I had a 401 with the 9252, my delay was set at 0 and gain was set around 70%, but since ive started using the 401 and the 9250 which runs a little slower 9252-0.07sec /9250-0.11 i cant figure out whats the problem with my tail in HH it will wag back and forth and sometimes it will go a full 90deg and hold for a while and then back to wagging, and when i switch to non-hh mode the tail spins to the left.
CAN ANY ONE HELP ME WITH THE DELAY SETTING AND GAIN SETTING FOR THE 401 GYRO AND THE 9250 FUTABA SERVO

If you want some good advice get you a 9253 or a 9254, set DS Mode to ON and you will have a worry free tail.

I second that. They 9253 and 9254 are made for that gyro.
