I have one of these with a 12TZ in it, Megatech Dark Thunder... thing flies. It's in storage right now, but I would basically just drive it on asphalt. You really need to pay attention to what is actually on the road though, I accidentally hit a small piece of wood at about 60 and exploded the entire front end. It flew a good 20 feet and landed in someones yard, still running but with the pipe popped loose. Fun car though, dragster donuts look pretty intense.
