Weird one here. So I have another quad I’ve been building. All good except that prop 2 was going round the wrong way. Used BlHeli to reverse the direction. Tested the motors both in Betaflight and BLHeli and motor 2 goes faster and slower when moving the slider up and down.
First test flight (I say test - hovering on the living room floor) and all goes well briefly when suddenly motor two judders and bit and then stops. One of the wires has come off. Aha I think dry solder, so I re do it.
Every time I solder the wire back on, it comes off. I do this two times and the wire and solder just won’t stick.
Aha - glue gun (solves all wiring problems ) Tried that and the glue melted along with solder. WTF
Multi-meter time; nope no shorts between the wires.
Ok, time to cut the cable, clean the pad (again) on the FC and use different solder.
So far so good, increase the throttle and it doesn’t come off. Only issue now is that the motor doesn’t spin any faster and judders if you move the quad around. (Props off at this point and I’m hand holding it)
I’m wondering if the ESC for motor 2 doesn’t like being reversed. These motors (Mr Copper 2306) are reversible so I’m wondering if there is some other problem.
Tomorrow I’ll try swapping the wires round to see if that fixes the problem, then reverse the motor in BLHeli back to normal direction.
Any other thoughts or ideas on other areas to look gratefully received.
