A sturdy steel and aluminum construction, removable doors/windows and folding wings and tail complete the priced-just-right package. Some manufacturers/shapers had issues while others suffered less, I guess because of their choice of foam core as you mention. Rather than experiment on an actual fuselage, we made a simple two-layer layup over the bottom of our fuselage plug, after covering it with plastic wrap, to keep epoxy from sticking to it. Then drill a couple of small (1/8th inch) holes from the front (leading edge) side of the tube, through the tube and into the stabilizer about an inch or more. Both Upper and lower wing are removed as well as rear horizontal stabilizer. Probably the hardest thing Peter had to do was to wade through all of the misinformation available by naysayers who are expert armchair engineers with degrees from the academy of negativity. Styrofoam (extruded or expanded bead polystyrene) can accept epoxy, and certain other types of mild "white glues", with epoxy being the best choice. Very slick, and much easier to maintain precise fit and alignment. Foam does not provide a good material for hinging, so when you cut control surfaces for a foam core, you must face the trailing edge of the foam core, and the leading edge of the control surface with balsa. @jamesqf; No, it isn't. Next, any interior cutouts and/or installations are done in the foam, before it is sheeted and/or fiberglassed. Maybe as cheap as 500 dollars. Btw: The Velocity aircraft was conceived on that simulator, As I understand it, X planes builder and flight characteristics are based on the plank method and are not as accurate as XFLR5 for design analysis. It has high anisotropy imparted by oriented cellulose fibers. Henry Podgorny liked LED Coaster - Wireless/Batteryless. try to build a mold and spray PU foam of needed desity/stress strength etc into itoff course you jeed some foul or wax to take it outsome build that wayor you foam a block and cut all outand so onit.s still primitive amd many companies just before covid pisted NEW videos about their crude building processes! Four axis CNC milling A six foot chord and a 30 foot span provides for lift at 24 mph (14 with flaps down) and low drag co-efficient at the maximum level flight speed of 64 MPH. This was made in the traditional way, plotting individual ribs, inserting spars, and finally sheeting the structure. Just remember that with a two-place aircraft, you will be flying under GA Rules (Part 61 & 91). Now this is a hack, congrats. Spars made of fiberglass are the key to giving the wing strength. Using a Hot Wire Bow the wings are cut based on the template shape. Are ribs not supposed to be made of rigid, strong, woody and light material i.e pine,balsa etc.?
