balance point is 2-1/4 to 2-1/2” back from the

leading edge of the wing next to the fuselage. It is always better to

fly slightly nose heavy, then slowly move the balance point back till

the plane flies the way you like it.

Control Throws

Aileron 1/4” to 3/8”

Elevator 3/8” to 1/2”

With everything installed, mount the wing and care-

fully check the Center of Gravity (CG). One way is to

perch the model on the thumb and forefinger of your

left hand (if you’re right handed), while steadying the

model with the other. A much better way is to use a

balancing set-up, which can be made with a couple

of 1/4” dowels with rounded tops, spaced just

enough apart to clear the fuse. Mark the desired CG

on the underside of the wing, and then set the model

on the dowels at that location. Add weight if neces-

sary for balance. The least weight is needed when

added as far forward or back as possible.

DO NOT attempt to fly the model with the CG

EVEN SLIGHTLY BEHIND the rear most recom-

mended position.

Before going to the field to fly, with batteries fully-

charged, turn on receiver and transmitter and actu-

ate all controls many times until you are satisfied

with all functions. Prior to the beginning of each

day’s flying, make a range check of your equipment

in accordance with the manufacturer’s instructions in

general, with antenna collapsed, you should have at

least 100 feet range on the ground. To check this,

set the model facing away from you, turn on both the

transmitter and receiver switches, and walk away

while transmitting signals. Watch to see that no sig-

nals are missed until you are at least 100 feet away.

Do not attempt any flights unless the equipment

works perfectly.Be careful not to use your transmitter

when someone else on the field is flying or testing on

the same frequency.

LEARNING TO FLY

Flying R/C is both fun and challenging. As with other

portions of this book, the following section is meant to

introduce you to the basics. Read carefully before tak-

ing your model out to the field and attempting first flights.

And remember, becoming an R/C pilot takes time and

patience, but the rewards are well worth the effort.
