I've blown up a few 2 strokes in my time. They do take a little maintenace but they are so much fun. I'll have to put all the clips together in a video at some point. I've got video from all three days and classes.

Wow, those 250cc airplanes sure move and sound like 2 strokes j/k :)I thought a 250cc/150cc race bike would be fun to pick up for the track, then I discovered they cost a lot more than I thought :(
