Brushless MGT

[_paralyzed_]

gearing for 55 is why you burned the motor. thats way too fast, 40 is about tops for a monster truck, unless you have a huge motor and like 12s. Smaller tires will help. A medusa 80mm motor might be a good option, 6mm less in diameter than a neu. The kb45 would be even worse. Also, you could change just the input shaft on the tranny to the 4.6 input shaft and run the old style slipper (which i've used for brushless and has worked)

otherwise, a cd would be awesome and open up gearing options
