![]() Watch Ed's tape covering video for complete instructions. That gives 150 + 150 + 40 + 10 = 350mmĬut out the wing panels - two 350mm x 750mm rectanglesĬover one side with packing tape and use a plastic gift card edge to smooth it down. Thats roughly a 6" main wing section with 1.5" ailerons giving 7.5" total chord.įor this 190mm chord airfoil we need 150mm for the bottom surface, 150mm for the top surface, 40mm for the ailerons PLUS 10mm extra for the leading edge bend. Total chord = 190mm with a 150mm main airfoil and 40mm ailerons. 30% of 190mm = 57mm, so the spar will be positioned 57mm back from the leading edge.Ĥ0mm ailerons give sufficient stiffness and some aerobatic performance so now we have the overall airfoil dimensions. ![]() No extra former on top of the spar = 19mm thick airfoil, so a total chord of 190mm gives a 10% section.ģmm former on top of the spar = 23mm thick airfoil, so a total chord of 230mm gives a 10% section.Ħmm former on top of the spar = 26mm thick airfoil, so a total chord of 260mm gives a 10% section.įor this wing I decided on the narrowest option - 19mm thick x 190mm chord section.ģ0% back from the leading edge is what I'm aiming for and ailerons are included in the total chord measurement. Using the information from my Bending Better Depron Airoils tests: I wanted a speedy slope soarer so Max thickness will be a slim 10% of total chord. This wing will be 1500mm (59") wingspan made from two 750mm (29 1/2") halves, joined with a 7.6mm Skyshark P4X wrapped carbon fibre tube spar. I'll mainly cover the steps that differ from Ed's instructions so check out his superior videos for more in-depth coverage. It's basically an Experimental Airlines Armin wing with a few tweaks for the 6mm paperless foamboard and a nicely shaped airfoil. Following on from the Bending Better Depron Airoils article, this is the complete wing build.
