Mount the Propeller
❏
1. Slide the collet type prop adapter onto the motor shaft.
❏
2. Install the spinner backplate on the prop adapter, followed
by the propeller, prop washer and prop nut. Caution: The
propeller blades are sharp. Do not slide your hand along the
edge of the propeller.
❏
3. Position the propeller in the slot in the front of the spinner
backplate and tighten the prop nut. Use a small crescent
wrench to tighten the prop nut securely. Sometimes, as the
prop nut is tightened, the prop adapter turns with it causing
the nut not to tighten. But, if the nut is turned quickly, it should
tighten after another turn or two.
❏
4. Attach the spinner cone to the backplate with the two
2.5x8mm self-tapping screws.
Check the C.G. (Center of Gravity)
The C.G. (Center of Gravity) is the location on the wing
where the model balances and has a great effect on how
the plane will fl y. If the C.G. is too far aft (tail heavy), the
model will be too responsive. If the C.G. is too far forward
(nose heavy), the model will not be responsive enough. As
provided to you, your Sensei should already be properly
balanced, or very nearly properly balanced, but it’s a good
idea to check the balance just in case. Follow the instructions
to make sure the model is balanced properly and the C.G.
is in the correct location.
❏
1. Install the motor battery, but do not connect it to the
ESC. Also install the battery hatch. All the rest of the parts of
the plane should already be installed, including the propeller
and spinner.

2. Two plastic aileron servo covers can be found on the
bottom of the wing. Draw a mark 1/4" [7mm] back and 1/4"
[7mm] forward from the front of the aileron servo cover. The
plane should balance between the two marks. Place your
fi ngers between the marks and lift the plane. The fuselage
should remain level – it may be helpful to have an assistant
view the plane from the side. If the fuselage does not rest
level, try moving your fi ngers under the wing. Your fi ngers
can be moved between the marks. As long as the fuselage is
level with your fi ngers between the marks, the balance range
is acceptable, and the plane is ready to fl y. However, if after
moving your fi ngers forward past the front mark, the nose
