The HC3-SX is a high-quality, compact designed Flybarless system (Rigid) and replaces the mechanical flybar on the rotor heads of all current RC helicopters. Additionally this unit features the well-known and patented Horizontal mode (self-leveling), which brings the heli back to horizontal attitude anytime you let go off the sticks.Moreover, the system is equipped with several safety features, levelling the heli back even while in hard 3D-manoeuvres like Tic-Toc or PiroFlip with a speed never seen before. These brand new features enable a pilot to learn 3D flying in the most safe way ever, speaking of a kind of real-flight simulator on highest level.
The stabilisation sensitivity (gain) as well as engaging or disengaging this function can be controlled via an auxiliary channel from the transmitter while in flight.
Because they are lighter, helicopter models without auxiliary paddles are much more agile and manoeuvrable, and are approx. 15% more powerful. In combination with the HC3-SX, 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 manoeuvres (F3N flying style), aerobatics (F3C), or hovering stability. All manoeuvres are performed with directional stability, i.e. with no disruptive influences at all, and with maximum stopping performance. This is achieved with minimum need for adjustment thanks to the intelligent and optimised control algorithms.
By means of the latest-generation high-quality silicon MEMS gyros, the HC3-SX has full 3D capability, whilst 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- and multi-blade) as well as all other flybarless helicopters such as trainers, etc., and, due to the possibility of engaging the Horizontal mode at any time, perfectly suitable for beginners.
The HC3-SX can be used for helicopters with electric motors or nitro/combustion engines as well as turbine models (in case of a turbine inside a scale canopy, please see the safety instructions in the manual on p.10!).
The system can also 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 swash mixing is done by the HC3-SX, so even a simple transmitter can be used.
The CNC-milled aluminium casing and the high-quality design comfortably meet 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 3.5m scale helicopters.
