FHSS, frequency hopping via up to 75 channels

Maximum immunity to interference through optimised frequency hopping and aerial diversification

Intelligent data transmission with correction function

Extremely high range

Range test and warning function

Low-voltage warning

Extremely broad receiver operating voltage range from 3.6 V to 8.4 V (functional to 2.5V)

Numerous failsafe functions

Key-lock function to plrevent unintentional changes to menus


Shorter response times can be set (10ms periods adjustable)

No additional delays due to module processors. The entire hopping management is done directly by the 32-bit main processor.

Synchronous servo travel due to simultaneous control of the servo outputs is possible in blocks of 4

Pilot feeling:

Extensively delay-free control reactions due to direct processing

Telemetry analysis in real time

Speech output of the timers, telemetry data, and warnings via headphone output

Repeat function and continue function for voice output can be programmed via freely assignable switches

Pre-selection of voice output to be used

Separately adjustable volume for beeps and voice output

Integrated telemetry display with 8 x 21 characters or 128 x 64 pixels, optionally in test or graphic form

Duration of display illumination: ALWAYS, 30s,.60s, 90s, 120s

Micro-SD card slot for storage of telemetry data, similar to a black box and to add model memories, MP3 player, and for firmware updates

PC software for analysis or display of the telemetry data via download

Buzzer signal programmable at the highest receiver output for L/S function, satellite receiver, simulators, flybarless stabilisation systems, et cetera

Model-memory-dependent binding, except for copied model memories

Wireless teacher/pupil function

Numerous flight phases programmable

Swashplate limiter

Motor off function

Numerous fixed-wing model and helicopter mixers

Other characteristics:

Simple, extremely fast binding

Free channel allocation (channel mapping), transmitter and receiver mixing functions, as well as all servo settings can be programmed simply

Binding of any number of receivers for channel expansion (maximum of 16 channels) The last receiver bound sends the telemetry data.

Future-proof thanks to the update capability via USB interface or MicroSD-card
