Section 26: Preflight Check And Safety - Model Tech Magic Formula 3D ARF Manual

FLAPERON AND SPOILERON MIXING:
Plugging the servos separately into the receiver (one into channel 1 and one into channel 6) will allow the use of flaperons (both
ailerons down at the same time) and spoilerons (both ailerons up at the same time). These functions can then be mixed with the
elevator for extreme pitch changes (high-alpha) useful in extreme 3D aerobatic maneuvers. These recommendations are for
3D flying only.

IMPORTANT We do not recommend using flaperon and spoileron with elevator mixing during general flying, especially
during takeoff and landing.
ADDING TAIL BRACES:
The construction of the Magic Formula 3D is very strong; however, if you wish to add tail bracing (flying wires) to the horizontal and
vertical stabilizers, we have provided hardpoints to mount them.

SECTION 26: PREFLIGHT CHECK AND SAFETY

Completely charge the transmitter and receiver batteries before your first day of flying.
Check every bolt and every glue joint in the airplane to ensure that everything is tight and well-bonded. This should
include all of the control surface hinges as well.
Double-check that you've installed and tightened all of the servo horn retaining screws.
Double-check that the receiver and battery pack are properly secured into the fuselage. There's nothing worse than the
battery pack coming loose during a violent aerobatic maneuver.
Double-check that the fuel tank is properly secured into the fuselage.
Double-check the balance of the airplane. Do this with the fuel tank EMPTY.
Check the control surfaces. They should all move in the correct direction and not bind.
Make sure that you've installed 1/4" long pieces of clear tubing over the clevises and snap-keepers to prevent any chance of
them opening during flight.
If your radio transmitter is equipped with dual rate switches, double-check that they are on the low-rate setting for your first
few flights.
Check to ensure that all of the control surfaces are moving the proper amount in both low and high rate settings.
Check the receiver antenna. It should be fully extended and not coiled up inside the fuselage. Do not cut the receiver antenna
shorter or the range of your radio control system will be greatly reduced.
Properly balance the propeller. A propeller that is out of balance will cause excessive vibration, which could lead to engine
and/or airframe failure, and it will reduce engine efficiency and power.
