RE: Brushfire or A-6 Intruder?
Mark,
You should be able to bring in my kit at less that 8 pounds. I am using lighter materials and techniques to make the fuselage plus I am using the lightest/stongest foam wings I can make. Quite honestly, I can't see putting anything over a .91 in the plane. I am presently building one for myself with a Jett .91 FIRE which I expect to be a rocket ship. One other thing... even with a YS .60 this plane will haul.... so.. I know we are in the realm of if it fits, us it, but I'd get the kit and start figuring out your weights before going with a 1.2 sized engine.
