Why not lock it in first???

I have been racing my buggy on 5s also. Its great as long as you set up the esc with some punch control to help keep everything in line and are running a proper kv motor. I can run a 15 minute main on a 5s 4350mah pack and still have a reasonable runtime safety margin. It rarely even pulls over 50A peaks. The whole system is barely warm after the whole race.

I personally think people that say they are harder on their system racing over bashing are doing something wrong. When I'm bashing i am geared higher and mashing the throttle much harder than when racing. Racing requires control. Bashing is just seeing how hard you can push everything. I am much harder on my motor and esc when bashing IMO.
