This is the Align GP780 Head Lock Gyro. Perfect for use with T-Rex 250 through 700 class helicopters. 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.

Align GP780 Head Lock Gyro
Completely agree, this gyro hardly work with 450 and cant do the job at larger helis; I had to buy Spartan Quark after log fight with GP780 over Trex 550, later on I had another GP780 trying to use with TT X50B, useless...)
