It should do fine with a low rollout.

Through google I found the Viper 1/8 motor webpage. The rotor size is listed as 13.8mm.

Nice, looks like it will be completely user rebuildable like the 1/10 Vipers. Would be nice to have one motor and then be able to buy a different stator if you wanted higher/lower kv.

Higher kv's would be nice too.

Novak also has the 1/8 motors coming. 8 and 8L versions, 1.5y and 1y

Took 'em long enough to make a real 1/8 motor- no mention of kv ratings though..

I see they are also making a compatible 1/8 esc ( again, very late into the game ), but limited to 4s? Hmm...

The 4s is the let down. I wonder if they will put gearing limits too.

I guess that explains why the SC8e has a Castle Combo, not the LRP Combo in there.

Yeah, I would guess lots of burned up motors and speedos, and too much complaints and warranty claims. They did have a RTR (or maybe they called it "combo" version) of the SC8e with the LRP system for awhile, but it only lasted a short time before they discontinued it.

80931-25 — SC8e/SPX8/Vector 8 2500Kv *Discontinued*
80931-28 — SC8e/SPX8/Vector 8 2800Kv *Discontinued*

That said, I am going to try out the Vector 8 motor in my on-road GT, but it's a different application (small wheels, low rollout) than 1/8 SC, and I know how to gear a vehicle properly. Even then I'm unsure if the results will be acceptable. So I can imagine someone throwing in 6S with the 2800kv in the SC8 with stock gearing would be in for some big problems.
