FY-901 Multi-Rotor Flight Stabilization Controller with self-leveling

A search for this product revealed that it has not been discussed before on diydrones.  The FY-901 is an inertial stabilization controller for your multi-rotor aircraft developed by FeiyuTech.

It offers two flight modes which can be remotely selected from your transmitter, even while in flight:
- Auto-Stabilization Mode: In this mode the FY-901 will utilize the 3-axis accelerometer to self level your aircraft
- Standard Mode/3D Control Mode: In this mode the device will utilize the 3-axis gyroscope to sense roll velocity and flight attitude while you keep control for aggressive 3D manouevres.

The flight controller has support for 4 speed controllers. You can configure it for flying in "X"- or "+"-mode as well as for Y3 copters through the switch on top of the casing. The gain screw allow to set gyro gain.

For more information, you can download the manual here: http://shop.fyetech.com/dl/fy901.pdf

Price for the FY-901 controller is US$ 89.00 and it is available from Hobbyking: http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=...

Does anyone have any experience using this controller? How does it compare to let's say the KK board? Obviously the pricing on the KK board is more attractive but does this board offer something other then a fancy cover when compared to the KK board?

Close race between FeiyuTech & Wookong.

FeiyuTech is way behind - they really need to dó much more work on the code. They told mé they Will focus on multicopter controller again. It would be wrong compare feiyuTech with DJI at this stage.

It would be more fair to compair zeroUAV with dji.

Yeah, physical pots to tune PID on a vibrating machine?  Silly.

R_Lefebvre i see you are a full supporter :)

try to build machines with less vibrations.

in a glider for example i see no issues...

I owned and tested FY-20A (plane) and FY-30A (plane, tri, quad). I would say that even cheap KK controller from HobbyKing have more logic and possibilities then any Feiyu Tech devices. I'm not talking here about bad support and a lot of bugs in FY you can find this by yourself. So if I need to made a choice I will spend $30 for KK without doubt.

Me also tested both FY-20A and FY-30A. The yaw gyro of FY-20A is a simple one( not heading hold). Both have high thermal offset. The result is incorrect leveling. See http://www.facebook.com/DragonCopter.

What you see from seconds 19 to 22 of the video is the effect of the thermal offset of FY-30A.

Has anyone tested KK on a Bicopter? The manual of KK has no details.
