In a 2wd the gyro can work for both acceleration & braking. With my Rustler I found that under acceleration if I lost rear wheel traction the way I had the gyro set up it made the situation worse & the steering started hunting (over correcting) & fighting itself to the point where the gyro had more control than I did even after I'd returned the TX to neutral...under braking however if I was running straight & the gyro was reduced a little from the point where it would hunt under acceleration, I could brake to a slow stop without any concern that I 'd loose control. Over 80, I find stopping a 2wd hard without some help

In a 4wd, if you use a gyro, I'd suggest adjusting the gain to aid braking. It just lessens the stopping worry & gives a bit more confidence to push harder under acceleration...but they're not as important in 4wd IMO

Sorry for the long winded answer

Stopping is something worth considering also. You want to stop slowly from 80+, I use about 15% drag & 30% brakes. Once you're not accelerating the drag settles the car momentarily before you start braking, I'm only talking half a second or so. I found this suits my style very well...I can't accelerate & then brake from that sort of speed easily, I just spin, so a very brief pause works for me. If you go mechanical brakes they obviously work as well as they're tuned but to replicate the same progressive feel takes more than adjusting the ESC but it's worth spending that setup time because hitting the anchors over 80 really unsettles the car
