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)...

hehe no i don't have video but it's true.

I think cnc delrin spur gear will be better?

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.

what are you running it on? 4s. if so go down to a 3s or just run your 2s in parallel
