Now this is a hack, congrats. nit some 20 models and RNs are different on those..so his stuff had some worth, yeshis methods.crude! Peters plane will never get enough air time for fatigue to be an issue. it even evaporates under isulation fassades on houses on the hot sunny surfacesit stinks for years! Have there been any floats/wheel combo added to a ultra-lite? even PU foam cores delaminate simply bcs the guys or girls designing so desperately witj fiberglass( heavy) and carbon laminates( heavy as such, but not bcs of the carbonbut bcs epoxy soaks i to tje foam and epoxy is heavier than waterand needs a minimum thickness, so it,s useless under compression.the rest is taken by foamcores , low rated G loads or you need very thick wingrootsthat easy! ) It is known for its versatility, light weight, sporty handling and rapid climb rate. Some manufacturers/shapers had issues while others suffered less, I guess because of their choice of foam core as you mention. but with airplanes itls a daily treat? Its my understanding that the weight limits apply to the deflated balloon or blimp.

Using a Hot Wire Bow the wings are cut based on the template shape. You need to determine the local loads and then decide if foam alone will be sufficient. Though it may be adequate, Im not technically an engineer, This isnt the first time someone from the Flite Test family has done foam board manned flight. Building them from a kit evokes a sense of accomplishment and pride. The wing won't hold any fuel - the 30 pounds of fuel is located at the center of gravity. be carefulit melts when it becomes hotdon.t use styrole or styrene or however it is called regarding what chemical stage of priduction is wuoted. Useful load: 400-445 lbs. Next, I made a partial layup in a mold for a vertical fin, and tested it there. Weight is a prime concern but drag is not. wtf? There are several commercial devices made for cutting foam wing cores and other parts. One of these, which comes very highly recommended by several experienced builders, is Carnauba wax. The guys not rich, that only makes it worse stop leeching off your parents dude. that idiotic foam core ideasatbthe end i returned to combustion engines, wood, aluminium and epoxy/polyurethane.and i don,t use fabric! The top pair of images is the inside, and the bottom pair is the outside. The purple "dot' in the image is another item you may want to add, which is a hardwood dowel, epoxied into the leading edge of the control surface, which will serve as a mounting for a control horn. Very slick, and much easier to maintain precise fit and alignment. on Step 8, How can we make the wing with movable control surfaces using this process, Question Then, work the hinge until the aileron moves freely.
