Traxxas .15 in a Traxxas Slayer Pro?

tmaxx couldn't get out of its own way with the .15. but the slayer is a lot less weight and i think 2wd (?) so it should be a good fit.
I agree. Especially the tire weight. I'm actually trying with a rwd nitro slash with a jato 2 speed...
 
Slayer pro is 4wd and.i have a locker in the rear
should still be more than enough power. 1/10 scale nitro stadium trucks originally used .12's and later with RTR's .15's and those boogied, the HPI Nitro RS4 MT had a .15 and that thing got down! (it was also 4wd) even with a little larger (longer) size of a short course truck it should still be more than enough. short course trucks don't weigh that much more than an old stadium truck but the wheels/tires are less weight cause they're narrower. so rotating mass is, at least in theory, lower making it easier to push.
if you're overly concerned about power maybe look into the HPI 3.0 engine. i believe it's a .18. i have one of those in an HPI Nitro RS4 2 touring car. that car originally had a Nitro Star .15 and the 3.0 is noticeably more powerful. ...goes through fuel noticeably quicker to...(drains the tank about 2 min faster)
