KK2 Mini - Motors are not spinning

Hi there,

i use a kk mini and Afro 20 Amp ESCs for my tricopter. I calibrated the esc manuallly over the reveiver but the motors are not spinning when i connect them to the kk2 board. The receiver test shows that every sinal comes in wright.

If i now pull the throttle up, the motors are not moving. The escs also piep in a regular period.

I have no idea what i have done wrong or why it is not working.

I have done every settings in the kk (like fine-trim, max points, motor layout..)



Standard value for throttle on the receiver test on the kk shows 1 and on full throttle 100 - like it should be.



Can anyone help me to get my tricopter working?



thank youmumbi2016-05-15 07:16:41

    Your ESCs think they are being powered up with throttle active. Check their calibration together with ensuring your throttle off position is actually off and trims set to zero. Some Afros don't need calibrating but yours sound as though they do.



    If using Futaba you must reverse your throttle for use with ESCs.

    so throttle trim to zero and what else?

    No. Throttle trim set to default. So long as you are seeing the correct figures of 0 and 'idle' shows when throttle stick is down, and 90 or more when throttle stick is up, on the KK Receiver Test screen, that is fine.



    If your ESC's are beeping constantly when the copter is powered up, it indicates they are not getting a signal.



    Can you post a pic or two of your wiring? Upload them to photobucket or suchlike and post the links here.WTWUK2016-05-15 08:18:15

    yeah. the problem was that i had too extreme throttle trim on the rx and the minimum throttle on the kk was to high. Now the motors are working. Thank you
