nahh, I think, flying should be fun.
The advantages of a helicopter is its instability, which makes it easy to turn, climb, decent.
in a Robbo you have to observe strong limitations and have a low inertia rotor system, so the funfactor is largely reduced, compared i.e. with a Cabri.
Even a JetBanger with two blades can be flown around with much more fun than a Robbie.
Before I would fly a Robbie, I īd rather get a fixed wing rating.......
