1.5d in an lst2 is a retaded idea rofl no way it can take it on 6s..Im doing the same to my emaxx (close to same weight) I can fit 62/25 with 1/8th gears on my 1.5d on 6s and thats about 55mph maxed LOL... I dont like that motor, I hope it blows up. Ive seen Stumblin roll his revo 70mph on a 1.5d on 6s but it didnt live alot longer
I ran a 1515 1.5d in a revo on 4s. Geared for 42mph it would pull a set of trakpower hc lipos a bit hard. As long as you have good lipos the motor will be fine. I expect you will easily pull 120amps, so hopefully the MMM can keep up. A 1515 1y may be a better choice for 6s... I plan to run the 1515 2d that I have coming on 5s... No real need to spin it much faster for the stretched savage...
