We have one in our RC18T
and it hauls @$$!! It straight up flies with the BAJA. It works with the stock ESC and is totally rebuildable too. For the price it is an insane motor...much faster than the Super 370.
A Losi PRO motor is also faster than the Super 370, but nowhere near the kind of speed you can reach with the BAJA. Go to www.TeamPlatinumRacing.com/RC18T.html
and check out our setup. It's a great motor with a great pricetag. If you're looking for a great brushed motor the BAJA is your best bet. We haven't tried the Mini Monster from Trinity, but from our experience with the BAJA we wouldn't want anything else...unless it was brushless!
It goes between 20 and 25 depending on where we run it. We haven't had one single problem, and there is little or no decrease in power from when we bought the truck. The only problem we've had relating to the motor is it's too powerful. It's burnt through 2 diffs and an outdrive (Which is repairable with FREE outdrive sleeves from Team Associated...if it wasn't already equipped with them). The diffs are made from cheap plastic, which is disapointing because there aren't any manufacturers who produce any metal ones yet. As soon as they come out we will be first in line to pick some up. Our 18T is actually sitting at TPR:HQ right now for a thourough cleaning and rebuild. We were repairing the diffs and decided to rebuild the entire car.
