This is my new baby that I wanted to share with you guys.
One tip for Rody and RB on this motor mount if I may. The mount bracket for the throttle mixer lever is too low and causes binding of the spray bar and then the carb drags resulting in it not opening fully. I modified a T Maxx part shown below to raise the arm and it works perfectly now. When the mixer arm is that low on the collar lever for the carb it torques it instead of pulling it and this is where people are having issues. I also had to dremel the collar lever a bit to clear the return spring and linkage.
If others would like to know more about the carb issues let me know I spent alot of time to get it right with no Jiffy Riggin or ugly

The carb can open fully if you tinker with some things but it seems to do much better and be much smoother with the mixer lever closer to the mixer arm collar.
I tried to set it up with out washers built up under the mixer lever and couldnt get it to work perfectly so I put 3 washers under the mixer lever and it worked much better but the wierd looking screw that holds it is too short. I had to make something and that is what I came up with. A simple mod to the motor mount to raise the bracket area for the mixer lever would be much easier and eliminate the fact that the mixer arm has to be longer with the current stock configuration.
Aside from the carb opening all the way is that the longer mixer arm hits the linkage and spring so it then has to be trimmed down any how so simply raising the mixer lever via a taller bracket would fix all of this.

Curious, If stock revo 3.3 can go ~ 45mph+ out of the box. With same gearing and the TM523 installed, would revo 3.3 go much faster, or by adding TM523 i'm simply getting lot more power through range of speed.
