Use thick wiring and good connectors. Keep the wires as short as possible, but enough to flex a bit.

Based off my experience in my smaller cars, I would say a 1515 is too small of a motor to turn those big tires at 60k motor rpm, for record breaking speeds. I would stay with a motor in the same diameter, but choose a longer can version like a 1518, or 1521 to gain the torque to turn a bigger gear.
Makes a load of sense snellemin. Course, I would say that as I'd already suggested a Neu 1521.

Mind you, I'm moving toward sensored at the moment, so the next motor destined for my E-Revo will be a Novak Ballistic 8L - When they finally release it!

Now I've just gotta choose between an RX8, an LRP iX8 and Novak's new Kinetic 8. depends how patient I can be!


Cheerz!
