hey Randy, thanks for the tips.I allready bent the gear to le & installed 3 1/2 tires, in fact there's a supplemetal sheet with the instructions stating just that. I've heard that you have to take off very shallow. I tried to practice this with my sturdybird, but there's not enough prop clearance. As soon as the tail comes up, the prop hits the grass. Soooo.... had to pretty much "jerk" it up. But I'm hoping I can pull it off, the spit has a ton of clearance. So what do I need to do? get the tail up & kinda balance it till it builds enough speed? Thattle take some practice.Any other tips?
