LOL, they're the same all the HSP cars are the same, the parts are the same, the quality is the same an HSP car is an HSP car and that's the bottom line. We sell both himoto and Redcat HSP parts mixed in our store only because we buy from whoever gives us the best price and so on at the time when we buy, LOL. There's no difference. They both sell the HSP and they BOTH sell the Non-HSP (mega-p for himoto and the new stuff, like the earthquake for Redcat) ALLTHOUGH, there is a difference in these cars, Redcat uses the lower quality hard nylon and Himoto uses the Higher quality Poly Carbonate nylon(flexible, like RPM parts). The parts DO NOT all interchange, since the lowwer quality hard nylon has to be thicker to hold up to the abuse and the Mega-p parts are thinner since they are made out of polycarbonate nylon and can take the abuse because they flex instead of breaking. I'm not about to argue with anyone about which is better, they have there ups and downs. I've seen them both, sold them both and used them both. We also carry parts for them both.
