind. I started making circuits around the pattern and the field, re-creating the new pattern.

My new pattern works beautifully. I land without event, diagonally across the existing runway. I take off again. I land in some slightly taller grass. The feeling of moving through the grass on touchdown is ... I struggle for the right word. Great?! Wonderful!? Smooth?? These are not the right words.

There is no adequate word. Landing in the taller grass makes me feel like an adventurer. I don't know how to put that into one word.

This reminds me of when I landed in the flint hills, nearly a year ago. I remember the flow of the grass in the wind, and the feeling of gentleness, as my airplane settled into the thick grass on touchdown.

I take off and land again. Each landing builds confidence.


Chapter 4: El Dorado

The lineman at the El Dorado airport can't believe his eyes: He's never seen a plane as small as mine. We full my gas tank up with 100LL. Total bill, about $8.

Smallest plane he's ever seen; smallest gas sale ever as well.


Chapter 5: Instruments

I occasionally glance at the instruments on the panel. I like what I see! The clouds have completely blocked the sun; I flip the switch over to the 'dim' setting. The LEDs in the panel have a soft glow.

I roll the plane into a turn to the left; the turn gyro shows the turn. I note that my trim tab on the rudder is not quite set correctly: the slip indicator shows a constant 'one dot' slip to the left. I see that I have 30% of my gas remaining: perhaps it's time to land. I've throttled back and the airspeed is showing 55. All is well.

These instruments provide a sharpness about the condition of the airplane: I know my range; I know my speed; I know if I'm straight and level; I know how I'm doing. I like what I see.

I look back at the ground. There is so much green, and so much sharp definition between fields, prairies, creeks, horizon, and clouds.

I can't wait to fly again.

Pics of new avionics while in flight

This will be a short post. I went flying tonight for about an hour in the Belite Superlite Dragon. I wandered near Augusta to try and find Terry's strip -- sorry Terry! Didn't bring a GPS and couldn't find it. Turned around and headed back home.

I took some photos of my new panel while in flight. You can see that the inclinometer (ball) is centered, I've got gas in the tank, the volts are about right, my turns aren't too fast, and I'm about 800 feet off the grand.

I'm having a little trouble with the CHT/EGT gauge -- hopefully I'll have that squared away in the next couple of days.

Did anyone see the dragon fly overhead?

Featherweight Avionics

Gene and I have made several panels for a variety of our aircraft. They were a mixture of basic instruments: airspeed indicators, altimeter, engine gauges, inclinometers. Basic stuff.

I'd run into a few problems with instruments breaking; also a few problems with inaccuracies. I was tired of weight. I started to think about ways to improve that panel. My 30 years of experience in electronics kept nagging me: I just had to develop some good, inexpensive, state of the art instruments.

A lot of very good companies produce fantastic, expensive stuff. Almost all of the direction of the industry has been towards more integration and more expense.

Why not break that trend?

Why not design basic electronic instruments that replace old fashioned steam stuff, that cost less, that works better, that weigh about a dozen grams, not a dozen ounces or even one or two pounds, and that more quickly alerts (using bright LEDS) to marginal conditions such as low fuel or redline speed? How about instruments with no dials to twist?

Well, that's what I did.

We introduced 10 new instruments to the market. I won't pick at the details of each here (see our avionics page for details). I'll just mention the key points of one of them.



Let's talk about our Turn Rate Indicator:

1) It truly has a solid state gyro in it, and it's incredibly sensitive.

2) It's designed to show a standard rate turn. And several other turn rates.

3) It uses different colored LEDS to quickly show when a turn has begun.

4) The LEDs are bright, easily observed in a bright cockpit.

5) You can see them with sunglasses on, even polarized sunglasses (unlike many LCD screens.)

6) And unlike mechanical gyros, it's inexpensive (about $150).

7) And also unlike mechanical gyros, you can buy it in a tiny box (3 x 2 x 1 inch) which you can velcro to any panel. It runs off an enclosed 9v battery for about 14 hours.

8) Or you can buy it with a standard 2 1/4 inch cutout bezel.

9) Or you can buy it with an even smaller 1.75 inch square bezel.

This is how we approached the design of each of our instruments: Lots of installation and use options, bright LEDs, simple operation, really low costs. Great for experimental, homebuilt, patch flying, ultralights, and perhaps a few other markets as well. (Helicopters? Yes. Gliders? Absolutely.)

My daughter Jennifer prepared a great video demonstrating the Turn Rate Indicator. You can see the video here. If that doesn't work, go to belite's channel on youtube and you'll find several more of our avionic and flying videos.

Even though the concepts are simple, the electronic technology has been a tough at times to tackle. In order to protect the work that has been done, we recently filed 9 patent applications on our technology. As a result, our designs are 'patent pending', which is a great thing as well.

The entire instrument panel pictured at the beginning of this post weighs about 12 ounces. That includes the basic metal plate, and all of the instruments. This is one of the developments that continues to ensure that our aircraft are the best and that our avionics (and aircraft) customers have the easiest to use, lightest, least expensive and most comprehensive goodies in the cockpit.

I appreciate your feedback. I was given several great ideas for additions to this new product line at Sun N Fun -- we'll work on some of them and hopefully show even more avionics at Oshkosh. In the meantime, this is great new stuff.

Finally, these avionics are 'on sale' for this first week of their introduction. You can order them with discount code SUN10 on our webstore through the end of 2010 Sun N Fun, (april 18) and this will give you a 20% discount!

We are also intent on adding distributors, both here in the US and overseas. Interested? Let me know.

On the eve of four announcements

It is Sunday evening; my wife and I have comfortably settled into our rental home in Lakeland Florida. Sun N Fun starts in two days. Tomorrow, we're sending out four news releases.

We're exhausted. Our staff and us have been working nearly around the clock for the last couple of weeks, trying to get everything ready and buttoned up for the show.

Most of my time has been spent on the development of a suite of avionics -- you'll be able to read about them soon enough. I've already concluded that once you fly with our new air speed indicator, you'll never use any other air speed indicator again. Ours is designed from the ground up for slow experimentals and ultralights. But it's just one of ten or so new avionics we're introducing, and it is by no means the coolest. Enough said on the avionics, or I'll spill the beans prematurely.

I asked for feedback on the Trike several weeks ago. You responded; and we completely redesigned it. Take a look at the pictures which have been posted on flickr
and you'll see that the Trike is now identical to our conventional taildragger model. And you can switch back and forth easily!

The Trike pictured is powered by a MZ202 engine with 45 horsepower. It uses carbon fiber wings, and tips the scales at about 250 pounds. Amazing.!

That's all for now.

See you at Sun N Fun in two days!

James

Need input on the Trike

The Trike demonstrator has not flown since we returned from Sebring. It sustained some very minor damage as we were loading it into the truck for the return home; the Superlite was a higher priority for us to work on after we got back. Also, the move into our new workshop location had consumed four weeks of our energy.

Based on the number of inquiries on the Trike, I know people want it and it's important to get this new plane up and running.

So here's my comments, and I want your feedback:

1) We redesigned the fuselage on the Trike to use an aluminum tail boom. You can see the black powdercoated tailboom in the photo above. It looks cool. It was supposed to save weight and reduce production complexity. It doesn't really save any weight, and the additional welding complexity on the tail feathers and rear landing (now main) landing gear largely offset welding savings on the rear fuselage. Should we use the original steel welded fuselage? Or stick with the aluminum boom?

2) The main gear of the Trike were designed from the ground up to use fiberglass rods. Although strong, this involved creating a couple more weldments that require fabrication. It would be easier to use an 'A' frame rear main gear similar to, if not identical, to our existing gear on the taildragger models, and forget the fiberglass rods. In other words, changing the gear design will save some money, and make this plane more affordable.

3) The nose gear works great; but we've discovered that the strength of the aluminum on the gear is a little marginal. Nothing really to discuss here; we're rebuilding the nose gear with some stronger aluminum.

4) The ground clearance is a little high, making taxiing tips slightly more likely.

5) I think many people want this with a bigger engine (think MZ-201 with 45HP) and light wings (think carbon fiber) so that it's weight legal in part 103. This would be an option, but would cost $$.

I have to make decisions on all of these over the next two weeks.

What do you think?

Flying the Superlite...

The first hints of spring are emerging in Wichita. Finally, we are seeing temps in the 50's and 60's. Yesterday was such a day, which was perfect timing as the Superlite was ready to fly again.

Since Sebring, we moved into a new shop out in the countryside. We've seen deer, all kinds of birds, it's great to have wide open fields and a grass strip right next to our workshop door.

The lift strut was redesigned; the new approach is easier to fabricate. Our thought process has been to ready the airplane (and wings) for some heavy loading tests.

So I flew the plane, late yesterday afternoon and early this morning. The tests were meant to explore the top cruise speed of the Superlite and to verify stall behavior.

I flew several passes at an altitude of about 2000 feet. Winds appeared calm at altitude, with runs in both directions producing GPS verified speeds of about 57 knots -- 2 knots too high. We will either reduce engine power by another 50RPM or substitute a climb prop (at which point this little bird will no longer climb like a bottle rocket, it will climb like an space rocket).

I noted that the indicated air speed for 57 knots was around 73mph. I'll be substituting another air gauge in the near future to resolve this gross inaccuracy.

I then did several power off stalls with full flaps. Indicated air speed was around 33 mph -- remember, the gauge reads way high -- and the stalls were just a gentle bump.

When we get the Superlite tuned up, focus will return to the Trike. Both birds will be at Sun N Fun for show and flight!

The Move out into the country

We're close to finishing up a move to our new location.

Our old production location was in a conventional office space with a production area attached to it. It was located in northeast Wichita, close to KAAO (Jabara) airport. Whenever we finished an airplane, we'd fold the wings and roll it about 3/4 of a mile down 34th street, then cross busy Webb road!

Jabara is a great general aviation airport, but it is not ideal for ultralights. Even so, I never had a trouble mixing in with the pattern. I kept my pattern a little tighter, and FWIW, I didn't have much trouble keeping up with the activity. But the frequent heavy traffic (eg, business jets and so forth) aren't what I want around when I'm testing aircraft.

So we planned a move to a new location. Our new production shop is at the Wichita Gliderport, which is about 3 miles from KAAO, but not on the sectional. We now have a great production facility, on field. We share our new home with about 15 gliders and a small handful of piston aircraft. We have two grass runways, each 2600 feet long. We get to help 'mow the lawn', and when the weather's good, our back door has a beautiful view of the glider activity, as well as the deer, hawks, and critters that roam around open places.

The last two weeks have been spent with the move, and there's still a little more work to do.

Things have been cooking on the sales front. While all of the paperwork is not yet in order, we've booked 3 sales over the last two weeks for kits. We have many hundreds of folks tracking our updates (by registering on our website), and I expect we have a good shot at selling every kit we can make this year.

I'll be busy between now and Sun N Fun. We still have some more testing and work to do on the Trike, along with getting kits out the door.

Thanks for your interest. This is an adventure! I appreciate all of your input -- you have directly affected our development path.

Speaking of input, one interesting thing I've noted is that our customers are more interested in the steel tailfeathers than in the carbon fiber tail feathers. I think you're telling me that you want to see more testing on those feathers before you're comfortable buying them. That's good input.

Another upcoming test is an expanded G test on our wings. Our last test took the carbon fiber wings to 4Gs. Soon, we want to test both our carbon fiber and our 'classic' aluminum spar wing to 6Gs. I'll keep you posted.

Best Regards,

James

New Aircraft Models to be introduced this week

Wichita went through a real cold spell in November, December and January. It was a difficult time to develop and test new aircraft models, but that's exactly what we did this winter. We'll put out official news releases tomorrow morning, and they are chock full of information on our two new aircraft models.

One is a tricycle gear model, and we are calling it the 'Trike'. How original!

The other is a very high performance ultralight, and we are calling it the 'Superlite'. Both were developed in response to the multitudes of feedback we've received on our classic Belite 254 ultralight aircraft.

Both are loads of fun to fly!

I had the joy of doing first flights and test flights on them. The Superlite was easy -- it flies exactly like our Belite 254, only on steroids. The Trike was a little more eventful -- since it used a new tail design, I found our first rigging was off and the first test hop required constant firm forward stick pressure. That was easily corrected, and the Trike turned into a flying (and landing) dream.

I just uploaded a video to our youtube channel, with an in cockpit view of flying the new Trike. Later this week, we'll have a video of the Superlite, especially showing its 'best in the world' takeoff performance. Yes, that's a big statement, but this little airplane can compete with the many of the best certified aircraft for takeoff performance and beat them.

Our aviation publicist guru Dave watched the Superlite takeoff yesterday and tried to take pictures, but he kept framing his takeoff shot, then have the plane disappear out of frame as it shot upward. You'll enjoy reading the news release.

You can visit the youtube video post of the Trike here: and if that doesn't work, just go to youtube and search on Belite Aircraft.

Ever since the start of the year, the number of purchase inquiries on our aircraft have increased considerably. That's probably due to a number of things: we've kicked up our advertising a notch, and we've gotten good press in a variety of magazines, both here in the US and in Europe.

Here's a little bit of weight information on the new Superlite.

SUPERLITE Weight in Pounds, then Kilos:

Aircraft with CF Wings: 142.2 64.9
Windshield: 4.5 2.0
Brakes: 6.0 2.7
HIRTH 50HP 2 Cyl: 78.0 35.5
Engine Mount: 4.0 1.8
Wood 2 blade 60 x 36: 4.5 2.0
BIG Tires: 15.0 6.8
Standard 5.0 gallon: 4.3 2.0
BRS Parachute: 21.0 9.5

Weight Totals in pounds and Kilos: 279.5 127.0

The astute reader and follower of Part 103 regulations will notice two things:

1) The weight is 1.5 pounds more than the maximum for a Part 103 ultralight with a parachute (277.99 pounds). Yes, I know. We've got a few things left to do before this new airplane is ready to deliver: swap the elevator to carbon fiber, swap the tail spring to composite, perhaps remove the tubes from the tires. This will shave the necessary weight. We could also swap out the BIG tires to smaller ones and achieve the weight saving objective, but the big tires look awesome and must be kept.

2) The engine is a 50HP powerhouse, and as a result, the aircraft cruises at greater than 62mph. The legal solution per part 103 is to reduce the engine power via a ground adjustable power stop, and we will do this for our Part 103 customers. But anyone who builds and registers it as an experimental can ignore this and fly it full throttle. When configured this way, you have a 50HP engine with a 280 pound airframe. Do the math, it's an amazing power to weight ratio.

Tomorrow morning, I get in a truck and will be driving these two new aircraft designs down to Sebring, and they will be on display at the airshow there. Hopefully we'll fly one of them as well.

I will also be posting pictures of both aircraft to my Flickr account:

BTW, we've also changed our production from the red plastic fuel tanks to really good looking spun aluminum tanks. They are more durable than plastic, and weigh about the same. We like them a lot!
