General Tail wag

[Alanwhite52]

Hi I have just built my first Heli a Trex 450l dominator with 3gx and Futaba T10j radio my problem is it fires up perfectly very stable until I am just ready to lift off and the tail wags really badly I have checked the tail section is free and easy someone told me my tail gain is to high the problem I have is I do not know how to adjust it I hope someone can help many thanks Alan

First question is, do you have a green status light? If so then yes the gain is too high. You will adjust this on either channel 5 or channel 7. I don't know how futaba works. But there may be a gyro menu in the Tx and if there is, post a picture of it.

And I moved this thread to the correct section.
