Hi...I am a newb at this heli addiction and I bought a TT Raptor 30 as my first heli, an Airtronics RD8000 with servos, and a Futaba 401 gyro with its servo. I used Raptor Technique to get it set up and I can hover it. My question is why does the nose yaw slowly to the left all the time...I have to hold a slight amount of left rudder to compensate the whole time I am hovering. I have maxed out the digital trim to the left with still no help. Any ideas? If you need more info than I have posted then please let me know. Like I said, I am a complete newb and it is probably something that is obvious that I have overlooked but I would appreciate any help...


Thanks..


Mike

Are you running the gyro in rate mode or AVCS (HH) mode?

If its in rate mode you need to mechanically trim the tail by adjusting the push rod length. All sub trims on the radio should be set to 0.

If its in AVCS mode then make sure there is no tail mixing programmed into the radio such as revolution mixing. Also when powering up turn on Tx first make sure the gyro mode switch on the Tx is set for the AVCS mode and then turn on the Rx. Touch nothing including the Tx sticks for at least 3 secs while the gyro calibrates.
