Like sschultz is saying - it happens.
When you have a tiny .21 ci engine producing nearly 3 hp and spinning in excess of 40,000 rpm - things can go wrong and things will wear.
A lot of people take these little motors for granted. They run for hours under dusty conditions pulling those revs and putting out that sort of power.
If you scaled that sort of power production per cubic inch up to 1:1 with those sort of revs there is nothing else really like it.
Taking it to the extreme (which no one does of course), you should probably be stripping your motor down after every heat (like an NHRA top fuel or funny car motor).
Comparing one of these little internal combustion engines to an ESC is like comparing chalk with cheese.
If you want racing without the drama of parts replacement or on the hop strip downs and maintenance at the track, then perhaps electric is more suited to your needs. I'm not having a go - just saying.
