BOOKS
It is simply amazing what you can find at a library or book store.
But really, for me, it was growing up around cars/trucks. There has always been a project going on, from as far back as I can remeber. Grew up in hotrods and circle track stuff, so I just applied what I learned there to this....Lots of magizines, lots of going to all kinds of races, hangin in the pits, asking questions, and then working in shops. Randy taught me A LOT, only second to my Dad.
Building crawlers is interesting to me because in takes from all other forms of motorsports and pushes it to the nth degree. Sure, offroad racers have huge travel, but articulation is not as important, drag racers have to plant the tires for a good launch, but they only need a few inches of travel, so short arms work. Horsepower=cubes, but in "our" world cubes=wieght....
There are just so many variables that are impossible to have all perfect, that I love the balancing game and to see who the give+take turns out in each vehicle. Thats what keeps me interested and what feeds the desire for new projects....
