Tapio,

The F1D rules say:

"Model aircraft which can only be flown in an enclosed space and which
are powered by
extensible motors and in which lift is generated by aerodynamic forces
acting on surfaces
remaining fixed in flight, except for changes of camber or incidence. "

So a rubber band must power the propeller. We all assume that the
extensible motor can only be wound before flight, in essence the device
I am proposing would rewind the rubber motor while in flight. So the
model is still powered by an extensible motor.
