I was just wondering if anyone has ever performed a loop with thier corona, when i bought mine they guy said that it could be done, but that it would be hard to do.

There was thread about this on another message board (that RCU won't let us name). Apparently it is possible but you obvioulsy need to start with a LOT of height just in case as the fixed pitch Corona can't have the blades changed to negative pitch while inverted. You can try it in a simulator by simply flying a simulated CP heli but not adjusting the blade pitch as you do it, that'll give you an idea of what to expect.
