Sc10/slash questions

[DaveG28]

Possibly looking at one of these as bashers, and have a few questions:

1. Can you get cheap stick trannys that work with the receivers included (does sc10 include one?)

2. What's the best batterys for each?

3. Is the sc10 quick enough standard? Just asking as it comes with a 17t motor, whereas the slash has a larger 12turn.

4. How waterproof is the waterproof slash? Is it safe to run in the wet?

Just looking at "box stock". By the way, would an old tp3200 saddle (not the brca legal one so longer) fit in either?

Cheers!
