yeah, plastic in a transmission is never a good idea for the most part. that's actually why i was shied away from this truck, but now i think i will reconsider.
will that 28t idler work to replace the stock plastic idler? those seem to take the most abuse.
i'm running a brushed trinity cameleon 19t with a 2s lipo it works well for the tracks we built.
the electrix truck is good who you bought it from put it through itds paceses. i own the truck and i have no problem with it at all and it is brushless.
