❏
2. With the wings attached to the fuselage, all parts of the
model installed (ready to fl y) and the battery installed, lift the
model with two fi ngers at the lines you made.
❏
3. If the plane does not sit level with your fi ngers on the
lines, you can shift them forward or aft 1/8” [3mm]. If the tail
continues to drop even with your fi ngers 1/8” [3mm] aft of the
lines, the model is “tail heavy”. You will need to add weight to
the nose. If the nose continues to drop even with your fi ngers
all the way to the forward lines, the model is “nose heavy”.
You will need to move the receiver aft.
❏
4. If you found it necessary to add weight or move the
receiver, recheck the C.G. to confi rm the plane now balances
between the lines. Do not fl y a plane that has not been
properly balanced!
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. Stick-on lead weight can be
purchased from your hobby supplier (GPMQ4485). An
airplane that has been laterally balanced will track better
in loops and other maneuvers.
PREFLIGHT
Identify Your Model
No matter if you fly at an AMA sanctioned R/C club site
or if you fly 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 flying sites and AMA sanctioned flying events.
Fill out the identification tag on page 24 and place it on
or inside your model.
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 motor mounting screws and bolts loosen, possibly with
disastrous effect, but vibration may also damage your receiver
and battery.
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.
Range Check
The “range” is the safe operating distance from the transmitter
to the receiver, and should be as far as you can clearly see
the model. With the assistance of another person, place the
aircraft on the ground and walk 100 feet (30m) away from
the model. With the transmitter pointed directly at the model,
operate the transmitter’s controls, and ensure the movement
of all surfaces is according to the movement of the transmitter.
MOTOR SAFETY PRECAUTIONS
Failure to follow these safety precautions may result in
severe injury to yourself and others.
● Get help from an experienced pilot when learning
to operate motors.
● Use safety glasses when starting or running motors.
● Do not run the motor in an area of loose gravel or
sand; the propeller may throw such material in your
face or eyes.
● Keep your face and body as well as all spectators
away from the plane of rotation of the propeller as
you run the motor.
● Keep these items away from the prop: loose clothing,
shirt sleeves, ties, scarfs, long hair or loose objects
such as pencils or screwdrivers that may fall out of
shirt or jacket pockets into the prop.
