My problem is the following: I had an unfortunate crash and one of the cables of a motor (the red cable, which I suppose that is the power cable) broke. The rest of my quadcopter is fine, I tested everything and it works.
Due to living in Spain, ordering a replacement motor from 3DR (the motor is the blue one from 3DR) would cost me 70$ thanks to shipment costs. What I thought was, could I solder the cable with tin and see if it works fine?
I haven't done it and I am asking for your opinions. Is doing this viable, will the motor receive proper amperage so that it goes more or less equal with the other 3 motors.
I also want to ask if it's possible to replace the motor with another different 850kv motor from EMAX.
Thanks in advance to anyone giving it's own experience, advice or thought about this.
