Hey Scott, watching a ton of CrabFu's video's, none of his stuff is underpowered, but it's not as fast as electric powered. The turbine powered tank isn't hurting for power either! How many kid's on skate board's do you want to pull? LOL! If nothing else, it's a nice diversion. I like steam, haven't had time to play lately.
