I have this case on my salsh and run a Neu 1509 2.5d/s.
So if you use jato MOD0.8 pitch gear you,ll don,t have trouble to run a 1515 in it, BUT, you have to use the smooth can Neu, not the finned one.
And listen to me, you don,t have to put a 1515 in that, my 1509 push my slash like a rocket on 3s, not able to keep the front wheel on the ground
