hello all
I have a hirobo shuttle plus, i have become comfortable with hovering it nose in tail in, so i decided to try some forward flight, i then put it into a hard left(or right) turn and there comes a horrible flapping shuddering sound, like the rotors have become out of track, i couldn't explain it(and nor could any one at my club) the possible reasons that i have come with
[ul][*] there seems to be some free play on the swash plate, [*] not enough torque on the servos[*] dampers to Hard/soft ?
[/ul]

please help me guys, busting to get back to those hard turns
regards
James
