This works awesome! I wish there was a little more information on making a shift servo work, as I am newer to the RC world. This transmission is so intricate with 17 gears on the inside, it amazes me. I was able to get the traxxas brushless motor working with this by sanding the brass pinion down and the results are awesome. I wish low was just a little bit taller for more wheel speed but it will climb a wall with this ratio. I told everyone I know with one about the versatility and performance. I ended up ordering 3 more!
