8. Centre of Gravity
Check that all control surfaces are centred and responding correctly to transmitter inputs. Adjustments
can be made to control surface centres by carefully rotating the plastic control horns on the threaded
portion of the metal control rods. Use the servo reversing function on your transmitter for any control
that is not responding in the correct sense to control inputs. Make certain that all plastic links are
securely “snapped” closed and that all control surface hinges are secure.
It is vital that you check that the centre of
gravity is correct. Failure to do so could result
in a complete loss of control. We recommend
the balance point of the model, complete
with batteries, should be 125 - 135mm back
from the leading edge of the wing for initial
flights, (image 27).
Note: Depending on the
batteries used, it may be necessary to add
weight to achieve the correct C of G.
We make the following recommendations for control surface deflections. Experienced pilots
may wish to increase these movements after initial flight testing.
Ailerons:
10mm each way.
Elevator:
10mm each way.
Rudder:
12mm each way.
Flaps:
30 Degrees.
