Re:   Belite's Product Improvements ----- TOP SECRET MEMO #18

Mr. C.S.R.:

Thanks for calling me earlier today.  I appreciate your concern over the fact that Belite is preparing to offer a traditional opposed cylinder four stroke engine on a legal Part 103 ultralight aircraft -- this is indeed a gamechanger and will help re-awaken the ultalight marketplace.  Per your request for information, I returned to Belite's facility late this afternoon and took some more clandestine photos while most of Belite's staff was absent.

It was sweltering out there.  I can't imagine how they continue to work as daily high temperatures in Wichita are forecast to hit 107 degrees later this week... 

Also, as a side note, I was able to observe Mr. Wiebe briefly, and I noted that he now is sporting a slightly "Harry Potterish" scar on his left forehead.  What is with that man??  Between emergency room runs (a rumored six stitches on the last ER outing); welding burns; daily cuts; and odd bruises, I am amazed he still has his vision and his digits.  

I agree with your comments concerning their aircraft finishing methodology.  They are now able to create world class finishes on small aircraft, using less time and money than competitive approaches.  Per your request, I have enclosed some sneakily taken photos of the fuselage which is covered with burgundy metallic.

The engine in question has been verified to be a 1/2 VW with an all up weight of about 88 pounds, developing 45HP (as I mentioned yesterday), with dual independent ignition.  This puts it at less weight than other four stroke offerings!  It is truly an aircraft engine on an ultralight aircraft.  My understanding is the Belite is pursuing this engine approach due to the fact that 1/2VW engines have been flying for 20 or 30 years, with good results, and that these engines are available fully assembled at reasonable prices.  In order to support them, Belite appears to have developed a custom four point isolated engine mount.  I also understand that similar 1/2VW engines may be built from 'scratch', from common plans ($25 or $30), utilizing off the shelf VW engine components.  Even better for Belite and their customers, the engines are available as kits at very reasonable prices.

Here are the spy photos I promised you:

The above photo is a little better than yesterday's photo.  The exhaust pipes have been attached, and the magneto is reflected off the firewall in the rear of the engine.  The engine mount is clearly visible, as is Belite's custom developed heavy aluminum shock mount / engine mount plate.  BTW, I was able to see the alloy stamping on the firewall, and it was 7075 aluminum -- top quality aircraft grade.

Re:   Belite's Product Improvements ----- TOP SECRET MEMO #17

Mr. C.S.R.:

I was able to once again gain access to Belite's facility late this afternoon.  There were no employees in the facility, and I fear that I will be discovered.

As they are almost ready to load two planes into trucks to head to AirVenture (OshKosh), it is now quite clear what they are intending to show.

1)  First and foremost, they are introducing an "UltraCub", which is easily the best looking single seat cub look-alike ever seen.  The pictures posted earlier are the 'proof in the pudding', and the rumor is that their yellow aircraft was sold a couple of days after I leaked those photos.

2)  They are also preparing to formerly offer a vinyl covering option for their aircraft which is easy to apply over stretched dacron, and is offered in around 80 different colors, including metallics!!!.  The aircraft I saw being prepped will be shown at Osh with an absolutely gorgeous metallic burgundy / black / white offset marking paint scheme.  It is my understanding that they have discovered a 'blend' of three different covering systems that make this a winner -- Stewart Systems and two other products that produce a truly amazing look.

3)  I clearly saw a 1/2VW engine mounted on the front of the one of their aircraft.  It had dual ignition, including a magneto, and developed 45HP.  It uses far less fuel than 2 stroke engines, and is very reliable, as it has been sold for many years.  It's also proven -- 1/2VW engines have been used on Kitfox Lite aircraft in the past (the KFL was the architectural predecessor of the Belite.)  Even more fascinating, they've managed to reduce weight so that a full featured, ultralight legal, UltraCub can be built with the 4 stroke engine.  This was a stunner, and I have one photo of that engine which I will share below.

4)  It is clear that they have improved their wing design to use high quality low cost baltic birch ribs with aluminum spars.  This, combined with some other tricks, allows them to offer the 4 stroke option on a legal part 103 airplane, without the expense of carbon fiber.  Even so, carbon fiber pricing will be reduced and offers even more capabilities.

I'm just skimming the surface of what I've seen.  I'm hoping they announce price, show specials, and more details next week.

How to make an ultralight look like a Piper Cub

How to make an ultralight look like a Piper Cub!

Well, the answer to that question is to start with a Belite and put an UltraCub Turtledeck on it.  The kit costs $500.  It includes all of the precut formers, along longerons and lightweight dacron fabric.  All the formers are CNC cut Baltic Birch plywood or aircraft quality Douglas Fir (in either 1/4" x 3/4" size or 1/4" x 1/2").  All you have to do is cut the wood strips to the right length and use good glue and lots of clamps.

The building surface is the back of your Belite.  This guarantees that whatever slight warps you built into your fuselage will be reflected in the turtledeck, guaranteeing a good fit and a good look.

In the following photos, we're using our super secret upcoming four stroke demonstrator airplane as the basis  of this particular turtledeck and resultant ultracub.

The photos are very self explanatory, so I'll keep comments to a minimum between the photos.  We'll start with a photo of the completed turtledeck, so you can see what you are trying to make:

Completed Turtledeck for a Belite Ultralight airplane -- UltraCub
From left to right, there are six formers: A through F.  There are two window formers, and two window eave formers, four angle gussets, and four square gussets.

Start by fitting the "A" former, the window formers, and the "B" former together.  You'll need to cut off the bottom of the "A" former, unless you want to leave the turtledeck permanently attached to your plane.  Cutting it off allows the former to be placed over the flaperon cables.  Also check the fit of the tabs.  They are a very tight fit and will need some help with your file or X-Acto razor saw to achieve a perfect fit.

Bottom of A former is cut off as shown
Gluing the A and B formers along with the window former
Gluing the window eaves former
Window eaves after clamps removed; bottom longerons (1/4" x 3/4") placed and glued
Gluing C, D, E formers to bottom longerons
Gluing F former in place to bottom longerons
Gluing top longerons in place -- two 1/4" x 1/2" and one 1/4" x 3/4"
In the above photo, the longerons are glued using lots of clamps.  As they are bent, this will require making sure that the overall turtledeck structure stays flush to the fuselage.  You can see some big clamps along the side of the fuselage which help keep it all clamped down and square.

Use lots of clamps.
Side longerons (1/4" x 3/4") and front angle gussett glued in place.
Top corner longerons (1/4" x 3/4") glued in place.  Longeron is fitted first to butt into corner.
Top corner longerons and lots of clamps -- a recurring theme.
1/4" x 3/4" stiffener glued to back of B former.  
Angle gussett glued to top longerons on each side
Square gussett glued in place on C former.
Additional (sideways) top corner longerons glued in place, forming 90 degree angle longerons
Between Former stiffeners cut, fitted and glued in place.
The purpose of the stiffeners in the above photo is to prevent the bottom longerons from bending when the structure is covered with lightweight dacron fabric.  Of course, to work well, we need to add a second level of stiffeners:

more stiffeners on the higher level.
short longerons cut, fitted, glued and clamped in place.
90 degree square gussett on E former
All longerons trimmed off, view from front.

Your turtledeck is now ready to cover with Dacron fabric.
