While i am still a green horn with these heli's my Trex 450 was doing fine. I installed a CPII which has nothing to do with the gyro/tail and now all it will do is spin in uncontrolable circles all the right stick input and right trim will not stop it. I think i have probably screwed up a setting somewhere along the way but can't seem to find the issue. The gyro, a 401 is still plugged in to the rx (Berg 7L) as always. My tx is a 9303 airplane radio so the heli settings are limited. The tail was fine earlier. Any suggestions? I am willing to try most any thing at this point. Thank you.
