I doubt anyone who knows about the SC8 from Associated would chime in in fear of losing their job, but it's been claimed that people can see a gas tank in the opening behind the front wheel well. I don't see it personally, but I'm losing hope of it being eletctic. A brushless/lipo ready 1/8th 4WD would be what I'm looking for... Chances are slim IMO it'll be that way though.
If it was nitro I don't think you'd be completely left out. I see many 1/8 scale buggy brushless conversion kits out there. Perhaps a company would make one for the SC8. In fact it probably is based on Associated's gas buggy. (look at the wheels nuts on the SC8 those look like 1/8 scale buggy wheel nuts). So a conversion that would work for it might already be out.
