    Spur gear striped

    My mini erevo is so powerful it can flip 2 circles on the air. I use lipo and have some questions

    should i reduce the pinion?
    is there a cnc spur gear available?

    many thanks

    If you "reduce" the pinion (put a shorter pinion on) it's going to loose top speed but gain torque.

    As far as a alloy spur i don't recommend it. You want to keep it plastic (spur) as the "weak link" in the drive train. You dont want to be blowing out diffs or drive shafts before the spur goes (although some have with the stock plastic spur)...
    Keep flex'in those forum keyboard muscles.

    Something will break as nitro said. You want the weakest link to be the cheapest and easiest part to replace. If you do put Alum. on it, you had better loosen up the slipper a little bit.
