Mike, as i tell you at phone yesterday, i'am using a Neu 1515, 2.5d/f, on 6s on my e-revo, and i'am gear 24/62 (because i've the RCM hybrid V2 diff with buggy ratio) to get about 41m/h, and after 15min of hard bashing (road and dirt drag), i've got 148 on my motor, 130 on my MGM 16018 and 95 on the li-po. But i'll change my pinion for a 22T, and drop it to 38m/h. 41m/h is too much speed for my driving style......................................and skill !!!!!!!!!!!!!!!!!!!!!!!!!

So for me, the high voltage on lower Kv motor is the way to go.

Put the 1515, 2y that you bough from me and gear it to be in the 37-39m/h range, and i'am sure you'll be fine.

But you new pack is yet order, so if you ran 6s, do't run it with your 1.5d, put it on the 2y
