Sorry about the "chick car" comparison, I was thinking 300Z or somthing like that, but didn't think it deserved THAT much credit lol. It's a small and fun, but it's no corvette,
atleast not in Utah.(4500ft) at sea level, a C-1 might actually have some nuts...
As far as the slips go, The best way I have seen it done in a Katana was to go back and forth from left to right, since once established in the slip it doesn't create that much drag. (probably not the best technique to teach a beginner) And it doesn't matter how many degrees of flaps you have in, with the Katana it's not going to start to drop until you get it under 75kts. Full flaps just let's you point it at the ground while keepin it slow....
