Stewarts Hangar 21

The Stewart Wing Tip is the best aftermarket wing tip available for the Piper J3 thru the PA-22 series, metal spare only aircraft.  Performance over the stock tip is greatly enhanced, providing:

• Shorter take-off roll
• Lower stall speeds
• Increased airspeed
• Decreased fuel burn
• Rate of descent decreased in half on the short wing aircraft

Bungee Buddy, the safest shock cord tool on the market, is the ultimate tool for replacing bungees on the Piper PA-20 & PA-22s.  The Bungee Buddy also safely installs bungees on the Piper J3, PA11 & PA18.  All you need is this tool and a vise to safely install your bungee cords.
