gasshead, welcome to the forums!

Although I don't have a Revo, I had done a couple of truck conversions. Are you planning on staying with 12 cells? As a general rule, I'd stay away from the "L" can motors, especially for trucks. They tend to run hot. All Feigao motors are going to get hot sooner or later, but the L's do it sooner than later. If you are going with a Feigao motor, try to stick with the "XL" can motors.

Since it seems that you have a limited budget, there are a couple of things that I can suggest, and this is taking into consideration that the MMM is not out yet.

If you are going to stay with 12 cells, I'd go with a 7XL and a Mamba Max speed controller and external bec.

A better way to do it would be to bump up to either 14 cells or 4S lipo and go with an 8XL and the Mamba Max speed controller with an external bec.

If you got your idea of using the 8L from that mag article, that's fine; but many here have found that the L can motors just plain get too hot for extended running and have gone to the XL can motors. I, too, started out with the 8L, but that didn't last long. The XL can motors have more torque and can take more gearing. You'll be much better off with an XL can motor in a truck.

The Mamba Max speed controller, although only rated for 12 cells or 3S lipo, does very well on 14 cells or 4S lipo. You just have to use an external bec or battery pack to power the electronics. I have five Mamba Max escs and have never run any of them on less than 4S lipo. The only trouble that I had with any of them was when I tried to run them on 5S lipo.

Good luck with the mod.
