I have spent the last 5 years beefing up the stock transmission in this truck trying to make it hold brushless power, I even went as far as to machine out the diff housing. Well I got sick of replacing parts over the years and decided to swap out a Traxxas full steel VXL transmission. It took a bit of work to get it to fit and work right but it is by far the best mod I have done to it.
Now.......
It uses traxxas driveshafts(had to modify the hubs).
Can handle all the power I wanna throw at it.
But best of all, it looks bone stock.
This truck is now 23 years old but runs like a bat out of hell. Using the same motor, speed control, transmission etc on my stampede I can get 74mph w/11.1v lipo on radar using a brick to keep the front end down. This chassis is lighter and has much better weight balance and center of gravity so I think 85mph shouldnt be a problem just I wont be using the body it took 2 days to paint to try it out.
