Thanks, I've adjusted my tail rotor trim on the 3 in 1 already to about the 1 o'clock position and this seems to hold the tail pretty well I still have to input a little right tail to maintain heading which I don't mind. but my copter does like to drift to the left quite abit on take off and in hover. and i've checked to make sure the swashplate was level before I start and I've checked my trim on the RX and have still been playing with that. Sometimes it flies no problem other times it drifts pretty liberally, I was wondering if the gyro trim would help elminate some of this left drift. If you go back to the helimax website and watch the trailer for this model you'll notice about half way through the large file that when it shows a close up of the 3 in 1 both of these settings are at the 3 o'clock position. I know they vary from each model but didn't know if I should be adjusting these settings more than just a few milimeters at a time. mayby say like 1/16th turns or 1/8th turns at a time. I dont want to get to drastic as this is my first heli and I really don't feel like collecting parts off the pavement. Thanks for your insite. and answers so far.
