Well if you want more power and better run time. I would go with some better batteries. I think a set of ib 3800 or gp 3700 would give you more punch and longer runtime. You can get the metal gears from mike( owner of this fine forum) If you not breaking nothing it is no need in adding weight to driveline though. welcome to the forum to. I am new at the pede thing as well. I have been thrashing some bigger brushless around though.
