Tricopter problem

No, plane mode is fine.

You might have to reset your throttle end points. It could be giving less "fuel" to the rear motor than the front.


I kept my radio setting stock, and made most of my adjustments in the board.

One of the really nice features of the KK2 board is being able to dial stick center to zero, and get my end points all to 100%. All without a computer, right off the push button screen.

Another thing i noticed was that when i give it throttle it pitchs up idk why??

do you mean throttle up makes to pitch's up? like nose up and wobble backwards? that sounds like a CG issue.

Yep thats exacly what it does, the more throttle the more it wants to go backwards. What can i do?

Shift weight to the front.

Ill do that and calibrate my esc's

Moved the weight to the front, it helps but stills go backwards on throttle all tho is not as bad. Also i learned how to trim the stable mode, so should i trim it forward or fix the CG? If so how?

Anyone got experiance with arduino and config.h? Or explain this to me and what changes will make it go up or down.The other option is to adjust mix in Output.ino Find lines #ifdef TRI motor[0] = PIDMIX( 0, 4/3, 0)* //REAR motor[1] = PIDMIX(-1,-2/3, 0)* //RIGHT motor[2] = PIDMIX( 1,-2/3, 0)* //LEFT ....... #endif Decrease 4/3 in first line and increase -2/3 in next to lines. The sum of all 3 must remains = 0.
