This is 1/10th scale, the sc8e isn't (and I have one... actually a converted rc8t eh)... so that tosses the sc8e out. Being that the slayer was built for a heavier nitro engine, it probably weighs more the the 4x4 slash even in converted form. And the fact to race electric 4x4 SCTs you'd have to do a conversion, this is out of the box electric and 4x4... so right there plenty of good reasons.

I don't see why anyone would want this over an e-converted slayer or an sc8e
