Medusa Afterburner V2 BL motors

Yep, best to direct solder in fact.

As for testing the kv, difficult without an rpm spinning guage thingy. If you set up the vehicle for a certain speed (say 40mph), then run the truck with the motor, it should be fairly evident if its the right kv or not- if its 1600kv on 4s lipo it wont be terribly nippy compared to a 2000kv on the same voltage and gearing.. (GPS or radar gun would help).
