What is the average horse power of these? Just guessing I'd say between 80p and 1,000? They sound ridiculously powered. Really cool. I can't imagine how much it costs to build one. Just something I have been wondering.....has any of them tried building one with all four wheel steer? It seems like that might help in a lot of positions they get themselves into. I don't know though. I'm definitely new to watching. But I'm hooked for sure. Thanks and sorry for writing a book here. Lol.
