suitable for the flaps and ailerons. The elevator and rudder
should each be operated by a servo with approximately 70
oz-in torque. The throttle and nose wheel may be operated
by standard servos.

The following servo extensions and Y-harnesses were
also used to build the Giant Big Stik ARF as shown in
the manual.

❏

(2) 36" [910mm] servo extensions for elevator and
rudder (HCAM2726 for Futaba)

❏

(2) 24" [610mm] servo extensions for ailerons
(HCAM2721 for Futaba)

❏

(2) 6" [150mm] servo extensions for flaps (HCAM2701
for Futaba)

❏

(2) Futaba AEC-13 Y-connectors for flap and aileron
servos (FUTM4130)

A battery pack with a minimum of 1,000mAh should also
be used. When flying giant-scale models such as this,
ALWAYS check the battery condition before each flight.

In addition to the items listed in the

“Decisions You Must

Make” section, following is the list of hardware and
accessories required to finish the Giant Big Stik ARF. Order
