STOL Kits: Bang for the Buck

There’s a good chance that there is some sort of STOL kit for your airplane. It will reduce stall and approach speeds, but is it worth the money?

That’s a Peterson King Katmai-modded Cessna 182 in the environment the modification was made for. It’s a descendant of the Wren 460, which was an airplane with a stunning 27-knot stall speed. The King Katmai has a stall speed that’s 4 knots faster, but, as a tradeoff, has twice the rate of climb and a few hundred pounds more useful load. But if you aren’t ready to put a Katmai in your hangar, Rick Durden’s best-bang-for-the buck aftermarket STOL mod article starting on page 8 covers some good alternatives.

STOL kits for general aviation airplanes have been around for over 60 years because of two favorable circumstances: 1) They work, and 2) Manufacturers could have invested the money to lower the stall speeds of their airplanes, but at some point further improvements become too expensive for the expected demand and they stopped.
