Reinforced foam formers?
I'm looking into using reinforcement glued to foam formers... they'd be maybe, 1/4 or 3/8" of 1/32" ply glued on each side of the former.
At the moment, my fuselage (5" diameter) is solid xps fomular 150, sanded and hollowed out. It works but is too heavy. I can do only so much to hollow it out because getting any tool inside....well there's just no room for a tool.
The other issue, I'd prefer to make the fuse by itself, then attached or mounted to the balsa airframe, not glued on. The balsa airframe is a very minimal backbone for mounting the servos, ESCs, etc
Anybody tried something like this?
Thanks

You might look into hot wire cutting. If you are building on a balsa backbone you can cut stackable sections that are very close to final shape. Most of your hollowing will be done prior to assembly.

For accuracy, I should mention the backbone is actually sandwiched 6mm depron with 1/32" ply on each side. It IS as small as I think I can make it. Pretty strong tho...
