Thanks for the replys, been busy at work and did't have time to reply.
re the wire size the wire gauge out of the esc (30amp) is much larger than the wire size that comes as part of the motor so I guess I will try a size inbetween.
I was thinking of getting a clamp type amp meter but had a question, the current out of the esc is chopped at high frequecy and I was wondering if the cheaper amp meters gave accurate reading at these frequencys. I guess just reading the input current to the esc should not be a problem and as informative.
As I understand it the esc looks for little voltage spikes on the leads into the motor inorder to decide when to switch each winding and I'm affraid the extra resistance in the longer leads may not allow the spikes to form properly.
Pity you missed the big screen Steve, I'v just installed a data projector into a research lab, the screen is 2000mm high and 2600mm wide (that a 328cm dia) so I took in my laptop and ran the Great planes simulator on it. The bottom of the screen is at floor level and you stand 2.5 meters from it.
