Great board that flies very stable and is easy to set up.

Here is my 900mm scratch built tricopter controlled by this board.

How do you reverse the gyros on the i86 board?, I've searched the web a lot looking for the answers and tried a lot of things but nothing works.
 RonRC 4425 points
Hi Janine, The gyros on this board can't be reversed. This board has a set list of configurations all in the manual that show the prop rotation and configuration. If you are having an issue with the setup, please describe the issue and I"m sure someone here can help you fix the issue. I've found that this board does a fantastic job of stabilizing tricopters for me. Hope this helps and Happy flying!

I get a weird problem with this on my tricopter. Basically, I arm the flight contoller and one of the motors doesn't beep. It sort of stutters and if I hold it then it beeps. It takes off then that motor cuts out and the tri falls. I did some playing: the motor works fine with its ESC (hobbyking 20A redbrick) not going through the flight board. I changed the motor and went through the flight board, same problem. I then switched two of the ESCs and motors (effectively switching the front two arms of the tri) and same problem. Then suddenly the other two motors did the stuttering thing and now none of them power up at all through the flight board. What's more, I switched flight boards and the same problem!! I resoldered EVERY connector and still problems. Is it my battery? It seems weird. It hasn't been charge for a while as I don't have a charger at the moment but I havent used the battery and my multimeter says that the battery is at 7.5v which is basically full for a 2S right? So I have no idea what is going wrong. Any help VERY MUCH APPRECIATED :/

I'd ordered two of these. And I have an issue with my Bicopter (clip uploaded in the video section here). The servos act weirdly despite switching to a fresh controller. This controller isn't near to what I'd expected!
 Callum 65 points
Yeah, I think in my case it was low voltage cut off since I hadn't charged the batteries for a while.... I've seen a lot of people with positive results from this board but I think it is pretty prone to difficulties in the beginning and the manual isn't great

you need to equalize ESC before Expecting rotor To Arm Otherwise. , because when first setup you Must Get ESC Process Equalize ESC before all else.. other wise you will see this Problem with Not Setting ,, beeps until set..So Make the process as I say stopped Me . Until I did Read ESC Throttle Calibration Manual,, Get the switches to TEST position first . ..! did you do hat other wise Motor Mifght Be Bugged. as they say . had the better days. Evan from New I get this problem often enough,. Board flies easy On mid setting s shown, good luck.

Hi Guys, I'm building a Bicopter. I'm unsure of the servo inputs (there are 2 servos which tilt the motors for yaw & pitch maneuvers). Could anybody tell where these servo leads should go on the controller?

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
 RonRC 4425 points
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

going to try this hopefully it works:)

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 4425 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.

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.
