The Cozy Mark IV is
in a class by itself. It is the most popular plans-built,
high-performance, 4-place. Its safety record is unexcelled. Building
cost at $15,000 for the airframe is about one-half that of prefab
4-place designs, and building time is about the same. With a useful
load of 1000 lbs. a range of over 1000 miles, and a speed of over
200 mph, it has equal or better performance and utility than
factory-builts costing $250,000 and more. The Cozy Mark IV plans and
instructions are the most detailed and complete of any design on the
market, and builder support is unequalled.
The Cozy Mark IV has
the reputation of the most thoroughly flight-tested experimental
design. Aft c.g. flight testing was done by ex NASA test pilot James
Patton, and reported in April '94 Sport Aviation. He concluded that
a Cozy Mark IV, built according to plans and operated in the
approved c.g. range, has excellent stall resistance.
Ed Kolano, test
pilot for Sport Aviation, gave an excellent evaluation of the Cozy's
flying qualities in November '98 Sport Aviation. He concluded, "It
is comfortable and boasts impressive performance numbers. It has
benign stall characteristics and positive dynamic stability and it
is easy to fly."
Foundation's excellent evaluation of the Cozy's performance was
reported in April '99 Sport Aviation. It concluded, "Its cross
country efficiency places it among the top homebuilts in its class."

back in 1982, and is the only such design licensed by Burt Rutan.
