The Horton STOL
Conversion will give the advantage of taking-off and landing at a
slower speed, the ability to get out of grass strips easier, obtain
better performance at high altitudes, with better aileron control at
low speeds, reduce the tendency to spin and reduce the stall speed.
The slow landing performance is not your main concern but safety is.
The Horton STOL conversion will provide that extra margin of safety.
In the event of an engine failure and you are forced to land in an
unfamiliar area, the STOL conversion gives you more time and control
of your airplane by allowing you to reduce forward airspeed, while
reducing the sink rate.
The combination of these results will give you the possibility of
touching down at a fraction of the normal speed, the chances of
personal injury and aircraft damage is greatly reduced.
Your aircraft will be modified with only the necessary and approved
items to improve take-off, slow flight and landing characteristics.
Only STC's and certified materials and quality parts are used in the
Horton STOL conversions. The FAA has issued a Parts Manufacturing
Approval (PMA) to Horton STOL-Craft for the production of our STOL
Wing Foil Modification
Very important is the addition of a special leading edge which
increases the leading edge profile. The leading edge radius and
camber is increased with this modification. Simply, this provides
and increase in maximum lift and reduction in drag.
For the owners of new Cessna aircraft with the Camber Lift Cuff,
HORTON STOL-CRAFT has designed and engineered a new leading edge,
for increased performance, to replace the Cessna Camber Lift Leading
Conical Cambered Wing Tips
Low speed aileron effectiveness is improved by special wing tips.
Induced drag is further reduced since the HORTON STOL-CRAFT tips
reduce wing tip vortex strength. They also increase the wing area
and decrease the stall speed.
Control Surface Seals
Not readily visible in a complete conversion, but very important are
the control surface seals, also known as gap seals.
The control surfaces of most conventional aircraft permit air flow
from the underside of the wing where the high pressure area is
present to the upper portion where the low pressure area is
developed. The air "leaks" through the space between the ailerons
and the fixed position of the wing. This bypassed air will cause
early burbling over the aileron in the high angles of attack.
We install a strip of aluminum in this gap between the wing and
aileron to prevent or greatly reduce this unwanted movement of air.
As you recall from your flight training days, modern general
aviation aircraft are designed in such a manner that the stall
starts at the inboard portion of the wing and then moves outwards as
the angle of attack is increased.
The HORTON STOL-CRAFT stall fence controls the stall span wise
progression and therefore maintains longer aileron effectiveness
through higher angles of attack.
As a result, the low speed handling qualities of the aircraft are
greatly enhanced, and then lower portions of the wing, depending on
the aircraft manufacturer.
