.. o/p as in ?

I tried to change the motor, and the other one behaved the same way too

Try swapping out the ESC if you have an extra

I dont have extra ESCs but i tried changing them among them selves. The Esc at the M1 port always speeds up .. I think its someting to do with the board ?

may your rx stick not centering while at rest state.
to check that  move rudder and pitch sticks and watch the motors are responding correctly.

or auto leveling will be problamatic(accelerometer calebration issue)
to check that tilt M1 updards/downwards will the motor(M1) reducing/increasing speed.

i move the sticks on the tx and the motors move fine as they should but during the start the M1 speeds up

hold the quad above your head firmly, give a 30 to 50% throttle, the motors should start spinning.
1) all motors should provide lift, ie; the props blows air to the ground.
2) tilt the quad to each angles, pitch , roll first (to front ant back and then to side ways.)
   while doing this the motors on tilted side should speed up resisting the tilting action.
3) now move the quad in yaw angles, ie; rotate it to left side and right side, diagonal motors should speed up resisting this yaw action.

if any of above conditions not met , you have some setting problem in the KK board.

the M1 moves so fast i can hardly make any of the speeding up or slowing down ... What shall i do ?

anyone ? I also tried to run it alone ( all 3 disconnect except for the one ) and it still accelerates ... ive resetthe board too now, still the issue is there . help ?

pls try updating the firmware on kk2 board.

its already 1.9, the latest i guess

no matter how much I reset or calibrate the ESC now, the speed  issue is still there ... help anyone ?

Could someone tag or call VC sir here ?

sir, pls post your PID , settings.
some one can help you.
I can't give much help here, as I haven't yet used this board.

also, If i am right, I think there is an option to check the sensor o/ps on a KK LCD board. pls check whether the sensor o/p s are correct.
also try another ESC to the motor1 pin.

what is o/Ps

ive tried all the Permu and combi of this , anything connected to the M1 port of the board has issues .

o/ps means - outputs - lol.
well, if any ESC behaves alike in motor 1 o/p (sorry output) - there might be problem in PID settings or sensors.

P.S you don't need permutations or combinations to fly multirotor, really

LOL ok so what is the issue  ? it happens even on factory values

A video showing the issue :

Try flashing a different FW. Try Steveis 1.18S1 or 1.6++AIO.

give it a try, as I already said , flash some old f/w.
have you calibrated and tested your sensors yet ?

sensors are calibrated . I cant flash anything as i dont have the tools to do it ..

well, you can check the sensors, are working, I think there is such an option on board.

HOLY ... just reset PI values settings and the issue vanished XD

Thanks RIBZ

though it has the tilting issue now( tilts to the south direction ) . How do I solve that ?

you have to thoroughly go through the manual, and tune the PID settings, until your quad is balanced. PID values differ for each setup, so you are on your own there.

ok , and generally whats to be noted for PI settings ? like higher the better or what ?
