Thanks Guys

Sadly I have already put 4mm connectors on motor wires so can't return it which is a real pain. WIll keep it as standby I guess.
ALready ordered Medusa motor so that will solve problem.

With regards to connectors, I thought about using deans but never really liked them after a couple of bad experiences when using them on helis. Didn't realise they were rated as high as 4mm connectors.

Nice idea doing you plugs at a right angle to reduce height, might try that. Did you cut open a little slot on the male plugs so the wire could slide in?
