MAIN GEAR & WHEEL INSTALLATION

BALANCING THE MODEL

Using a scissors, cut the backing along the

bubble, removing a strip of backing about 1"

wide.

Carefully position the decal on the model

and, working from the center, rub the decal

down while peeling back the remainder of the

backing.

Note: Do not remove the decal backing from the

dashboard. Glue the decal with the backing

on to the dashboard. You can also place a

white backing on the dashboard before you

peel and apply the decal.

Collect the following items:

(2) Landing gear wire

(8) #2 x 5/16"screw

(4) Landing gear strap

(3) 2-1/2" wheel

(3) 5/32 wheel collar

(3) 6-32 x 1/8" Allen head set screw

(3) 5/32 eyelet

(1) .050 Allen wrench

Install the wheels on the axles, as shown.

The eyelet goes on first, followed by the

wheel, the wheel collar, and the set screw.

Glue the eyelet in place with a drop of ZAP

CA™.

At this time, also install the nosegear wheel.

Locate the landing gear slots in the bottom of

the wing and remove the covering material.

NOTE: If you desire the taildragger configuration,

go the the Landing Gear Installation in the

Taildragger Option section.

Insert the shorter end of the gear into the

hole in the bottom of the slot, so that it points

toward the center of the wing.

Use two nylon straps and four screws on

each side to secure the wire gear.

IMPORTANT: NEVER NEGLECT THIS STEP WITH

ANY AIRPLANE. If you try to fly a plane with the

balance point behind the recommended range, you

run the risk of having an unstable aircraft and the

strong likelihood of a crash. TAKE THE TIME TO

PROPERLY BALANCE YOUR MODEL!

To determine the Center of Gravity, measure back

on the fuselage 3-7/8" from the leading edge of

the wing. The C.G. range for this aircraft is 3-3/4

to 4-3/4".

Place the fully assembled aircraft on a model bal-

ancing stand, as shown above. You can make this

simple set-up with a couple of ¼" dowels with round-

ed tops, spaced 5" apart. Alternatively, lift the model

under the wing near the fuse by your finger tips. (You

may wish to get help from a friend if using the latter

method.)

Referring to the recommended balance

range for your model, move the position of the plane on

the balance stand until the model is level or the nose

slightly down.

If the is tail heavy, shift the R/C equip-

ment away from the heavy end of the model and

recheck until the model will balance within the

acceptable range. If shifting the R/C gear still does-

n't balance the model, add weight to the far end of

the nose or tail, respectively, until the model is cor-

rectly balanced. The least weight is needed when

added as far back or forward as possible. Fasten

the weight permanently in place.
