The Centre of Gravity range is 60 to 70 mm aft of the wing root leading edge; this can
be achieved by adjusting the position of the LiPo flight battery. Support the model at
the stated CG position with two fingers under the wing roots, and allow it to hang
freely: the fuselage will remain level when balanced correctly.
Flying
Wait for a day with little or no breeze for the initial test-flight. The ideal flying site is a
grassy field with a gentle slope facing into wind. Assemble the model completely, and
check that the control surfaces are exactly at centre before flying.
Switch the motor on and give the aeroplane a hand-launch exactly into any
breeze; trotting forward for a few steps gains the necessary momentum. Initially
use the ailerons and elevator very gently just to correct any deviations from a straight
flight path. Fine-tuning can be carried out by adjusting the trim sliders or buttons
situated below and adjacent to the transmitter sticks. If the model is balanced at the
forward end of the stated CG range, you will need to set about 1 mm of up-trim.
Always land the model directly into wind, with the motor switched off. You can ef-
fectively shorten the model’s landing approach by deploying the airbrake function
(both ailerons deflected up). Just before touch-down, apply slight up-elevator to flare
out and slow the machine down further. Always land directly into wind.
