I have had several Sig kits thru the years and my 4*60 is the plane that goes to the field with me every time I go flying. I've got an LT 40 kit stashed for my grand daughter when she is ready to start building. The coolest plane I've had,(next to my US60), was a Smith Miniplane. I tried to fly that one before I was ready and drove it into a tree at full throttle. That was 15yrs ago. I think it's time I tried again. I've had a Kouger, I didn't really like that kit, the die cutting was awful, looked like it had been stamped out with a butter knife. The Kouger had a date of 2005 on the box. I'm not sure if I should get a new Smith Miniplane or look for an older kit, I really hate messing with a kit that is poorly cut.
