AimAim To understand how each To understand how each control effects the aircraft control effects the aircraft
in flightin flight
The flight path can be resolved The flight path can be resolved into three planes of movementinto three planes of movement
ControlControl Weight shiftWeight shift
Primary Control is Primary Control is effected by moving the effected by moving the trike unit and hence the trike unit and hence the centre of gravity. centre of gravity. relative to the wingrelative to the wing
StabilityStability HANDS OFF TRIM POSITION- H.O.THANDS OFF TRIM POSITION- H.O.T..
The aircraft is very stable and can The aircraft is very stable and can flown hands off the control bar. The flown hands off the control bar. The aircraft will automatically correct for aircraft will automatically correct for small disturbances in light turbulence small disturbances in light turbulence in pitch and to lesser degree in rolein pitch and to lesser degree in role..

Effects of powerEffects of powerThe initial effect of increases in power
Is a temporary increase in airspeed
Initial effect of reducing power is
A temporary reduction of airspeed
