RE: Tamiya FineSpec + Unidentified Buggy
thats the best thing for the car, a kid.
you could go brushless, but it will be alot faster and flip over alot. that suspension is very limited.
i suggest a pair of new tamiya sport tuned motors. they are a little faster then stock and last a long time.
if you really want to try brushless go for an ezrun 35amp, 13t combo. it's pretty mild, but faster then stock.
the popular 9t ezrun is just too fast for that car, it would be like a rocket.
"what batt would i recommend?", that depends on what kind of charger you have, and what motor system you end up going with.
if you need a charge then you might as well use lipo batteries, but if you already have a charger a decent 6cell nimh batt will be fine.
first thing you need to do is take it all apart and install bearings.
