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 |
Hello Julien
Try posting on the Diamond Aviators Website. Lots of useful Diamond information there DIAMOND AVIATORS NET, the forum for Aviators of Diamond Aircraft DA20, DA40 and DA42 Good luck JERR |
They may be towards the wingtip to induce a wing drop for training purposes. Some aircraft are inherently stable during a stall.

Thanks Jerr for the link. Great forum !

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. Cheers, O8 |

The real DA - 20 was the Falcon 20, a delight to fly.
