SRXL2 Serial Receiver & 6-Axis MEMS Gyro, 32-Bit ARM M4 Cortex CPU, AS3X & SAFE Failsafe Technologies, 20 Different Channels of Control, Forward Programming, Telemetry via Optional Smart ESC/Battery. Fly easier and safer by adding the FC6250HX Helicopter Flybarless Control System ...SRXL2 Serial Receiver & 6-Axis MEMS Gyro, 32-Bit ARM M4 Cortex CPU, AS3X & SAFE Failsafe Technologies, 20 Different Channels of Control, Forward Programming, Telemetry via Optional Smart ESC/Battery. Fly easier and safer by adding the FC6250HX Helicopter Flybarless Control System from Spektrum to your RC helicopter.
It's ideal for 3D aerobatic F3C Precision and Scale helicopters up to 700 sized aircraft. You get an SRXL2 serial receiver a 6-axis MEMS inertial gyro with a 32-bit ARM M4 Cortex CPU that processes proprietary advanced adaptive flight control algorithms. The result is predictable and precise flight improved tail holding and solid piro compensation as well as Spektrum's AS3X and SAFE technologies that deliver a failsafe mode to help prevent crashes.
