This post is mostly a question for the guys with fast 320s with MKII tails.

My power off stall is usually the first half of a snap roll. Recovery is easy, but it's the ugliest stall I've ever seen. I've heard F-4 pukes complain about this. I've been trying this and that to tame the stall for several years now.

My last attempt was to adjust the flaps down about degree or two from their faired position. NOTE: My faired position may or may not be what Lancair had in mind to be the faired position. I never could figure that out exactly.

So, anyway, I screwed them down a degree or so and went for a flight. The stall numbers are now dead on with Lancairs numbers, and better yet, I can actually fly the thing in a full stall (very busy feet, but no snap). So far so good.

I'd like to get some comparison numbers from a fast 320/360 MKII tail. The angular difference between my main longeron canopy rail and the top inboard surface of my flaps is between 11 and 12 degrees.

The plane has always been a screamer, but now I've got a crappy wood prop on in without a spinner. It's hard to get good data for comparison.

Question 1: If your 320/360MKII tail is fast, what is the angle between the longeron and top of flap at inboard end? I'd really like to know where the flap should be for clean, fast flying. I could live with a crappy stall, but I'm hoping to have my cake and eat it too.

Question 2: If you know where the text book "faired" position is supposed to be, what is the angle between the longeron and top of flap at inboard end with the flap in it's faired position?

Assistance will be greatly appreciated!
