Sharp Tail Kicks On Raptor 30

[mark Taylor]

Hi There
I'm Wondering If Anyone Can Shed Any Light?
I Have Flew My Raptor 30 For 10 Flights No Problem ,then Last Sunday After About 3 Mins Into A Flight, The Tail Started To Kick Sharply A Couple Of Times Over A Minute , It Would Only Kick Around About 3 Inches But Really Fast Left And Right.
I Am Running The New Dsx9 And A Ar7000 , Csm 420 With 9202 All Round With The Align Reg And Fp Lipo With A Step Down On The 9254 On The Tail
Any Help Much App
Cheers
M Taylor
