So as you know, if the stall begins out at the wingtips, we'll see a wing drop (often violently and no way to control that during landing). But if the stall begins at the wing root, all we get is a nose drop, with the plane still under some control.
Adding stall strips will cause the plane to stall at root instead of tips on this particular bad design plane.
What you want to happen and the way you describe it working isn't what's going to happen or the way it's going to work. A number of people tried to expain that in the other thread you started.

A stall that begins at the root or at the tip will cause one wing to drop if only one wing stalls. It doesn't matter where the stall starts, the nose isn't going to droop unless both wings stall at the same time. And when the stall is instigated by the usual newbie practice of steering the takeoff or landing with the ailerons, most probably only one wing is going to stall.



So my question to those who are expert is where I should add the stall strip, and how long should be the stall strip. Of course I wuld think to eliminate stall is a skill level here.

And the answer from some of the experts is not to bother with the stall strip. Fly the airplane with a couple of clicks more throttle on landing. Take it off without SLAMMING the throttle to full. Ease the throttle and by steer with the rudder.

But since you're insistent and think stall strips are going to make the airplane stay under control in a stall, the Corsair used a stall strip on some aircraft. It was probably about 5" or 6" long on the full scale Corsairs. They had a wing span of roughly 41feet. It was placed just outboard the guns on the starboard wing only so it was roughly 1/3 the halfspan outboard. It was also not installed on some of the later aircraft as it's effectiveness was questioned.

Steer your landings and takeoffs with the rudder and land with just a touch more throttle.

So all this boils down to why the Chipmunk is not the most popular in the nest eh? I see the planes from time to time but nothing serious.
