introducing game changing performance!

On August 1, 2017, Airframes Alaska dotted the i's and crossed the t's on a deal to buy Performance STOL, creators of experimental and certified double-slotted flaps for Cubs and Cub-type aircraft. Over those first weeks in August we moved manufacturing up from Oregon and set up flap production at our hangars at Birchwood Airport. We are still moving and growing, since November 2019, we are now in our new manufacturing facility at 81 E Commercial Drive, Palmer, AK 99645 and operate under one roof for the entire company.

Certified Flaps

STC'd for PA-18s, certified Performance STOL flaps are a 66" direct replacement for OEM Piper Cub flaps extended to the fuselage. The current lead time for new certified orders is four months. View installation instructions here.


Experimental flaps

$6600 2-Hanger | $7600 3-Hanger | $8650 4-Hanger
Experimental Performance STOL flaps are custom built for Backcountry Super Cubs, Javron Super Cubs, and other Cub-type experimentals.


Why Performance stol flaps?

reduced stall speed

Pilots see an average 4 to 5 MPH reduction in stall speed depending on the conditions. That means slower, shorter landings and takeoffs.

improved nose visibility

With PSTOL flaps deployed, lower airspeed does not equal a higher angle of attack. Pilots fly at a flatter deck angle without increasing their airspeed.

Increased safety margin

Safety is the bottom line. You fly slower, land and take off shorter, and (most importantly) see where you're going while you're doing it.
