Decal Application

To facilitate positioning and eliminate air bubbles, apply the

decals wet.

❏

1. Peel the decal from the sheet and spray the sticky side

with window cleaner.

❏

2. Position the decal and squeegee out air bubbles

and window cleaner with a piece of soft balsa or similar.

Balance the Model

Balanced anywhere within the recommended C.G. range

the Kunai ﬂ ies well. Balanced toward the aft end of the C.G.

range the Kunai will respond faster and glide slower for

maximizing lift in rising air as well as reduced ground speed

for feather-like landings, but will also require more pilot input

in windier conditions. Balanced nearer the forward end of the

C.G. range the Kunai will be more stable for faster speeds

and better wind penetration.

❏

1. If you haven't yet done so, mount the propeller shaft to

the motor using a drop of threadlocker on the set screws and

a quality, 1.5mm hex driver to tighten the screws—be certain

the back of the propeller shaft does not contact the heads of

the motor mounting screws.

❏

2. Mount the back plate/propeller hub assembly to

the propeller shaft and tighten the nut. Then, mount the

spinner cone.

Recommended

Starting C.G.

+/- 1/2" [ 13 mm]

❏

3. The recommended beginning C.G. location is 2-3/4"

[70m] back from the leading edge of the wing where it meets

the fuselage. The forward and aft C.G. are 1/2" [13mm] either

side of that. Measure and mark the C.G. on the bottom of the

wing according to the measurements—narrow strips of tape

allow you to feel the lines with your ﬁ ngers when suspending

the plane while balancing.

❏

4. Mount the wing to the fuselage. The Kunai must be

in ready-to-ﬂ y condition with the battery installed and the

propeller mounted.

C.G. Range

2-3/4" [ 70 mm]
