Flap / Aileron Gap Seal Kit. Piper Twin Comanche PA-30, PA-39 Models. 30GS

The KNOTS 2U gap seal kit is the most complete and effective on the market. They are made of 2024T-3 Alclad aluminum, and install to look like they were meant to be there from the factory........not an afterthought!. Our kit is the most complete covering the flaps, ailerons and Flap / Fuselage gaps.

Owners report cruise speed increases in the 4-5 mph range with added benefits in lower stall speed (other designs can actually increase stall speeds) better aileron authority, improved climb, quicker roll rate, and improved low speed handling.

The kit comes complete with all hardware, step-by-step instructions, and is fully STCd.

The purpose of a Gap Seal is to create a pressure barrier between the high pressure air on the bottom of the wing and the low pressure air on the top of the wing. The diagram shows how the air moves upward through the gaps, thus causing significant drag and reduced control authority. Another benefit to a Knots 2U Gap Seal is that it smoothes the air traveling along the bottom of the wing, thus further improving airflow. The effects of a good Gap Seal kit will be:
- INCREASED CRUISE SPEED
- IMPROVED RATE OF CLIMB
- CRISPER AILERON AUTHORITY
- REDUCED STALL SPEEDS
- IMPROVED HANDLING CHARACTERISTICS
