SECTION 17: BALANCING THE SE5a SCOUT ARF

Ruler
IMPORTANT It is critical that your airplane be balanced correctly. Improper balance will cause your airplane to lose
control and crash!
Center of Gravity Location:
2-3/8" to 2-3/4" back from the leading edge of the TOP wing, measured at the wing centerline.
WARNING This is the recommended C/G range. For test-flying we suggest you start with the C/G in the middle of
the range (2-9/16"), then move it farther back as you become familiar with the flying characteristics of the airplane.
It is not recommended that the C/G be located any farther back than 2-3/4".
Balance the SE5a Scout ARF with the fuel tank empty.
Install both wings onto the fuselage. Make sure to install the outer struts, too. Apply two short pieces of masking tape
onto the bottom of the TOP wing, 2-9/16" back from the leading edge, measured at the wing centerline.
Place your fingers on the masking tape, and carefully lift the airplane. If the nose of the airplane falls, the airplane is
nose heavy. To correct this, move the battery pack and/or receiver 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 battery pack and/or receiver forward far
enough 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.
Once you have flown and become familiar with the flight characteristics of the airplane, the C/G can be moved fore or
aft within the C/G range to change the flight performance. Moving the C/G back will cause the airplane to be more
responsive, but less stable. Moving the C/G forward will cause the airplane to be more stable, but less responsive.
DO NOT FLY THE AIRPLANE BEYOND THE RECOMMENDED BALANCE RANGE OR AN

SECTION 18: CONTROL THROWS

We recommend setting up the SE5a Scout ARF using the control throws listed below. These control throws are suggested
for initial test-flying because they will allow the airplane to fly smoother and make it easier to control.
Ailerons:
Elevator:
Rudder:
IMPORTANT The control throws are measured from the widest point of the control surfaces.
VERY IMPORTANT
cutting 1/4" lengths of the clear tubing provided and sliding one piece over each clevis. The tubing will prevent the
clevises from popping open during flight.
YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:
UNCONTROLLABLE CRASH COULD RESULT!

1/2" Right 1/2" Left
After you are finished adjusting the pushrods and the control throws, we strongly suggest
