The BEASTX flybarless system is a gyro system for modern RC helicopters. The system is used to stabilize and control the helicopter on all three flight axis. It can be used with nearly any type and size of helicopter - 3D aerobatic helis, F3C competition helicopters as well as scale helicopters with 2 or more rotorblades.

  • MICROBEAST ULTRA / MICROBEAST² is the latest device in the line up, featuring a modern ARM Cortex M4 microcontroller with lots of processing power.

  • MICROBEAST PLUS HD is the heavy duty version for big helicopters from 600 size and greater. It features an additional high power battery connector with failsafe switch to meet the demands of high power servos.

  • NANOBEAST is the ultimate system for micro and mini size helicopters. Basically, it has all the features as its bigger brothers but is especially designed for applications where small size and weight are important. Thus, it comes with special JST servo plugs that are compatible with micro and nano servos.

Technical specification

  • wide input voltage range from 4 to 9 Volts
  • supports nearly all types of radio systems with conventional receiver wiring as well as lots of different serial signal receivers like SBUS, XBUS, EXBUS, iBus, UDI, SRXL, SRXL2, TBS CRSF (OpenTX, EdgeTX and ELRS radios), FRSky F.Port, Serial PPM, SUMD, Spektrum/JR/ALIGN remote satellites (some protocols are not available on all devices, please see device specific instructions)
  • preset swash plate mixing for mCCPM and 90, 120, 140 eCCPM + fully customizable swash mixing with up to 4 swash plate servos and virtual phasing for scale helicopters
  • swash plate servo update rate with up to 400Hz (not on all devices, please see device specific instructions)
  • integrated tail gyro with torque precompensation ("RevoMix") supports all types of rudder servos with 760, 960 and 1500/1520µs pulse width and up to 600Hz update rate (not on all devices, please see device specific instructions)
  • integrated motor governor for electric and nitro/gas driven helicopters (requires rpm sensor pickup or esc with rpm signal output; not available for NANOBEAST)
  • also supports helicopters with tail motor drive instead of conventional tail drive with servo control

Additional features

All systems comes with basic flybarless stabilization functionality and can be upgraded with additional features by paid update.

  • AttitudeControl for recue bailout or constant leveling
  • Bank Switching which allows to change between different parameter presets in flight to serve different flight conditions or flying styles
  • Telemetry hub transforms your BEASTX device into a hub for processing incoming and outgoing telemetry data. It supports common ESC protocols (Kontronik®, YGE®, Scorpion®, Hobbywing®, Spektrum® AVIAN) and radio systems (Jeti® EXBUS, Spektrum® SRXL2, Graupner® HOTT, FrSky® S.Port, TBS CRSF, Futaba® SBUS2 (MB ULTRA), FrSky® F.Port (MB ULTRA))
  • The ProEdition upgrade unlocks all features at once at a fair pricing!

Setup procedure

To setup your BEASTX system there is no need for any additional devices. All you need is your radio system and your helicopter. Thanks to the well proven EasySetup system you can do all the necessary adjustment directly at the device and in very short time.

In combination with a Spektrum® or JETI® telemetry radio system, you can follow the setup process through the display of your remote control.

For additional features you can use the StudioX app for PC/Mac/Smartphone/Tablet in combination with the USB2SYS or BLE2SYS interface (optional available). These apps allow to setup your device, save/restore paramaters, download firmware updates, load preset heli configurations and make advanced adjustments to fully customize your BEASTX device.
