Today I completed three loops with my EXI-450 helicopter - one messy but no crash and two rather pretty. I landed after each event to allow my heart rate to slow down. I did not need any negative pitch but just started in fast forward flight with slight decent and pulled through the loop with elevator. I used my original heli with the "big balls". I ordered my Christmas present a HK-500 heli from HobbyKing.com. It should be easier to see at a distance. My yellow glasses really help even in bright sunlight.
Next is ROLL!
