Brakes? Who needs brakes? Brakes are for stopping, and shouldn't you be "going"?
Seriously, it's important to note that if you retain the two speed/mech brakes in the stock Revo tranny, you will NOT have reverse. I'm sure you knew this, but just a FYI...
Quite true Brian! i have a tekno converted revo and think that it is great, but I do miss reverse. There is just something about being able to do a reverse wheely that just does it for me! Mech brakes are great, my aveox/quark combo stays cool, even though it is a bit undersized for the application. I just put a small clip-on heatsink on the motor and mounted the quark directly to the al esc mount, that seems to keep the temps in check!
