Motor 2 slows down, and is hot!

[Daveb272]

I have finally gotten around to finishing up my baby tri. after fighting with new clean flight 2.8 million, i managed to install 1.3. I set up the bare basics to make sure it works, and noticed that motor 2 does not start spinning as the others do. not only that, but after getting up to quarter throttle, motor will start loosing rpm, and eventually stop spinning. is this a motor issue, or an esc issue. Just an FYI, i am a complete noob, and i am surprised i made it this far. But i am willing to learn.

What is your set-up? Is it the first time you are running the motors? It could be motor shaft or housing rubbing somewhere, or it could be ESC.

this is the stock set up, and the props have not been installed. I am going to go over the solder joints, to make sure there are no straglers, but this is the first spin up ever, on battery.

First thing you should check is to connect to CleanFlight Configurator with battery disconnected (and props REMOVED!!!!), enter the motors tab, check the safety slider and move main throttle to max throttle. Connect the battery and wait for the ESCs to sound their beeps, pull throttle to zero and wait for the new ESC beeps. Remove the battery and your ESCs should be properly calibrated.

Then (with trottle at zero), reconnect the battery and check every motor, one by one, from the motors tab in CleanFlight Configurator. If they all work as expected there, the “problem” may be that your flight controller reduces the power to the motors since it does not sense the expected change in attitude and thus tries to “solve the error” by itself. Remember, the flight controller’s job is to stabilize the copter by adjusting the motor speed according to all the values it reads from receiver, accelerometer, gyro, barometer etc. etc. 😉
