RE: Fun AIR 3D 40
Malcolmm,
Sounds great, You think it hav verticle with an OS .46 try it with a Saito .72. On pavment from Idle I can lift off within the length of the plane straight up. I removed some balsa sheeting from the underside of the fuse aft of the servo tray, glued in two pop-cycle sticks for reinforcment, and zip-tied my battery in through the fuselage, then just covered the hole with white monocoat.
A 10oz sullivan flex-tank fits in the plane well(see my review)
BTW what was your final weight
Dan
