residue may soften the adhesive and cause the weight to fall
off. Instead, permanently attach the weight with glue or screws.
❏
4. IMPORTANT: If you found it necessary to add any weight,
recheck the C.G. after the weight has been installed.

Balance the Model Laterally

❏
1. With the wing level, have an assistant help you lift the
model by the engine propeller shaft and the bottom of the
fuse under the TE of the fi n. Do this several times.
❏
2. If one wing always drops when you lift the model, it means
that side is heavy. Balance the airplane by adding weight to the
other wing tip. An airplane that has been laterally balanced
will track better in loops and other maneuvers.

PREFLIGHT

Identify Your Model

No matter if you fl y at an AMA sanctioned R/C club site or if
you fl y somewhere on your own, you should always have your
name, address, telephone number and AMA number on or
inside your model. It is required at all AMA R/C club fl ying sites
and AMA sanctioned fl ying events. Fill out the identifi cation
tag on page 35 and place it on or inside your model.

Charge the Batteries

Follow the battery charging instructions that came with your
radio control system to charge the batteries. You should always
charge your transmitter and receiver batteries the night before
you go fl ying, and at other times as recommended by the
radio manufacturer.
CAUTION: Unless the instructions that came with your
radio system state differently, the initial charge on new
transmitter and receiver batteries should be done for 15
hours using the slow-charger that came with the radio
system. This will "condition" the batteries so that the next
charge may be done using the fast-charger of your choice.
If the initial charge is done with a fast-charger the batteries
may not reach their full capacity and you may be fl ying with
batteries that are only partially charged.

Balance Propellers

Carefully balance your propeller and spare propellers before
you fl y. An unbalanced prop can be the single most signifi cant
cause of vibration that can damage your model. Not only
will engine mounting screws and bolts loosen, possibly with
disastrous effect, but vibration may also damage your radio
receiver and battery. Vibration can also cause your fuel to
foam, which will, in turn, cause your engine to run hot or quit.
We use a Top Flite Precision Magnetic Prop Balancer
(TOPQ5700) in the workshop and keep a Great Planes
Fingertip Prop Balancer (GPMQ5000) in our fl ight box.

Ground Check

If the engine is new, follow the engine manufacturer's
instructions to break-in the engine. After break-in, confi rm
that the engine idles reliably, transitions smoothly and rapidly
to full power and maintains full power—indefi nitely. After you
run the engine on the model, inspect the model closely to
make sure all screws remained tight, the hinges are secure,
the prop is secure and all pushrods and connectors are secure.

Range Check

Ground check the operational range of your radio before the
fi rst fl ight of the day. Refer to your radio manual for the range
checking procedure of your radio system. During the check,
have an assistant stand by your model and, while you work the
controls, tell you what the control surfaces are doing. Repeat
this test with the engine running at various speeds with an
assistant holding the model, using hand signals to show you
what is happening. If the control surfaces do not respond
correctly, do not fl y! Find and correct the problem fi rst. Look
for loose servo connections or broken wires, corroded wires
on old servo connectors, poor solder joints in your battery
pack or a defective cell.
