RE: Robbe Whopper
The damage looks more like hard landings rather than roll-over take-offs. Did she fly at all? Was it a hot humid day?
One thing: I know the Whopper flys using the original blades, but it's work. If you get her back together I would consider making up a set of AeroBalsa rotor blades.
I never managed a flybar hole in the fuse.
