Hi All,

I pretty much learned how to fly thanks to the people on this forum a couple years ago with a 22E and a Belt CP, but now I'm back on here with a very unique problem with my electric Trex 600. I've been flying this one for about a year and couple months ago I upgraded the 6ch RX to a 7ch AR7000 unit. Ever since then I've been having issues with my GY401 gyro where it would not stay in HH mode and make the tail slider wonder over to one side where it would then stay. Specifics as follows:

Turn on heli in normal flight mode with gyro set to rate, all is good. Heli flies with gyro in rate.

Turn on heli in normal flight mode with gyro set to rate, then change to Mode 1 / Idle up. Heli will fly fine with gyro set to rate, but when you set it to HH the tail will slowly slide over to one side and stay there with gyro light flashing.

Turn on heli in Mode 1/Idle up and turn on HH....it will work fine with a solid red light on the gyro and tail holding rock solid. The same goes for if you turn on heli with HH already turned on etc.

So, right now it would appear that I can only get my heli into HH mode if I fire it up in Idle up, which can be dangerous if you miss something.


Please note that I've waded through many a forum and have tried different combos. I've been using the Gyro setup pages on my DX7 but have also tried running the gyro gain of the Gear and AUX 2 channels with similar results. If anyone could share how they overcame this or what they think might be wrong that would be greatly appreciated as I'm quite stumped and a little frustrated.

Also, note that the heli flies very well when it has been started in Idle up...I was just hoping not to have to plug the battery in when it's in this mode...I'd rather start in Normal flight mode with throttle on zero ;-)


Thanks for your time,

Tom
