Motor choice rc10t2

[Sneeck]

Yes I talked to Serum last night and he said even a 8s is overkill in such a small car. Beside's that the 9l is just to heavy. So i'm looking for something else. The 5300 lehner has come up to my mind, if I can be sure the cvd's will hold.(trying to avoid ordering a set everytime I smash the throttle)

The diff gear and top gear are indeed steel. There's a plastic idler's in between. Is it wise to replace it with a steel one? (since metal-on-metal gear's wear fast)

I can only run 8 cell's max, since the charger can only charge 8 cell's.
