Mini V8 Engines

So I have this miniature model engine that I have been meaning to build for years. Mine does not run on gas like this one does though. See, this one is a real engine. And I guess you put it in small remote control R/C cars. Now I knew there were R/C cars but I had no idea that they got this big and used real gas powered engines. I wish I had the money to buy this kind of stuff because I totally would build minicars all day. Like this one:

Then I guess you can take it to a whole nutha level with the flying R/C models like this helicopter:

And then you can go all the way with you own fighter jets son! I swear! I would be outside with these things all day man!
