2) I will not fl y my model aircraft in the presence of spectators
until I become a qualifi ed fl ier, unless assisted by an
experienced helper.
3) At all fl ying sites a straight or curved line(s) must be
established in front of which all fl ying takes place with the
other side for spectators. Only personnel involved with
fl ying the aircraft are allowed at or in the front of the fl ight
line. Intentional fl ying behind the fl ight line is prohibited.
4) I will operate my model using only radio control
frequencies currently allowed by the Federal Com-
munications Commission.
5) I will not knowingly operate my model within three
miles of any pre-existing fl
ying site except in
accordance with the frequency sharing agreement
listed [in the complete AMA Safety Code].
9) Under no circumstances may a pilot or other person touch
a powered model in fl ight; nor should any part of the
model other than the landing gear, intentionally touch
the ground, except while landing.
CHECK LIST
During the last few moments of preparation your mind
may be elsewhere anticipating the excitement of the fi rst
fl ight. Because of this, you may be more likely to overlook
certain checks and procedures that should be performed
before the model is fl own. To help avoid this, a check list
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!).
❏
1. Check the C.G. according to the measurements
provided in the manual.
❏
2. Be certain the receiver is securely mounted in the
fuse. Simply stuffi ng it into place with foam rubber is
not suffi cient.
❏
3. Extend your receiver antenna.
❏
4. Balance your model laterally as explained in
the instructions.
❏
5.
Use threadlocking compound to secure critical
fasteners such as set screws, nuts, etc.
❏
6. Add a drop of oil to the axles so the wheels will
turn freely.
❏
7. Make sure all hinges are securely glued in place.
❏
8. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, control horn
screws, etc.).
❏
9. Confi rm that all controls operate in the correct direction
and the throws are set up according to the manual.
❏
10. 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.
❏
11.
Secure connections between servo wires and
Y-connectors or servo extensions with vinyl tape, heat
shrink tubing or special clips suitable for that purpose.
❏
12. Make sure any servo extension cords you may have
used do not interfere with other systems (servo arms,
pushrods, etc.).
❏
13. Balance your propeller (and spare propellers).
❏
14. Tighten the propeller nut and spinner.
❏
15.
Place your name, address, AMA number and
telephone number on or inside your model.
❏
16. If you wish to photograph your model, do so before
your fi rst fl ight.
❏
17. Range check your radio when you get to the
flying field.
FLYING
The Sequence ARF is a great-fl ying model that fl ies smoothly
and predictably. The Sequence does not, however, possess
the self-recovery characteristics of a primary R/C trainer and
should be fl own only by experienced R/C pilots.
CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If,
while fl ying, you notice an alarming or unusual sound such
as a low-pitched “buzz,” this may indicate control surface
fl utter. Flutter occurs when a control surface (such as an
aileron or elevator) or a fl ying surface (such as a wing or
stab) rapidly vibrates up and down (thus causing the noise).
In extreme cases, if not detected immediately, fl utter can
actually cause the control surface to detach or the fl ying
surface to fail, thus causing loss of control followed by
an impending crash. The best thing to do when fl utter is
detected is to slow the model immediately by reducing
power, then land as soon as safely possible. Identify
which surface fl uttered (so the problem may be resolved)
by checking all the servo grommets for deterioration or
signs of vibration. Make certain all pushrod linkages are
secure and free of play. If it fl uttered once, under similar
circumstances it will probably fl utter again unless the
problem is fi xed. Some things which can cause fl utter are;
Excessive hinge gap; Not mounting control horns solidly;
Poor fi t of clevis pin in horn; Side-play of wire pushrods
caused by large bends; Excessive free play in servo
gears; Insecure servo mounting; and one of the most
prevalent causes of fl utter; Flying an over-powered model
at excessive speeds.
Takeoff
Before you get ready to takeoff, see how the model handles
on the ground by doing a few practice runs at low speeds on
the runway. Hold “up” elevator to keep the tail wheel on the
ground. If necessary, adjust the tail wheel so the model will
roll straight down the runway. If you need to calm your nerves
before the maiden fl ight, shut the motor down and bring the
