Not sure what a Sprint 2 is. I've kinda drifted away from main-line on-road. Traxxas? Like to see image(s) of it when you get it ready.
I'll throw up (
) my parking lot racer just for grins. Put it together from stuff lying around the shop. Old Academy Griffin 2WD buggy. PowerPac is MaxAmps
2s x 5250 30C LiPo w/Novak 2s SmartStop
; Novak Atom ESC; Trinity 10x2 FW brush motor.
Runs out pretty good. Not a good drifter though with the buggy tires still up front.
Haven't shot it with a radar gun yet, but it's fast enough for me to have fun with.
Good luck. Know there's lots of fast PLR's out there. Maybe this thread will bring them out of the closet?
