The HC3-Xtreme is a professional RIGID electronic unit and replaces the mechanical auxiliary flybar on the rotor head. Because they are lighter, helicopter models without auxiliary flybar are much more agile and maneuverable, and are approx. 15% more powerful. In combination with the HC3-Xtreme, huge performance is delivered, without the need to adjust the fragile paddle mechanism.

The all-round precision is outstanding, whether it is the extremely dynamic maneuvers (3D/F3N flying style), aerobatics (F3C), or hovering. All maneuvers are performed with directional stability, with no disruptive influences at all, and with maximum stopping performance. This is achieved with minimum need for adjustment thanks to the intelligent and optimized control algorithms.

By means of the latest-generation high-quality silicon MEMS gyros, the HC3-Xtreme has full 3D capability, while boasting a top-quality, ultra-fast tail gyro. No external gyro is required. In addition, a symmetrical torque control unit is in place there. The resultant further increase in retention force in the tail was possible because the tail gyro is internally coupled with the pitch data of the rotor head control unit.

Of course, the system is also suitable for flybarless scale helicopters (twin-blade and multi-blade) as well as flybarless helicopters such as trainers.

The HC3-Xtreme expressly contains no horizontal or position stabilization and is therefore fully suitable for competitions. The head gyro eliminates all unwanted rigid head properties, resulting in optimum control and precision.

All current analogue, digital and brushless servos are supported, including narrow-pulse tail servos (Futaba servos S9256 and BLS251). All current swash plate variants are also supported, including four swash plate servos and virtual swash plate rotation (H1, H3-90°, H3-120°, H3-140°, H4-90°, H4-90°/+45°).

The system can be used as a pure tail gyro, without the need of any additional accessories. Especially if a new heli project is planned, first using a flybar, later on switching to a flybarless head, the purchase of an external tail gyro is not necessary. Simply set the Rigid gains in the PC software to "0", so the Rigid mode is disabled.

The CNC-milled aluminum casing and the high-quality design comfortably meets the current quality standards of major helicopter manufacturers. The highly compact construction and the flexible installation possibilities enable use in almost every helicopter, from micro-copters through to scale helicopters.

Features:

- Set-up work is reduced to a minimum
- Clear separation of the sensitivity settings for the head and tail gyros
- Can be used as pure tail gyro without the need of additional accessories
- Direct USB connection for fast programming; the easy-to-use set-up software comes as standard
- The connecting cables between the receiver and HC3-Xtreme are plugged in on both sides
- Gold-plated circuit-board and the latest-generation MEMS gyros for all 3 axles
- The HC3-Xtreme is ready for connection to receiver systems with an SP serial pulse output, for instance with the Futaba FASST receivers, reducing the receiver connection to a single cable
- Consequently, the motor/throttle-servo output is available on the HC3-Xtreme
- A software update for connecting the device to the Futaba S-BUS system and other satellite receivers is currently in preparation

The HC3-Xtreme is equipped with a flash memory and can be updated in service to the latest software. This means that the system is open and can be adapted to enhancements in the software and helicopter mechanics field at any time
