oscillate mildly in pitch after full aft stick is reached. This is a
mild "bucking" of very low amplitude, one to two degrees and
about one-half to one "bucks" per second. If the full aft stick
is relieved slightly, the bucking stops.
3) Occasionally, particularly at aft c.g., the airplane will exhibit
an un-commanded Dutch-roll, a rocking back and forth of the
wings in roll. The rock, if it exists, will be mild and
some-times divergent, reaching a large roll (30 deg. bank) by
about the fourth or fifth cycle. The "wing rock" should be
stopped immediately by relaxing off the full aft stick stop.
Prolonged wing rock can result in an uncontrolled roll-off and
altitude loss.
At any time during the "stall" power can be set at any position, or
slammed to full or idle, without affecting the stall characteristics.
There is a small roll trim change due to power and very slight
pitch trim change, neither affect the aircraft's controllability at
sustained full aft stick.
Accelerated stalls to 3-g and steep pull-ups to 60 degrees pitch
(min. speed, 55 knots) can be done at full aft stick without
departure tendency.
Intentional spins have been attempted by holding full aft stick
and using full rudder, with all combinations of aileron control, and
at all c.g. positions. These controls were held through 360
degrees of rotation. Full aft stick and full pull-up results in a lazy
spiral which ends up in a steep rolling dive at 3+ gs and 100
knots. At any time, the spiral can be immediately stopped by
removing rudder control and a completely straight forward
recovery can be made. That maneuver is not a spin, since at no
time is the aircraft departed from controlled flight. If the above
maneuver is done at aft c.g., the rotation rate is higher so the
lazy spiral is more of a slow snap roll. However, even at aft c.g.
the recovery is immediate when controls are neutralized.
You are cleared to do stalls in your COZY in any power, trim or
landing condition within the normal operations envelope.
Intentional spins (or attempts to spin) are not approved.
NOTE
Experience with other aircraft of similar configuration (VariEze,
etc.) has shown that some variation in stall characteristics may
be expected from one airplane to another. Inaccurate airfoil
shapes, incidence errors, or weight and balance errors can result
in a degradation of the normal safe stall characteristics. Aft of the
