Losi LST E-Conversion Kit

[Overdriven]

A 36mm motor will bolt into the Losi mount, the mounting pattern is the same. Your 11xl motor is a older design 2 pole that now a days would be considered marginal depending on how fast you want the truck to go. They're not bad motors, things have just improved so much. The 2 speed does decrease the load on the motor at lower speeds and from a stop decreasing temps somewhat. You also have the advantage of a pretty low Kv and higher voltage improving efficiency and lowering temps also.

If it were me, I'd try it as a single speed with your motor and go from there. Try gearing it for about 40mph or with a pinion that has the same tooth count as first gear. You might have to add a heatsink/fan but that's pretty common for those motors. Some more detailed info on your current setup and future plans will help. Motor Kv, current esc and future, current gearing 1st and 2nd, tire size, etc.
