16. Connect the aileron horn to the servo arm with the
hardware shown in the illustration—the stand-off on the
aileron horn is optional and not used with the servos shown,
but if your servo spacing is different the standoffs may be
used to keep the pushrod perpendicular to the aileron horn.
Be sure to use threadlocker on the nuts.

ASSEMBLE THE FUSELAGE

CAUTION: The turtledeck and fuselage bottom of the
Sequence 1.20 are made from balsa-covered foam.
Some solvents and adhesives will attack the foam, so use
care—especially when using CA which will defi nitely "eat"
into the foam.

Mount the Landing Gear

❏
1. If you haven't yet done so, use a covering iron with a
cover sock to go over the fuselage to remove any wrinkles
and bond the covering to the airframe—remember to support
the inside of the sheeting where possible.
❏
2. Test-fi t the main landing gear legs in the fuselage to
distinguish the left from the right and mark them as such.
❏
3. Mount 5/32" [4mm] axles to the main landing gear with
the large lock nuts and threadlocker. Use a rotary tool with a
fi ber-reinforced cutoff wheel to accurately cut the axles to a
length of 1" [25mm], as shown in the illustration. Grind or fi le
a fl at spot on the end of both axles.
