GP780:
●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.
●Suitable for all sizes of helicopters, from micro indoor to large 90 size glow helicopters.
●Metallic dampening plate built into bottom gyro casing, dramatically increasing anti-vibration and anti-interference abilities.
●Features 1520μs pulse wide and 760μs narrow pulse wide frame rate.
●Digital/Analog servo switchable.
●Reverse switch.
●Rudder servo travel limit adjustment (ATV).
●Mode switch for large/mini helicopter.
●Delay adjustment.
●Gyro locking mode and gain can be adjusted remotely from the transmitter.

This is the TREX 450 PRO Super Combo kit from Align. The 450 PRO is a completely new T-Rex 450 design by Jason Krause.

Building upon the extremely successful line of it's T-Rex 450 predecessors this new design incorporates the latest in technology to further improve it's great handling and flight characteristics. Single plate Carbon Fiber side frames not only create a stronger frame but also minimize the total parts count.

The improved servo and linkage layouts provide more accurate control to the swashplate and the completely new head design. The larger and more powerful tail uses counter weighted blade grips to achieve better response and holding power and at a reduced tail RPM which results in more reliability and less maintenance. And to top it all off a restyled canopy makes it a stand out from all the others!
