typical hobby king. i bought this when it first came out wanting to put it onto a trickster as advertised. but as always empty promises here on hobbyking as it can't support tricksters even while 3d mode is turned off. also the software doesn't even work on mac while in the files they have stated "mac version coming soon" well its been over 6 months now and still no update and no support for mac books and tricksters. its a shame as the board itself is fantastic and built very well.

Just got a second one. Tried itout with Orange SBUS Rx this time.
You need to press RC calibration button during setup for the FC to scan the ports and recognise the type of rx connected. Rotation speeds 360 pitch/roll, 300 yaw.
Gain 100 basic and 50 attitude is a good starting point for 250-450 quad.

Yes, this is my 2nd review and after realizing the error was 100pcnt MINE I'm admitting it and giving this amazing thing the review it deserves.
1 - It fits in the smallest of copters and looks awesome.
2 - It performs better than any fc I've used (CC3D, NAZE). It has rock solid stabilization, and very precise movement.
3 - Its ridiculously easy to program once you download the software from the files tab.
4 - It's dirt cheap and outperforms fc's that are 3 times the price.

Buy it.

Absolutely awesome! Everybody must have one. Very easy to setup and works great.
I was flipping my quad around in no time. Start with 100 basic and 50 attitude gain.
Works great with SymonK flashed esc's even without OneShot but I recommend PWM (active braking) on. Wow Hobby King!

Does the job but not much else. Decent auto level but not many customization features.

Hobbyking sent me a defective board which the gyro "zero point" constantly changes on even after calibration. I will be contacting Hobbyking about this problem soon. I'm not the only one with this problem.

Started out great on my sk450 and by 3rd flight quad went crazy in the air.I've re-calibrated reset and went over this thing repeatedly it will not hold calibration Gyros are defective I have a video you can watch to see using the Mad Cow software how the Gyros think it's still moving even though it's sitting still. hobbyking did replace it for me hope this one is better...

I received this FC in May 2016. Connected everything and my transmitter is communicating with the board. I just can't the board to arm the motors.On the motor tab page when i press motor test nothing is hapenning. The save button also does does the same thing. I received a replacement from HK but it is still doing the same thing. Anybody has a solution ?

A great FC for beginners or experts. The GUI setup software is easy and intuitive and allows the option for basic or advanced settings. Out of the box the default, simple settings flew stable. 3d can be turned off to get a feel for the PIDs before trying inverted flight. I will continue tuning as I prefer a more crisp feeling response, however I haven't tried the current settings with 3d flight. One area of improvement - I would really like to see this fc include a barometer for altitude hold while inverted (version 2 perhaps?).

This is a great board....... easy to set up in the GUI.... flies great on my 250. The only down side is that the instructions dont show how the OSD is to be set up but I guess that will come sometime... Going to purchase another couple just in case..... for set up vids and info you can check out my youtube channel ..... moochasas .... here to help others.
