TOTAL CONCEPT WING TIPS
 
The Crosswinds S.T.O.L. Inc. Total Concept Wing Tips were designed long after the age old argument that wing tips either increase performance or they don't. At Crosswinds we have designed a wing tip that does affect the performance of the following aircraft. The Piper PA-12, PA-14, PA-18 (All Models), PA-20 & PA-22. First off, when we talk about performance we are not just talking slower stall speeds or shorter takeoff rolls. Performance at Crosswinds is about safety, controlling an aircraft at slow speeds when approaching or near stall,  increasing the angle of climb to clear obstacles with out compromising safety and improving cruise speed and efficiency

The Total Concept Wing Tips improve performance using several concepts. First, these wing tips do not droop and have no affect on visibility on the high wing aircraft mentioned above. Second, these wing tips add a large amount of wing area that maintains the same USA 35B MOD airfoil on the top of the wing adding far more lifting surface. Third, this wing tip design helps control wing tip vortices created by induced drag at high angles of attack by channeling air downward and outward toward the trailing edge of the wing. Fourth, the tip uses a wing tip fence that functions like a winglet to reduce vortex disturbance that is responsible for aileron blanketing as disrupted air boils over onto the top of the wing. Reducing this blanketing affect causes the aileron effectiveness to be improved throughout the flight envelope.

The Total Concept Wing Tip is constructed of light weight aluminum, and fiberglass. Minimal fabrication and parts are required.Tips come assembled and are designed to use the original Navigation lights.
 

Crosswinds S.T.O.L. Designed Tail Support

 
At the tail where aircraft take the biggest beating, Crosswinds S.T.O.L. designed the Tail Strut Support.
 
This innovative device improves the strength of the horizontal stabilizer and works in conjunction with the trim system. No 180 H.P. Cub, Cruiser or Pacer should go without this tail beef up modification.

The Crosswinds S.T.O.L. Gross Weight Increase for the Piper PA-12 & PA-14
increase the wheel plane gross weight from 1750 lbs. to 1935 lbs.
 
The conversion requires extensive welding, PA-18 tail feathers, PA-18 landing gear and a minimum of a 150 H.P. engine.
 
 
 

Crosswinds S.T.O.L. 180 H.P. Engine Conversion

The 180 H.P. conversion for the Piper PA-12, Piper PA-14, and Piper PA-18 SuperCub is a complete replacement from the firewall forward using a owner provided Lycoming  0-360 A-2-A engine. The kit includes the following items:

1.    A complete custom built two piece split cowling.

2.    McCauley 1A200/DFA 82 inch 45 degree pitch - fixed pitch propeller.

3.    Dynafocal (swing out) engine mount with rubbers and bolts.

4.    Complete air cleaner with ducking and bracket.

5.    All engine baffling and fasteners.

6.    Carb heat box with advanced heat exchanger and controls.

7.    Rear mounted light weight oil cooler with all lines and mounting accessories.

8.    The complete free flow, low restriction, dual muffler exhaust system; similar to that used on the Cherokee 180.   

Crosswinds S.T.O.L. Inc's 180 H.P. engine conversion offers more than just an increase in horsepower. The Crosswinds S.T.O.L.180 H.P. engine installation is the most extensively proven engine conversion available. The conversion replaces the engine and all the major operating components. Unlike many conversions that bolt on and use many of the poorly designed original components like the SuperCub 150 H.P. exhaust system, longer conical engine mount, and a modified version of the original low visibility engine cowling with its unsightly lowered air intake. Crosswinds S.T.O.L.'s 180 H.P. conversion uses a superior designed shortened dynafocal engine mount. This mount is stronger, adds support for the heavier engine and propeller, and reduces vibration. The shortened dynafocal engine mount allows for the use of the free'er flowing PA-28 exhaust system with duel mufflers which improves performance and dramatically improves exhaust system durability. Another advantage of this exhaust system and the dynafocal engine mount is that is allows the engine to be mounted closer to the firewall insuring proper C.G.. The Crosswinds S.T.O.L. designed split cowling offers greatly improved side and forward (over the nose) visibility and improved aerodynamics. Large gullwing access doors offer improved engine access. These features combined with the Cessna 180 air intake along with the Crosswinds S.T.O.L.'s improved carb heat and airbox allows the 180 H.P. engine to operate at its maximum designed performance capability. This in turn enables the engine to turn the long 82 inch climb propeller at the steeper pitch of 45 degrees improving cruise speed without sacrificing take-off and climb performance.

The  conversion cost approximately $15,000.00 U.S. funds.
