Top Flite TOPA0155 - Manual (Page 66)

RADIO CONTROL
1. I will have completed a successful radio
equipment ground range check before the first flight
of a new or repaired model.
2. I will not fly my model aircraft in the presence of
spectators until I become a qualified flier, unless
assisted by an experienced helper.
3. I will perform my initial turn after takeoff away from
the pit or spectator areas, and I will not thereafter fly
over pit or spectator areas, unless beyond my control.
4. I will operate my model using only radio control
frequencies currently allowed by the Federal
Communications Commission...
❏
1. Fuelproof all areas exposed to fuel or exhaust
residue such as the engine baffle in the cowl,
cowl mounting blocks, the wing saddle area, etc.
❏
2. Check the C.G. according to the measurements
provided in the manual.
❏
3. Be certain the battery and receiver are securely
mounted in the fuse. Simply stuffing them into
place with foam rubber is not sufficient.
❏
4. Extend the receiver antenna and make sure it
has a strain relief inside the fuselage to keep
tension off the solder joint inside the receiver.
❏
5. Balance the model laterally as explained in
the instructions.
❏
6. Use threadlocking compound to secure
critical fasteners such as the set screws that
hold the wheel axles to the struts, screws that
hold the carburetor arm (if applicable), screw-
lock pushrod connectors, etc.
❏
7. Add a drop of oil to the axles so the wheels
will turn freely.
❏
8. Make sure all of the hinges are securely glued
in place.
❏
9. Reinforce holes for wood screws with thin CA
where appropriate (servo mounting screws,
cowl mounting screws, etc.).
❏
10. Confirm that all controls operate in the correct
direction and the throws are set up according
to the manual.
❏
11. Make sure there are silicone retainers on all
the clevises and that all servo arms are
secured to the servos with the screws
included with your radio.
❏
12. Secure connections between servo wires and
Y-connectors or servo extensions, and the
connection between the battery pack and the
on/off switch with tape, heat shrink tubing or
special clips suitable for that purpose.
❏
13. Make sure servo extension cords do not
interfere with other systems (servo arms,
pushrods, etc.).
❏
14. Secure the pressure tap (if used) to the
muffler with high temp RTV silicone, thread
locking compound or J.B. Weld.
❏
15. Make sure the fuel lines are connected and
are not kinked.
❏
16. Use an incidence meter to check the wing for
twists and attempt to correct before flying.
❏
17. Balance the propeller (and spare propellers).
❏
18. Tighten the propeller nut and spinner.
❏
19. Place your name, address, AMA number and
telephone number on or inside the model.
❏
20. Cycle the receiver battery pack (if necessary)
and make sure it is fully charged.
❏
21. If you wish to photograph your model, do so
before the first flight.
❏
22. Range check the radio when you get to the
flying field.
FLYING
The Sea Fury is a great-flying model that flies
smoothly and predictably. The Sea Fury does not,
however, possess the self-recovery characteristics
of a primary R/C trainer and should be flown only by
experienced R/C pilots.
Fuel Mixture Adjustment
A fully cowled engine may run at a higher
temperature than an un-cowled engine. For this
reason, the fuel mixture should be richened so the
engine runs at about 200 rpm below peak speed. By
running the engine slightly rich, you will help prevent
dead-stick landings caused by overheating.
CAUTION (THIS APPLIES TO ALL R/C
AIRPLANES): If, while flying, you notice any unusual
sounds, such as a low-pitched “buzz,” this may
indicate control surface
flutter. Because flutter can
quickly destroy components of your airplane, any
time you detect flutter you must immediately cut the
throttle and land the airplane! Check all servo
grommets for deterioration (this may indicate which
surface fluttered), and make sure all pushrod
linkages are secure and free of play. If the control
surface fluttered once, it probably will flutter again
under similar circumstances unless you can
eliminate the free-play or flexing in the linkages. Here
are some things which can cause flutter: Excessive
hinge gap; Not mounting control horns solidly; Poor
fit of clevis pin in horn; Side-play of pushrod in guide
tube caused by tight bends; Poor fit of Z-bend in
servo arm; Insufficient glue used when gluing in the
elevator joiner wire; Excessive
play or backlash in
servo gears; and Insecure servo mounting.

During the last few moments of preparation your
mind may be elsewhere anticipating the
excitement of the first flight. Because of this, you
may be more likely to overlook certain checks
and procedures that should be performed before
the model is flown. To help avoid this, a checklist
is provided to make sure these important areas
are not overlooked. Many are covered in the
instruction manual, so where appropriate, refer to
the manual for complete instructions. Be sure to
check the items off as they are completed (that’s
why it’s called a
check list!).
