Not to rain on your parade also, but how would you even upgrade that? i mean the only way i can see would be to get a complete new mechbox. or at least a couple parts at a time. I mean i can see buying a new motor only to have it shred through the other stock internals. Ok so we'll start with the gears then. the stock motor shreds it's own pinion gear on the hardened gears. so we'll start with the spring. the power of the spring destroys everything else. etc. i mean what you are trying to do is possible i suppose but it doesn't seem very good to me, sorry
