With GRAUPNER HoTT 2.4 GHz technology, the 9-channel receiver has a new hopping telemetry transmission high-frequency section with state-of-the-art components and state-of-the-art software. A hardware antenna diversity for optimal reception. Without additional sensors, the receiver voltage, temperature and signal strength parameters are transmitted.

With this receiver it is possible for the first time to control a multi-copter without using an external flight control. By eliminating the need for additional electronics and cables, weight can be saved and the remaining components can be tidied up.

The integrated flight control is fully configurable via HoTT telemetry, which makes adjustment much easier. The system implements the control commands very accurately and precisely, which quickly gives you a familiar feeling of flying 'especially in FPV racing.

Channel 5 can be used to switch between 2 flight modes. This can be used to switch to the self-neutralising position mode, which limits the inclination to about 50 degrees, or to the rotation rate mode (also called acro mode). In this case, there is no more angle limit and can be freely controlled via any axis, just like with a model helicopter.

The simple controller teach-in function makes learning the controller paths child's play. Once activated, all ESCs can be controlled and taught-in directly with the gas stick.

Maximum performance and stability is achieved by setting the roll sensitivity factor to the pitch sensitivity with unbalanced multi-headers. The gyro effect can also be adjusted depending on the gas, in order to still achieve high sensitivity with strong drives.

The following multi-copter types are supported:
Quadro X, Quadro +, Hexa V, Hexa I, Tri L, Tri R
This gyro receiver is used exclusively to control multicopters. The GR-18 (33579) is intended for use as a flybarless system or surface gyro.

More characteristics:

• Very direct control feeling due to the elimination of the additional transmission path to flight control
• Space-saving, as the flight control and the necessary cables are omitted
• Quick and easy gyro assignment
• SUMD output for external devices
• Telemetry support for own HoTT sensors and HoTT sensors from other suppliers
• Can be programmed and operated with all HoTT transmitters available so that a laptop is no longer required
