200g: wing span 110-140cm (Ripstop or Orcon flim wing, Bird type ornithopter, normal flight, no acrobatic)
Motor like as AXI 2203, 2cell-3cell Lipo.

What's the differences between normal flight and acrobatic flight?

I think building frame from plywood and bamboo sticks will increase the weight.. At least use CF rod for the main spar...
