2. Servo centering and direction: If you fly mode 2, when you pull the right stick toward you, the
trailing edge of the rear elevator and the leading edge of the front elevator should deflect
upwards; push the right stick to the right and the right aileron should deflect upwards and the left
aileron should deflect downwards; push the left stick left and the rudder should deflect to the left
as viewed from the rear of the fuselage.
3. Servo end-point adjustments: If you are using a computer radio, for initial flights set the elevator,
rudder and aileron linkages for near-maximum-possible deflections and use your transmitter to
add some ‘exponential’ to soften the control throws around center. Initial settings if you are using
a non-computer radio:
Recommended Initial Deflections
Front elevator ........................................ +20 degrees (
1/2
-
inch up and down from center
measured at the front edge of the front elevator)
Rear elevator ......................................... +25 degrees (2
1/4-
inches up and down from center
measured at the trailing edge of either rear elevator)
Rudder ...................................................... +22 degrees (1
3/8
-inches left and right from center
measured at the trailing edge of the rudder)
Ailerons .................................................... +13 degrees (1
1/4-
inches up and down from center
measured at the trailing edge of each aileron)
4. Check the Mylar covering material’s joints and surfaces. If necessary, carefully use an iron on
medium heat to secure the edges and to tighten any loosened areas. Recheck and retighten from
time to time; be careful to not apply too much heat as you secure edges or tighten the Mylar. If
any trim becomes loosened, press it down and/or apply clear tape. Never apply heat to any trim,
insignia, marking or plastic part.
5. Ensure the propeller is securely attached to your motor and remains undamaged and correctly
balanced.
6. As with all radio-controlled model airplanes, your Curtiss Pusher must pass the radio-range
ground check recommended by your radio’s manufacturer or you may not fly safely.
VIII. STORAGE, FIELD SETUP & PREFLIGHT CHECKS
1.
Although we do not recommend removing the wings on a model this size, if you need or wish to …
a) Disconnect the wing-wire springs that attach each set upper and lower wing panels to their
center sections. Remove or slice through any tape you may have applied across the joints
where the wing panels meet their center sections. Gently slide the left- and right-side pairs of
wing panels 1 to 2 inches away from their center sections, disconnect the aileron servo
extensions at the root ribs, and pull the wing panels from their wing rods.
b) To reattach the wings, reverse the above procedure. Be careful to reconnect both aileron
servo extensions (and optional Maxford USA servo-extension safety clips, if installed), and
reattach the loose ends of the springs (the ends without the attached wing wires) to all 8 of
their anchor points. Conservative modelers may also apply
3/4
-inch wide transparent tape
across the joints where the wing panels touch their center sections to help secure the wing
panels to their center sections.
2.
Preflight checks:
a) Double-check the security of the motor-mounting box and motor. If installed, ensure your
pilot, any added pilot-body parts and any added nose weight remains secure.
b) Make certain all screws, clevises and other connections throughout the air frame are secure.
c) Double-check the control directions and amount of control throw of the ailerons, elevators,
rudder and throttle.
d) As with all radio-controlled model airplanes, this model must pass the radio range ground
check recommended by your radio’s manufacturer or you may not fly safely.
e) Make certain your transmitter’s throttle is safely set to minimum before turning ON your
transmitter. Carefully operate your radio-control and power system according to the
manufacturer’s instructions.
