i am using this flight control board with my h quad but when i try the throttle nothing happens non of the motors spin its like the esc aren't connected im using turnigy plush 30 amp esc please help

Hi Martin, I've found that if you do the ESC throttle range calibration first then do the stick centering, it works better. I've had the same issues you mentioned. At times I would redo the setup process several times. One other thing you may want to check is to be sure all your servo wires are on correctly. Once set up, to arm you must pull the elevator stick down. These boards are capable of getting a multirotor to fly quite stable. Hope this helps and Happy flying

thanks for the help Ron but its still not working. i tried it several times but still nothing is happening now theres no solid blue light even. but do you think you can make a detailed video to shot how the i86 works and how to make it fly.
 RonRC 4071 points
Funny you should say that Martin. I'm currently in the middle of a re-model of our home to convert our garage into my shop and have a new garage in front of it. But back to the point, I have a quad I built just to test boards with. I plan to use it to do setup videos of this board, the HobbyKing Multirotor control board (KK board), the KK2 board, MultiWii and others. Sometimes I start over with these boards, from wiring to initial setup. If the manual is followed and the pots are put back out of the programming mode, This should work. If not, you may have a faulty board. I've set up several of these and I have yet to get one to work on the first try.. Arrrg! Hope you get it working.

Hi Giuseppe, could you possibly post some video of what is happening? this would help in diagnosing what's going on with your quad. All the best and Happy flying!

SUPRAKASH, You can't use it directly for that purpose. But you can use a v-tail mixer with this board to fly a wing or anything with elevons. The dip switches must all be in the down or off position. The last (#4) dip switch can be at the bottom for low rates or top for high rates. Hope this helps and Happy flying!

This is the board I initially had on my UFO. I had to turn the gains almost to max for it to fly with some degree of stability. Still, this is a great board but not for very large multirotors.
 RonRC 4071 points
Here is a little better video of this UFO when it had this board in it.

when i oprate my qwade motor 3 starte in delay i replace esc and motor and its the same
 RonRC 4071 points
In this video, I used an i86. This was before the KK2 was introduced. I later installed the KK2. However I had to increase the gains much higher than one would expect due to the inherent instability of this aircraft.
 RonRC 4071 points
Hi oferg, One thing I've been doing is to change the order by doing the ESC throttle range calibration first on the i86, then do the stick centering. Sometimes these boards can be a little frustrating. Hope this helps and Happy flying!

A warning to those using SimonK's firmware on their ESCs. When you disarm this board it gives a short full throttle pulse. Simons firmware is sensitive enough to detect this and as a result disarming is very unsafe. I found a thread on this issue and it seems that other ESCs work fine. Three stars because Simons firmware is popular and this should have been tested. I was using Hobbyking F-20A ESCs flashed with SimonK firmware version tgy_2012-06-10_d8f53c2. The i86 was setup as a Quad X 4 copter on normal mode. Credit me if this saves your face.

Was up in the air in less than 1 hour. super easy to get everything together. Make sure you get the male to male servo leads so you can connect your RX. Credit if you find helpful. Thanks!!

I think this control board has very dangerous bug. Just sometimes happend symptom that all rotor was rotate full rpm after disarmed action after landed. So, my 3rd quadcopter has been literally distroyed.. It's really danderously.. Anybody has same symptom?

I was used in the X4-copter.
The control board was not very stable.
Is regrettable.
I want to change the firmware.
