Yes, use the lowest gearing possible at start. Check temps, but i think you will be able to gear up to 40mph without issue on 6S, the mamba monster can handle lot of power.

My 2cents, I'm running a 1717 in my XXL and it's a real handful. The torque twist makes it pull REALLY hard to the right when theres ever any kind of traction even with the LST tranny design. The truck is nearly undrivable on the street if you want to drive anything more than bumper car fast. I wonder if the 1520 might have ben a better choice for my application ?
When off road and theres limited traction, it makes up for itself with the crazy low end and efficentcy tho.

So I guess the 1717 would be way to much for an E-Revo?? I was thinking the 1717 or the 1520. I dont want speed just gobs of torque. Im running my Revo with (I believe)LST-2 tires(the big ones). I have a small track(area) @ my dads and just do a lot of bashing. Id like to not have to worry about overheating.

a castle 2200kv motor would be plenty. as long as you gear it for 35-40mph, there shouldn't be any overheating problems and it will have all the torque you will ever need.:yes:

Agree, 1515 is the perfect motor for the ERevo. I you want to run a higher voltage than 4s just get a lower kv motor than a 2200. Even the Castle 1518 would be nice, it's perfect on 5s. Due to the Erevo's limited strenth anything more would be asking for tons of repairs after every run. I beleive the 1717 pyhsically wouldn't even fit on the mount of the Erevo.

Thanks. I actually didnt even think about the size of that thing. It probably would hit the shocks. :oops: And 40mph is fast enough for me, as I just like to bash. Thanks.
