Stall strips DA20
Hi all,
I have a question regarding the stall strips of the DA20.
If my sources are correct, their primary use is to encourage the stall where they are mounted.
Besides this, they also create a buffet near the stall which can be felt through the control colums.
Now my question is, why are they mounted close to the wingtip on the DA20 rather than wingroot ? Wouldn't it be preferable, to enhance the stall characteristics of the aircraft to have them mounted close to the wingroot ?
Best regards,
Julien

Is the DA20 a T tail? Maybe it's to ensure a wing drop at the stall rather than having the tail "blanketed" at higher angles of attack with the possibility of loss of elevator control.

Hi Julien,
Having instructed in Diamond aircraft for years, I think they are in that location for three purposes. They offer some buffet over the aileron for pilot's stall indicator purposes. They guarantee aileron effectiveness right up to the stall by converting a laminar boundary layer into a turbulent boundary layer. They modify the spin characteristics of the aircraft to make it still a good spinner, but consistent and safely so.
