RE: 40%
Yes Jeff, you do need one. Start planning now, mid June arrival.
If you have all the stuff they are actually easier to get in the air than a 35%, no hinging to be done and working with all this room is really easy. Canister box is built-in, lots of room for fuel and smoke tanks, 3 rudder servo locations already built in, beautiful smoked canopy already trimmed, polished landing gear, CF wing tube.
Very easy.
