What are the penaltys if you was to get caught flying a light sport aircraft with a passenger with out any licensing at all , i live in alaska, After seeing the U-tube video, I now have to have one. Bias cut fabric is particularly fragile. That's why, in addition to the structural strength it adds, foam wings and fuselages are always sheeted and/or fiberglassed, before any finishing work can be done. There are motors out there. About: I got started making remote controlled airplanes from scratch as a kid. The wings are also covered with doped fabric. It is with aluminum frame, with the same foam core fiberglassed flying surfaces. The layup above was trimmed a bit, then some temporary formers were CA'd into it, so we could verify the retract operation. Once you've built the horizontal stabilizer, use the method above to create the "built-in" control surfaces. It looks like the fiberglass and aluminium are the worst in terms of fatigue problems. I will use Junker style ailerons and ungapped hinged simple flaps. Best of luck Peter and thank you for your enthusiasm and your contribution to experimental aviation! After sheeting the wing, simply draw the control surface, including the leading and trailing edges mentioned above, onto your balsa sheeting, on both sides of the wing. Consequently, the loads on the single structural members are low, too, so you can get away with foam-only ribs.

Plan Page Add to Favorites Quote Prints Me 163-1A ( 15 in. and noiseit can take wide soread pressure loads and even stress, yesbut VERY LOWso the area between the laminate and the foam simply misses a transition zone bcs no such material exists or is used, as it would be heavier amd thereby the whole idea is uselessbasically easy! Where could I find wing templates for a wing like the airfish 2? Very slick, and much easier to maintain precise fit and alignment. (Use the appropriate type of wire for your power requirements, and use caution.). We already knew how it would work, and wasted less time and material. The Mark III Xtra has become Kolbs most popular aircraft. I didnt realize that it can get so bad.

The airfoil above operates well in the range between 24 and 64 MPH according to the NASA Foilsim program and Aeval software. This gives you repeatability, which makes sense for a complex project.
