XRAY - Model racing cars

ok, the motor im using a motor that is as old as the hills and its time to get a new one.
what brand are you using and why would i buy that one over another brand? (must be 27t)

i'd highly recommend a trinity co27 pro

For overall speed and performance, you can't really beat the CO27.

The original Monster has been the best for me when it came to lower cost, less maintenance (more runs between comm cuts and new brushes) and a bit wider gearing range.

And last but not least, the P2K2 isn't a bad choice if you have a dyno and know how to tune it and gear it. Especially if the track layout has more than one slow tight corner.

my new co2 is fast, thanks guys i love it

motor was run-in, oiled after each race,
but how long should it last before i need to open it up for com cut and new set of brushes?
i think i have a problem with it now, it want really slow in my final.
