RC India

I am making a quadcopter using 30 amp esc and 2200kv bldc motors with apm 2.8 flight controllers. Sometime before all of my escs stated constantly beeping when connected to the flight controller and powered on but when I try to remove them from flight controller and do the calibration plugging the esc to 3rd channel and starting in throttle up and after 3..4 beeps lowering down the throttle and then the motor works perfectly even in this process there is not continuous beep but When I attach the same calibrated motor to apm 2.8 it again starts beeping even everything is fine in flightcontroller and it is perfectly calibrated too?? Please help me

Moreover, I have tried starting it in throttle down pos and even checking the supplies its completely fine the esc is simonk red

Which transmitter you have used

The transmitter used is fs-ct6b 6channel 2.4 ghz one again it is also bindes properly to receiver as when I directly plug in motors without apm everything works fine

Ok in my case i fixed this issue using transmitter
In transmitter setup go to End points and decrease the throttle value (channel 3) till the beep stop.

But I don't have a setup window in my transmitter and I am not able to do it using mission planner could you please tell it how to do

Then how you setup your flight controller

I have set it up using mission planner actually there is no screen on my transmitter and it is working fine when the escs are not connected with the flight controller. the throttle works correctly but when the lead is connected to apm then it starts beeping I will add the pic of my transmitter

Have you done the esc callibration if not please do it may be it solve your problem.There are lots of videos showing how to calibrate esc.

I have already done all the esc callibration. Thats what I am trying to tell that whenever I am trying to use direct esc motor and the tx rx it works completely fine and as soon as I plug it to apm the esc start beeping . Escs are calibrated correctly

Ok bro in my way u need to decrease the end points value.
And hope someone better helps you best regards 👍

Yep I have tried that I need help if anyone here notices

Try with throttle trim at minimum with throttle stick at idle.

I have tried this too but the beep is constant like every second whenever Connected to apm but direct connection of the same ecs and motor to tx rx and lipo battery works fine

Please sort this out sir as this is my final year project

Have you tried reversing the throttle, I don't have much of Apm experience, but generally this constant beeping means that the throttle is not set to its lowest position and as soon as you connect the battery the esc detects power and as a failsafe feature it starts beeping.

Share a video of whats happening, may be that clears the air. Thanks

Center all trims and try again, also make sure all switches are at 0 position
