2. I will not fly my model aircraft higher than approximately

400 feet within 3 miles of an airport without notifying the
airport operator. I will give right of way to and avoid flying in
the proximity of full-scale aircraft. Where necessary an
observer shall be used to supervise flying to avoid having

models fly in the proximity of full-scale aircraft.

3. Where established, I will abide by the safely rules for the

flying site I use and I will not willfully and deliberately fly my

models in a careless, reckless and/or dangerous manner.

7. I will not fly my model unless it is identified with my
name and address orAMA number, on or in the model.

9. I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile or any kind).

Radio Control

1. I will have completed a successful radio equipment

ground 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.

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
or 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 slop-free. If it fluttered once, it will probably

flutter again under similar circumstances unless you can
eliminate the slop or flexing in the linkages. Here are
some things which can result in flutter: Excessive hinge
gap; Not mounting control horns solidly; Sloppy fit of
clevis pin in horn; elasticity present in flexible plastic
pushrods; Side-play of pushrod in guide tube caused by
tight bends; Sloppy fit of control rods in servo horns;

Insufficient glue used when gluing in torque rods;
Excessive flexing of aileron, caused by using too soft

balsa; Excessive "play" or "backlash" in servo gears; and
insecure servo mounting.

The Great Planes F-4 Phantom is a great-flying sport

model that flies smoothly and predictably. The F-4 does
not, however, possess the self-recovery characteristics of

a primary R/C trainer and should only be flown by
experienced RC Pilots.

Takeoff on "high" rates if you have dual rates on your
transmitter - especially if you are taking off into a
crosswind. For all models it is good practice to gain as

much speed as the length of the runway will permit before
lifting off. This will give you a safety margin in case the

engine quits. When the plane has gained enough flying
speed to safely lift off, gradually and smoothly apply up
elevator and allow the model to climb at a shallow angle
(do not yank the model off the ground into a steep climb!).

We recommend that you take it easy with your F-4

Phantom for the first several flights, gradually "getting

acquainted" with this great model as your engine gets fully
broken in. If you feel as though you have your hands full,
keep this in mind: pull back on the throttle stick to slow the

model down. This will make everything happen a little

slower and allow yourself time to think and react. Add and
practice one maneuver at a time, learning how the
F-4 behaves in each. For smooth flying and normal
maneuvers, use the low rate settings as listed on page 46.

Before it's time to land, you should climb your F-4 Phantom

to a safe altitude, reduce the throttle to an idle and check
out the model's low speed characteristics. Do this a few
times so you know what to expect upon landing and how
the Phantom handles stalls.

When it's time to land, fly a normal landing pattern and
approach. Keep a few clicks of power on until you are over
the runway threshold. For your first few landings, plan to
land slightly faster than stall speed.

Have a ball! But always remember to think about your
next move and plan each maneuver before you do it.
Impulsively "jamming the sticks" without any thought is

what gets most fliers in trouble rather than lack of flying
skill. Happy Landings!
