I've only been playing with model Heli, boat, car and plane engines for 42 years.

I think Houston is on the money with rich settings causing wear as the oil is diluted due to excessive methanol/nitro present when running rich so wear has to be faster imo.
Ive seen it a hundred times over smelly , rich lsn especially , that is 99% of the time the cause of front bearings seal being compromised and letting dirt get sucked back as pressures change in the crankcase

I mean dont get me wrong , if your track surface or area you bash in is super dusty and fine dirt its pretty dam hard to keep from having to change front bearings often

Its no coincidence that every time i pull my engines down for inspection that the front bearing is very clean and dry on the outside , but i do use either byrons race 3000 or pro driver 3000 which has a fair amount of castor and i keep my lsn pretty lean , i also get exceptional runtime and have a very driveable car
