idea to connect 100 mm servo extension leads to sockets 2 and 5 permanently, as
this makes it much easier to connect the aileron servos when you rig the aeroplane.
At this point you should carry out a check of all the working systems, with the RC
system transmitter switched on. Please bear in mind that the motor could burst into
life when you first connect the BEC plug and socket, so remember to remove the pro-
peller before switching on for the first time.
Control surface travels
The following control surface travels are our recommended starting point, but you
may wish to adjust them to suit your personal preference: ailerons 16 mm up and 8
mm down; elevators 15 mm to both sides of neutral; rudder 22 mm to both sides.
Balancing
Assemble the model completely, ready to fly, i.e. with the LiPo flight battery in place.
The Centre of Gravity range is 60 mm to 70 mm aft of the wing root leading edge,
measured at the centre of the wing. You can set the correct CG by adjusting the
position of the LiPo battery. Support the model at the stated CG position with two
fingers under the wing roots, and allow it to hang freely: when balanced correctly, the
fuselage will hang level.
Flying
For the initial test-flight wait for a day with very little or no wind, and assemble the
model completely. Check that all control surfaces are at neutral. For a successful
take-off from the ground a smooth, level strip pointing directly into wind is ideal. If
your runway is not of that quality, switch the motor on, and give the aeroplane a
hand-launch directly into any breeze; trotting forward for a few steps gains the neces-
sary momentum. Initially use the aileron and elevator controls gently, just to correct
any deviations from a straight flight path. Fine-tuning can be carried out by adjusting
the trim sliders situated below and adjacent to the transmitter sticks. Always land the
model directly into wind, with the motor throttled back. Just before touch-down, apply
slight up-elevator to flare out and slow the machine down further. It is essential al-
ways to land straight into wind.
All of us at GRAUPNER Modellbau wish you many fine flights with your new
