Pshhh... airstair 99's suck! I like the cargo door!
As far as the brake issue, if you flat spot a tire on this thing, YOURE DOING IT WRONG!!! I rarely even touch the brakes on most landings, and if I have a high speed taxiway, I can go all the way to the ramp without brakes. Reverse and beta/ground fine are all you really need on any runway longer than 1500' aaand thats just to stop in the first 60%
(even shorter if you bring her in slow).
Anyone who has any time in a taildragger such as a Cub wont have any problems with these brakes, although I know a lot of people like to test their short field landing technique on ever landing even if they have 2 miles of runway... see it all the time.
