When installing the propeller adapter in the next procedure, we strongly suggest applying threadlocker
to the grub screw to prevent the grub screw from loosening during flight.
❑
Slide the propeller adapter onto the motor shaft and tighten the grub screw firmly, using a hex wrench.
☞
Make sure that the propeller adapter does not rub against the motor.
❑
Slide the propeller onto the propeller adapter
(making
sure that the molded numbers on the front of the propeller
are toward the front of the wing)
and secure it into place,
using the flat washer and hex nut provided. Make sure to
tighten the nut firmly to keep the propeller from coming loose
during flight.

Because the motor is mounted and wired
in a pusher configuration, the propeller must be installed
backwards. Verify that you install the propeller with the
molded numbers toward the front of the wing.

It is critical that your airplane be balanced correctly. Improper balance will cause your airplane to lose
control and crash!
Center of Gravity Location:
6-1/8" back from the leading edge of the wing, measured at the centerline of the wing.

WARNING

✦
✦
✦
✦
This is the recommended C/G location. Because there is little margin of error when locating the C/G of
a flying wing, we suggest not attempting to move the C/G forward or aft from its initial location. Doing so can result in
very erratic flight characteristics.
☞
Balance the Hyper Wing 400 EP with the flight battery
installed.
❑
Measure and draw two marks on the bottom of the wing, 6-1/8" back from the leading edge, measured at the
centerline of the wing.
❑
Place your fingers on the marks, and carefully lift the airplane. If the nose of the airplane falls, the airplane is nose
heavy. To correct this, move the flight battery back far enough to bring the airplane into balance. If the tail of the airplane
falls, the airplane is tail heavy. To correct this, move the flight battery far enough forward to bring the airplane into balance.
When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers at the C/G
location. It should not set with the tail down.
DO NOT FLY THE AIRPLANE OUTSIDE OF THE RECOMMENDED BALANCE POINT OR AN
UNCONTROLLABLE CRASH COULD RESULT!
