This is the Align GP780 Head Lock Gyro Combo, with DS520 Servo. The Align GP780 is compatible with the three types of 760μs narrow pulse width servos on the market including the Futaba S9251, S9256 and BLS251. It features a new intelligent control logic that detects the current flying conditions and makes dynamic in-flight gain adjustments to maintain consistent pirouetting rates during chaos or other demanding 3D maneuvers. The GP780 also utilizes feed forward control logic to boost rudder starting speed and increase response sensitivity. It's Silicon Micro Machined (SMM) sensor provides excellent stability to dramatically reduce in-flight tail drifts while the AHTCS (Active Helicopter Tail Control System) compensates for any drift caused by wind direction and force as well as unintended yaw induced by the helicopter itself during flight maneuvers. The GP780 gyro features high sensitivity and minimal reaction time, fully utilizing the potential of modern high speed digital rudder servos. Another amazing feature is the Mini/Micro heli mode, which makes it perfectly suited for smaller heli's in the T-REX250/450 size range.

I dont get it. There are alot of bad reviews on this gp780. I think they're from people that dont want to read instructions. (Yes the gy401 is plug and play.) But.. The gp780 is sharp as a tack! Make sure that you have the correct esc, and or bec. Choose a trusting servo. Follow the easy instructions and play. I used the digital "green" feature with "digital align" servos on my 450-500-600 helis and all of my helis with this gyro feel like im on the simulator. 5 stars!, this gyro can take 3d to the top.
