It would be a bit risky. The xl3100 is a pretty powerful motor and can pull some amps. With conservative gearing and a fan, it would probably work, but I wouldn't do it myself. The xl2800 or below work well with the 7018 controller. If you just tool around and don't really race on a track, you could probably put 14 or 16 cells to the basic 3100 on short gearing and run the he** out of it for a while with little trouble. Put a heatsink on the motor (and a fan wouldn't hurt, either!), gear it with a 12-14 tooth pinion on the stock spur (more cells = lower gearing) and give it a rip. It will work for a while. I ran a 3100 motor for a full season on an e-maxx, but it eventually burned up. I only ran it on 12 cells, though. Higher cell counts with lower gearing probably would have prolonged its life. Of course, this is just advice for the budget oriented guys like yourself. I wouldn't recommend buying this setup new for the e-maxx at all.
