Use the sketch to make sure the control surfaces are moving the

correct directions.

The control throws are as follows:

Elevator

1/2" [13mm] up

1/2" [13mm] down

Rudder

1-1/2" [38mm] left

1-1/2" [38mm] right

Spoilers

90º to the upper surface of the wing

BALANCE THE MODEL

Note: This section is VERY important and must not be

omitted! A model that is not properly balanced will be unstable and

possibly unflyable.

Accurately mark the balance point on the bottom of the wing on

both sides of the fuselage. The balance point is located 3-1/4"

[83mm] back from the leading edge. This is the balance point at

which your model should balance for your first flights. Later, you

may wish to experiment by shifting the balance up to 5/16" [8mm]

forward or back to change the flying characteristics. Moving the C.G.

forward of the spar will add some stability but it will decrease the

overall performance of the sailplane. Moving the balance behind

the spar makes the model more agile with a lighter and snappier

"feel" and improves the sailplane's response to air currents. In any

case, please start at the location we recommend and do not at any

time balance your model outside the recommended range.

With the wing attached to the fuselage, and all parts of the model

installed (ready to fly), lift the model by picking it up with a finger on

each bottom inner spar. If the tail drops when you lift, the model is

"tail heavy" and you must add weight to the nose to balance. If the

nose drops, it is "nose heavy" and you must add weight to the tail

to balance. The model should hang with a slight nose down

attitude. Add BB's or lead to the weight compartment at the front of

the fuselage to correct a tail heavy model. In the unusual

circumstance that you would have a nose heavy model, you can

switch the receiver and battery or even move the receiver behind

the servos. Getting the weight farther back helps correct the "nose

heaviness."

CHECKING FOR WARPS

This is a very important step and should be done occasionally

throughout the flying season. A sailplane's wing is most efficient

when it is not twisted or warped at all. "Washout" (wing trailing

edges twisted up at the tip) helps make a poor wing design fly

better by adding some stability (preventing stalls) at slow speeds

but it cuts down on the wing efficiency at normal speeds. The Spirit

Select's wing is designed to fly well at slow speeds without any

washout, and therefore we recommend you check to make sure

the wings are "flat" using the following procedure:

Set the wing so an inner panel is resting on a flat surface. Any warp

(twist) will show up by causing a corner of the panel to rise off the

work surface.

To remove the warp, gently twist the wing in the opposite direction

while a helper glides an iron or heat gun over the covering on both

the top and the bottom of the panel to re-shrink the covering. Hold

the twist until the covering cools and then recheck for warps. It may

take several tries to get a warp out but it is worth it as you will end

up with a sailplane that flies straight and true and responds to air

currents like a high performance sailplane should.

Follow the same procedure to check all four wing panels and then

go back and double check them. Sometimes you put a warp in one

panel while trying to fix another. You should also look at the tail

surfaces as they too can warp.

PREFLIGHT

Charge the Batteries

Follow the battery charging procedures in your radio instruction

manual. You should charge your transmitter and receiver batteries

the night before you go flying, and at other times as recommended

by the radio manufacturer.

Find a Safe Place to Fly

The best place to fly your R/C model is an AMA (Academy of Model

Aeronautics) chartered club field. Ask your hobby shop dealer if

there is such a club in your area and join. Club fields are set up for

R/C flying which makes your outing safer and more enjoyable. The

AMA can also tell you the name of a club in your area. We

recommend that you join AMA and a local club so you can have a

safe place to fly and also have insurance to cover you in case of a

flying accident. (The AMA address is listed on page 2 of this

instruction book).

If a club and its flying site are not available, you need to find a

large, grassy area at least 6 miles away from any other R/C radio
