For electric, you take your average run-of-the-mill HPI.
It isn't the best for speed, or w/e.
Say you want speed, you go get aluminum parts, and a brushless motor and esc(the killer part)
For nitro, the starter engines that come with the cars have good speed, for let's say HPI/Traxxas/CEN....
Nitro can go fast out of the box, but if it's one of those knock-offs with no name brands, then you are going to have a lonnggg time modding it.
That's what I've observed, as I own both a 1/10th scale nitro and electric r/c car atm.
