Tail kicking out in flips - any advice

[Sesame]

have been practising flips on my T-Rex 450SE using gy401 on the tail and ive noticed ( took me a time to figure it) but its kicking the tail out to the right during the manouver.

I would asume this is the gyro forces caused by the changing pitch and throttle during the movment, ive got the idleup throttle set at 100 90 100
wondering if the change in throttle is whats causing it.

any tips anyone can give me. to get it smoother and straighter.

Have you tried upping the gain on the gyro channel. On my V2 I've got it at 58 in HH.

Also I'd try 100 100 100.
