I've got about 10 hours in a katana and the only thing in common is the
differential braking... Quickie will challenge your guts, make you a better
pilot, and either you'll love it or hate it! Flying a Q isn't the challenge,
but taking off at much higher speeds and landing at mach 9 will give you a
reason to go to church! Go fly with someone (more than once preferably) first,
think it over, and make your decision...
