FC6250HX Helicopter Flybarless Control System
The Spektrum FC6250HX is a precise flybarless helicopter control system with advanced AS3X and SAFE stabilisation, Forward Programming from your Spektrum transmitter, and Smart ESC telemetry — ideal for mini to 700-class models seeking rock-solid handling and easy setup.
Features
- Forward Programming from compatible Spektrum transmitters for setup and tuning on the flight line (DX, iX, NX series supported)
- AS3X stability with SAFE modes and Panic Recovery that rights the model to near-level
- Smart ESC Ready: displays voltage, current, rotor head RPM and more on a compatible Spektrum transmitter
- Compact CNC-cased unit with 6-axis MEMS gyro, 32-bit ARM Cortex-M4 processor and adaptive flight control algorithms; suited to 3D, F3C and scale helis up to 700 size
- PC Programmer app support for backing up and sharing model setups (requires SPMA3065 USB programming cable)
- Supports two DSMX remote receivers; adjustable servo frequency 70–560 Hz (760 µs and 1520 µs centre); works with digital and analogue servos
- Integrated telemetry and SRXL2 serial output; full-range performance
What’s Included
- FC6250HX Helicopter Flybarless Control System (SPMFC6250HX)
- DSMX SRXL2 Serial Receiver with Telemetry (SPM4651T)
- 4-pin ZH to 3-pin servo lead
- 3-pin male-to-male adapter
- (2) Gyro mounting pads
- Product manuals (FC6250HX and SPM4651T)
Needed to Complete
- Spektrum DSMX/DSM2 compatible transmitter (DX, iX or NX series)
