NOTE
• Periodically warm the engine in the descent, particularly in cold and moist conditions.
Because of the great speed range of the Quik and Quik GT450, the aircraft must be trimmed to a reduced
speed for landing in order not to overshoot the runway. If the speed and/or the altitude are too high, make
the decision to go around early. Short field operations should be practiced on a marked section of long
runway first.
The hand throttle should not be used during landing. Trim your approach airspeed down to 60 mph for the
Quik and 55-60 mph for the Quik GT450 and be aware of wind gradient during strong wind days.
The flare is conventional (for a flexwing, but is of course opposite to a 3 axis aircraft), but the light pitch
response can cause over correction and 'ballooning'. Allow the speed to bleed off, and once established in
ground effect gradually push out until the bar contacts the front strut as the main wheels touch. Safeguard
the nosewheel by keeping the bar pushed out until the speed decays and the nosewheel drops. The practice
of immediately pulling the bar in once on the ground puts unnecessary load on the nosewheel and should
only be used in an emergency situation where the available stopping distance is marginal; in normal landings
the wing should be set at a neutral incidence and the brakes used progressively if required.
CAUTION
Locking the brakes can cause tyre damage on
tarmac and snaking on wet grass. If they do
lock, release the pedal immediately and apply
more gently.
Crosswind Landing (see Table in Section 2.1)
The Quik and Quik GT450 copes well with cross-wind landings, but sensible pilots take great care to land
into wind wherever possible. If a crosswind landing is unavoidable, approach at slightly higher speed than
normal, and then bleed off the speed 1 or 2 metres (3 to 6 ft) above the ground where the cross wind is least.
Be ready for the twisting of the Trike unit as soon as the rear wheels touch. Whenever possible utilise
whatever into wind distance you can Pilots should exercise great care in strong crosswind conditions and
should not exceed the limitations in Section 4. Because of the high torsional loads which can be imparted to
the trike pylon and wing keel tube, always carry out a detailed inspection after every cross-wind landing,
especially at the pylon top and bottom fittings.

WARNING
!
Never approach at less than 55mph.
Correct airspeed on finals is of great importance
for engine-off landings. The approach speed
must not be allowed to decay below 55 mph,
and there must be a margin to permit rotation
before touchdown.
