I have owned the equivalent Peak Performance motor called the Dynasty. These are exactly the same motor just under different labels.
The motor out of the box is very torquey. Really great motor for truck or 4wd touring but won't have as much top end as other motors.
My configuration I ran it with in stadium truck ( T4 ) was reedy 767 brushes all around and purple springs on the positive, red on the negative. You can also try running the 766 brush instead all around or just on the negative side to get less wear.
If you haven't bought a motor yet, you may want to look into the Reedy 19T Quad Mag motor. I have this motor, and it probably is the bet 19T motor out there now. My LHS owner usually runs the Dynasty in touring and I lent it to him, and after doing alittle gearing adjustment ( this motor is geared very different than other 19T motors ) he was really impressed, and it takes a lot to impress him.
you can get this motor at www.roadragehobbies.com
for $34.99 shipped. It may not be listed but email them and they do have it. This is where I got my motor from. Make sure to configure it the same way as I mentioned for the Dynasty.
One thing, if you are going to get this motor, you will have to gear differently than you would with a normal 19T motor. so lets say you have a T4 and it is recommended to start at 19 tooth pinion for gearing, you should actually start about 2 teeth higher than the stock motor gearing recommendation, so about a 22 tooth and you may even want to go up even more. My LHS owner actually went up 8 teeth on his touring car ( 64 pitch pinions ) to get the right gearing.
So, I say get the Quad Mag, if not, the Dynasty / Element is the next best choice.
