FC6250HX Helicopter Flybarless Control System (SPMFC6250HX)

The 6250HX is a Flybarless Helicopter Flight Controller with the added security of AS3X and SAFE Technology. Setup via Forward Programming makes installation and use intuitive, all right from your Spektrum Transmitter.


The FC6250HX is a powerful flybarless helicopter stabilization system that features the latest AS3X and SAFE Stabilization technology to deliver an extremely user friendly and precise Helicopter flying experience. Ideal for 3D aerobatic, F3C Precision, and Scale helicopter models up to 700 size. Featuring a leading edge 6-axis M.E.M.S. inertial gyro, powerful and fast 32 bit ARM M4 Cortex processor and proprietary Advanced Adaptive Flight Control Algorithms, pilots will enjoy predictable and precise flight characteristics, excellent tail holding and rock-solid piro-compensation with the added security of assignable SAFE technology.

SAFE technology allows pilots to operate within user defined flight modes that automatically keep the model in a manageable attitude and constantly levels the model when the control sticks are returned to center. Additionally, pilots can use SAFE technology to utilize a Panic Recovery option, which will nearly instantly right the model into an upright and controllable attitude to within 4 degrees of level. All these features are completely setup and tuned straight from your compatible Spektrum transmitter via Forward Programming Menu.

Forward Programming allows pilots to easily setup, program, and tune the FC6250HX with no need for extra hardware, devices, or computers. Pilots can quickly make tuning changes on the flight line to the swashplate, tail rotor, SAFE stability, flight modes and more, right from their compatible Spektrum transmitter. And if the sensor needs calibrated after a crash or repair to your model, it can easily be done in the Forward Programming menu. And if there is ever any advancement or changes to the FC6250HX, updating is simple with the Spektrum USB Programmer and PC programmer application.

So, I guess these don't have a barometer or gps? I'd like an auto-panic mode that does not allow heli to go below X feet that can be enabled once you takeoff. Idea is I could practice various maneuvers without fear of crashing since it should kick in and level the heli automatically when it gets to the set height recovery value . Is this feature available anywhere?

I do like this and may have to get one. I just kinda wished they made the whole unit metal instead of the cheap plastic top that will just bake in the sun and not look so good after awhile or just crack.

That H1 looks cool but there to much to add to the heli. I'd like a small unit with just a barometer that can have a auto recovery mode when the heli is too low. That would be cool. If anyone knows of a legit system with this feature I wanna check it out.
