SP f3 flight controller issue

[UpMostBeast]

I am having a problem with my seriously pro f3 flight controller where one of the motor channels has a delayed response to stick input. I can see it on cleanflight where when I raise the throttle, motor channel 3 stay at 1070 (or whatever my min throttle is) while the others raise normally until the motor ouputs are at 1300 or so and then motor channel 3 begins to respond and raise at the same rate as the other channels are. Note that it doesn't matter which esc I am using ( I have some racerstar 20a lite using oneshot125) and the motor channel 3 works perfectly fine when I override it from within the cleanflight configurator. I don't know if this is a hardware or a software issue. I can note that the flight controller is actually a clone from banggood. Any help or knowledge would be appreciated .

Have you calibrated the ESC's?

yup. I did it using the throttle override in cleanflight while powering up the quad. it didn't help

Check motor, esc, do calibration esc, accelerometers and check wiring. It is extremely strange that a only one channel fails on the FC..

I don't think it is the esc/motor as I tried swapping the motors to different channels and the same result always happened with channel 3. Whichever motor/esc was on channel 3 would have a delayed response but the others would be fine. How do you check the accelerometer?

On the first tab in cleanflight there is 2 reset buttons. One for accelerometer other for gyro. Put the quad on a flat surface & reset both of them. It only takes 2min to set modes & pids if you didn't save them. I got a feeling it's just a board reset is all that's needed.

But it does happen, on a naze32 & on a spf3. A single channel just stopped working. Tried everything but they dead.
