....I tryed changing the board and motors ....
I have not look at my KK2 board for a day or two, .....maybe 5-6 years. Make sure you have the layout of the motors (the rotation) correct. If the rotations are off, it will flip. Also you MUST power the KK2 separately from the power supply used for the servo. The servo causes too much noise for the KK2 to handle.

What software are you using on the KK board? That is an older board if I am not mistaken so you may need to flash it with updated software.

The layout are correct I check them 10 times a day lol !! But the servo is connected to the board it takes its power directly from the kk wich takes power from the first esc connection that’s how I had my first build and based on David windestal build, it flue perfectly

I know you have probably already checked this, but make sure the right direction props are on the proper direction motor. Just throwing ideas at it. It's been a long time since I built a multirotor. In fact I just pulled my old KK2.1 out of a box and flashed it with OpenAero to use on some fixed wings

Also, if I remember correctly, the two front motors spin in opposite directions. You may want to reverse both motor rotations and props to see if that does anything. You have nothing to lose at this point.

Its my recollection, the first ESC pin powers the board & the rest of the ESC pins are all connected together, that is the pos & neg pins. It would be easy to get servo power from a different ESC.

Yeah man keep throwing ideas on me maybe we will solve this at some point.. any how I tried all kind of things I Talked to 2 experts from hobbyking and still nothing changed.. happy to hear about your wing I tried one 6 years ago I never got it to fly I build it and but never tried it lol

Yea exactly the servo get its power from the board there no other way to give it powe other than putting and additional battery exclusively for the servo

Thanks! I have not built the wing yet, but it's on the production schedule, lol I was going to put that KK board on a plane I know flies well so I can have it pretty dialed in before I start messing with the wing.

I hope you get the Tri figured out soon. Hell, just add another boom and you got a quad;)

I looked at your picture and I have 2 questions. Is the tail boom motor different from the other 2? If so is that okay? I always had the same motors on the ones I built many years ago. Second question, have you tried to swap out that ESC extension from the tail boom?

I must disagree, on my KK board, ESC pins 1 are separate from the rest of the board. All of the other pos & neg pins are connected but are not connected to the pos & neg on ESC 1.

The motors are all the same sunysky 1250kv
The extension is for the servo not for the esc I can’t remove otherwise I could attach the servo to the kk board

Oh now I understand what you want to say I agree the -and + pins are not connected to the first pin otherwise the other esc could power the board. You suggest to connect the servo to second or third esc while leaving a the single signal wire on board ?

Yes. On my board, I use power from 2 ESC’s. ECS1 powers the board & ESC2 powers everything else.
