Traveler brought this up to me a few weeks back. In his experience the Kyosho 4100kv motor was on par with the likes of the PN70 so knowing that it is off the pace of the 5600kv motor. With that said I would be willing to allow the 4100kv motor to run in stock with a caveat that if it starts to show a true performance advantage either here or in other race series we can roll back this decision.

That work with you guys?

Cheers,
Jim
