Electrohub HELP PLEASE

[mgray]

Hello all,

A couple of weeks ago I purchased the Electrohub quadcopter kit. After watching the videos, it went together very smoothly. After setting up the Naze 32 board I have come across an issue that I hope someone can help me with. I am currently using the featherweight lemon rx receiver along with a new Spektrum DX6 transmitter. The issue that I had was when I start the motors the back left motor is slower spinning than the other three. When I take off it works just fine after 30 seconds or so the multirotor crashes back left side first. I have done numerous calibrations of the ESC's and nothing seems to work. It seems to work a lot longer when I put the copter into angle mode. I was wondering could it be a bad ESC or motor?

Thank you any input would be greatly appereicated.

Still new as well - but are your solder joints good?

It could be a bad ESC or motor but I would check the fast and free things first...

Is the motor in question the same type as the other three? (as in same kv) It wouldn't be unheard of the manufacturer shipping the wrong motor out...

Same with the props... are they all the same? Orientation correct? letters facing up?

What kind of ESC do you have? All the same with the same firmware? Did you run through any programming with it? (would be in the instructions) mainly if the motor timing is correct for your motors.



If you go through all that and it checks out you could try swapping the ESC with another arm and see if the problem moves. If it does you probably have a bad ESC...If not you could have a defective motor.

Also make sure the bottom of the motor where the shaft is located is not touching your boom. It could be causing the motor to heat up or the esc is going into a protection mode.
