Looks like Align released another new product for January 2010.  The align GP780 3D Gyro.  Looks like it is the same as the GP750 but with better pirouette consistency and a few other features.   Read more for full details.

FEATURES:

• Brand new intelligent control logic providing dynamic gain adjustment by detecting current flying conditions, allowing for consistent pirouetting rates during chaos or other demanding 3D maneuvers.
• Utilizes feed forward control logic to boost rudder starting speed, and increase response sensitivity.
• Utilizes Silicon Micro Machines (SMM) sensor with excellent stability to dramatically reduce in-flight tail drifts.
• Utilizes AHTCS (Active Helicopter Tail Control System) to compensate any drift caused by wind direction and force ,as well as unintended yaw induced by helicopter itself during flight maneuvers.
• Tailor made specifically for use with high speed digital rudder servos. This gyro festures high sensitivity and minimal reaction time, fully utilizing the potential of modern high speed digital rudder servos.
• Features 1520μs pulse wide and 760μs narrow pulse wide frame rate.
• Digital/Analog servo switchable.
• Reverse switch.
• Rudder servo travel limit adjustment (ATV).
• Delay adjustment.
• Gyro locking mode and gain can be adjusted remotely from the transmitter.
