Quick Start Guide for the GY If you manjal not using a stock tail slider then use the other technique. Are you considering getting an Esky V2 micro heli? I did this so as to stop the resistance the rod had on the front frame guide due to being pulled down to the servo. A better choice for non computerized radios or if you are lacking a spare channel for remote gain would be the Futaba GY or the E-flite G90 for smaller helis. Is it worth adding to your fleet?
Make certain left and right inputs are checked, because many helicopters have asymmetrical tail rotor pitch change mechanisms. Check the servo direction. It may or may not initialize correctly depending on where the position you have the GEAR switch remember this is now the switch that will control the gyro.
The gain select lead is plugged into any unoccupied slot in the receiver that has a corresponding switched channel on the transmitter. One side controls heading hold gain; the other side controls rate gain.

Further adjustments are rarely needed as most pilot fly in ACVS mode all the time. If you the tail wags in a hover then decrease the gain.
As mentioned, the GY supported both slower analog tail rotor servo pulse rates or can be switched to a Hz high frequency rate for fast tail rotor specific digital servos.
A wheel with a hole drilled for the ball joint is preferred over a “star” arm because of greater rigidity. With the rudder link disconnected from the servo. My RC Helicopter eBooks are here to help you with those exact problems.
Team Futaba Tip #2
Confirm that no sub-trim or ATV is present in the transmitter in any flight condition on the rudder channel. Also keep your tail shaft oiled. Adjust the guides to acheive the least resistance. Make the connections just as shown in the manual picture to the left comes from the manual. For now set both to but later you may need to adjust this down a little to keep the gyro from ‘hunting’.

Hold the tail rotor stick full right and pull the control rod all the way forward. I also use a JR Ball link resizing tool to remove unecessary resistance from the ball links. Its simple set-up and solid performance characteristics have made it a hands down favorite among many sport helicopter pilots.
With the GY there is very little reason to use standard rate mode.
