Adjusting the model using the trim controls
The transmitter is fitted with two trim buttons for forward / back control and a trim knob for the
yaw trim (turning left/right).
The forward / back trim buttons affect the control for forward and reverse motion, and for
braking these movements; it is easy to adjust:
Slowly move the left-hand stick forward to the point where the model just begins to lift of the
ground. If it is lifting off front and rear in balance, no trim correction is required; otherwise adjust
the forward / back trim knob carefully until it climbs vertically, without moving forward or back-
ward.
The purpose of the yaw trim knob is to adjust the directional control system so that the model
does not turn to either side when the stick is at the centre position.
To adjust the directional trim, move the left-hand stick forward to the point where the model is
about to lift off. Observe carefully whether it tries to turn to one side or the other, and adjust the
direction trim knob to correct that tendency.
Model turns counter-clockwise
Model turns clockwise
Important: the model can only be expected to fly in a stable manner if it is trimmed accurately.
That is why this settings must be adjusted carefully before you fly the model and repeated
several times during every flight. At the beginning of each flight you should re-check the trim, to
ensure that the model exhibits no tendency (or only a very slight one) to turn or move in a
particular direction.
