This is a foam scratch built plane I named the Cess-nah!!! It is the best flying plane in my arsenal of 10. I tried to build it for $10 but because I added landing gear and actual hinges instead of tape, it ended up costing about $11. It took three days to build and I`ve been flying it for 6 months or so. I love this plane,. Motor- BpHobbies outrunner 2217-6, 25 amp ESC, 11.1v 2200mah lipo, three Bluebird 371 micro servos, 9" prop.
This technique of 3D printing the wing ribs to hold a true aerofoil shape worked out super well! Combined with foam sheets, packing tape and the lightweight wooden spar, it performs amazingly well!
