length (be careful not to glue the two strings together) and

the spoilers should open and close together. Adjustments

can be made at the toothpick end if needed.

RADIO SETTINGS

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 CG 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 ARF'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.
