Radio Control
1) I will have completed a successful radio equipment ground
check before the fi rst fl ight of a new or repaired model.
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 Communications 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.
❏
1. Check the C.G. according to the measurements
provided in the manual.
❏
2. Be certain the battery and receiver are securely
mounted in the fuselage. Simply stuffi ng them 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 the set screws that hold the wheel
axles to the struts, screws that hold the carburetor arm
(if applicable), screw-lock pushrod connectors, 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, cowl mounting
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, and the connection
between your battery pack and the on/off switch 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. Secure the pressure tap (if used) to the muffl er with
high temp RTV silicone, threadlocking compound or
J.B. Weld.
❏
14. Make sure the fuel lines are connected and are
not kinked.
❏
15. Balance your propeller (and spare propellers).
❏
16. Tighten the propeller nut and spinner.
❏
17. Place your name, address, AMA number and telephone
number on or inside your model.
❏
18. Cycle your receiver battery pack (if necessary) and
make sure it is fully charged.
❏
19. If you wish to photograph your model, do so before
your fi rst fl ight.
❏
20. Range check your radio when you get to the fl ying fi eld.
The Cherokee .40 ARF is a great-fl ying model that fl ies
smoothly and predictably. The Cherokee .40 ARF 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.

Fuel Mixture Adjustments

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.
If you have dual rates on your transmitter, set the switches
to "high rate" for takeoff, especially when taking off in
a crosswind. Although this model has good low-speed
characteristics, you should always build up as much speed
as your runway will permit before lifting off, as this will give
you a safety margin in case of a "fl ame-out." When you fi rst
