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 fuse. 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 thread locking 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
flying field.
The Revolver .61 ARF is a great-fl ying model that fl ies
smoothly and predictably. The Revolver 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.
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.
