I hear you, Ironman. To me, the easiest motor to deal with is the BlueTerror.... smooth, dependable, and able to make any project, no matter how poorly engineered, perform well.
Russ kinda touched on an important point when he was discussing all of his old snowmobile parts.... all that extra power kinda forces you to rethink the whole project. I have nothing right now that can handle my Sachs motor (and it's on the low end, by snowmobile standards.), and those gems that Ironman has.... God help us when he gets them things hooked up to the rear wheels of something! Of course where there's a will......
I get the feeling the videos are going to get a bit more thrilling to watch.
