i will give parallel a go to start, maybe a bit of toe in but move the steering ball joints to the forward position on the steering arms. wont that make steering quicker?(oversteer a bit)

Not quicker neccesarily I think - that's determined more by the specs of the servo...
It makes the steering less direct and the turning circle bigger. More stable in a straight line I guess.
Short turning and oversteer can be created by toe out and the longer setup on the steering arm. :y:

B)

I'd try avoiding running backwards (with higher speeds) in the beginning btw - until the brushes have had a chance to run in a bit. If they're still flat (like when the motor is new) that reduces the chance of small bits breaking off.
Very curious how fast is it! :woohoo:

ok so i dont know the polarity of the wires but if i plug it in and just tickle the throttle forwards slightly first to check its going the right way it shouldnt harm it. once i know it is right then i can use more throttle

There might be some indication on the motor itself to what's the positive side. ;)
Didn't it come pre-wired? That would be easiest of course.

you are correct mr Edou, it has a red and a blue wire,pre soldered, and next to the red wire is a little + sign :)
