INSTALLING THE CANOPY HATCH.

1) It is critical that your airplane be bal-

anced correctly. Improper balance will cause

your plane to lose control and crash. The cen-

ter of gravity is locate

10-13cm back from the

leading edge of the wing, measured at center

rib of upper wing (see picture below).

BALANCING.

When balanced correctly, the airplane should

sit level or slightly nose down when you lift it

up with your fingers.

CG=10-13cm.

2) Turn on the radio system, and with the

trim tabs on the transmitter in neutral, center

the control surfaces by making adjustments

to the clevises or adjustable servo connectors.

The servo arms should be centered also.

1) We highly recommend setting up the

ULTIMATE using the control throws listed at

right. We have listed control throws for both

Low Rate (initial test flying/sport flying) and

High Rate (aerobatic flying).

CONTROL THROWS.

2) If the nose of the plane falls, the plane

is nose heavy. To correct this first move the

battery pack further back in the fuselage. If

this is not possible or does not correct it, stick

small amounts of lead weight on the fuselage

sides under the horizontal stabilizer. If the tail

of the plane falls, the plane is tail heavy. To

correct this, move the battery and receiver for-

ward orif this is not possible, stick weight onto

the firewall.

 3) When the elevator, rudder and aileron

control surfaces are centered, use a ruler and

check the amount of the control throw in each

surface. The control throws should be

measured at the widest point of each sur-

face!

 4) By moving the position of the adjust-

able control horn out from the control surface,

you will decrease the amount of throw of that

control surface. Moving the adjustable con-

trol horn toward the control surface will in-

crease the amount of throw.

INITIAL FLYING/SPORT FLYING

Do not use the aerobatic settings for

initial test flying or sport flying.

Ailerons: 3/16” up 3/16” down

Elevator: 3/8” up 3/8” down

Rudder: 3/4” right and left

AEROBATIC FLYING

Ailerons: 3/8” up 3/8” down

Elevator: 7/8” up 7/8” down

Rudder: 1 1/4” right and left
