Descent Rate – QUIK at MAUW 409kg
With the reflex trimmer set slow, the minimum sink rate is approximately 600fpm at 53mph (85km/h,46kn)
With the electric trimmer set slow, the minimum sink rate is approximately 490fpm at 45mph (72km/h,39kn)
At 65mph the sink rate for both systems is similar, approximately 850fpm.
Descent Rate – QUIK GT450 at MAUW 450kg
Fully loaded, the engine-off sink rate is around 517 fpm at 47 mph (75km/h, 41kn) and increases as speed is
increased. Best glide angle is 8:1 at 47mph (1.3 nautical miles/1000 ft in still air)
Pitch
Whether flown solo or dual, pitch control is very smooth and positive, progressive and damped, providing
good "feel" at all times and in all manoeuvres. Pitch control is lighter when flown solo than dual. Pitch control
force is also affected by the trimmer; heavier in the slow trim setting than the fast. If caught out in turbulent
conditions, set trim to take-off to give more pitch feel.
Roll Control and Turns
At normal cruising speeds of 50 - 55 mph upwards, turns may be initiated by simply moving the control bar to
the side away from the required direction of turn. As the turn develops, the control bar should be eased out
to maintain the desired airspeed. As the desired bank angle is reached, the turn control input should be
relaxed. Increasing bank angles requires increasing bar-out pitch control forces to coordinate the turn. Roll
control becomes slower at low airspeeds, so the bar should be pulled in slightly to increase airspeed before
commencing the turn. For roll-out the control bar is moved towards the lower wing tip, and the nose is
lowered as the horizon levels. When the aircraft is flown solo, the roll response is faster for the same control
force. Roll response is also less damped especially at high speeds in excess of 65mph. Small control inputs
should be used. Co-ordinated turns can be achieved with a maximum bar movement of 3 inches.
Trim – Longitudinal
The aircraft should be set at the desired steady speed/attitude/power and then the trimmer operated to
remove the pilot's pitch force on the control bar.
Trim for takeoff at the placarded position on the indicator, 60-65mph. When established in the climb, trim
back for maximum rate of climb 55mph. For landing approach, trim at 55mph solo, 60mph dual.
CLIMBING
DESCENDING
Trim – Lateral
When criusing, the nosewheel can be used as a rudder to trim out mild turns or to provide mild
course corrections. RIGHT nosewheel steering gives a RIGHT yaw which creates a slow LEFT
hand turn. The effect is most noticeable above 70mph. The wing should be tuned straight enough
to be turned slowly each way by this method.
Effect of Power Adjustment on Pitch
As the thrust line is set low, the effect of reducing power is to lower the nose of the trike, and an increase in
power will cause it to rise. The wing will continue to trim at a similar airspeed, power on or off.
