I bought a F550 kit complete with the motors/escs/props because I want to use it to benchmark flight times against the custom hexacopters I am building ( http://xnaron.com ). I took the motor out of the package and I noticed the way the leads come out of the motor (see pics). They don't come out flush with the bottom. I looked at one of the DJI arms and noticed the way the screw holes line up and the leads won't go out one of the side holes. If I put the motor on the arm the leads are going to get squished into the arm when I tighten down the screws. It usually isn't a good idea to put any undue strain on these wires. I have to think though that it isn't a problem with the number of kits they are selling. Is it normal for these leads to come out at such an angle from the motors and get squished into the arm when you tighten it down?

It'll be alright, just make sure the bullets are OK. They're not always soldered properly, one of mine came right off when I pulled on it a bit. That particular motor caused a minor crash that chewed up a bunch of Graupners and dinged one arm.

Thanks I will double check those.
