3. Checking the rudder direction is different than the elevator
and ailerons. The WISE gyro corrects heading by detecting
sudden changes in yaw (the direction the nose is pointing). In
order to check this, hold the plane level with one hand near the
front of the plane and the other near the tail. Quickly pull the
tail toward you while keeping the plane level. Watch the rudder
while you do this. The rudder will briefl y move to the left as it
tries to compensate for the change in yaw that you caused.
If the WISE gyro operated as it was supposed to then skip on
to the next section.
If any of the three controls we checked
move opposite what they are supposed to,
STOP!
Please
contact Product Support.
Re-check steps 1-3 to confi rm the
WISE gyro is operating the controls in the correct directions.
Mount the Propeller
❏
1. Before installing the propeller, let’s make sure the fail
safe is working correctly. Turn on the transmitter and then
plug in the fl ight battery. Momentarily move the throttle stick
up and confi rm the motor spins. Okay, now bring the throttle
back to idle. With the fl ight battery still plugged in, turn off the
transmitter (normally we would NEVER turn off the transmitter
with the fl ight battery still connected but the motor has no
propeller installed so it is safe to do so). With the transmitter
OFF and the fl ight battery connected, the motor should be
still. If it started to rotate when you turned off the transmitter
then you need to reset the fail safe in the receiver. The throttle
position that the fail safe defaults to when it loses signal
from the transmitter is set when you bind the receiver to the
transmitter. Go back in the manual to the step about binding
the receiver and repeat it, being sure the throttle stick is in
the IDLE position when you press the LINK button.

2. Slide the collet type prop adapter onto the motor shaft.
❏
3. 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.
❏
4. 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.
❏
5. 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.
