I built my prototype from the free DXF plans I offered on RCU a few months back. These plans show a new Compufoil fully symmetrical aerobatic wing without dihedral and medium/heavy thickness for mild speed. She built just fine for me and it looks great tell me what you think. A few other features are it’s a tail dragger, under wing servo hatch doors, and a forward fuel tank hatch that comes in very handy. Free plans link below.
