Align the elevator horn on the inside
edge of the elevator and mount using
the two #2x1” screws and nylon
plate.
Locate the two 2mm pushrods with
clevis and install the silicone keeper
on clevis. Hook clevis to horn and
mark where it meets the servo arm.
Make a 90 degree bend and cut at
3/8”. You will need to drill out the
servo arm with your 5/64” drill and
install the rod using the nylon snap-
r-keeper to retain it. Do this to both
rudder and elevator.
Cut the covering from the throttle
servo cutout just behind engine
mount. The opening is made for a Mini
servo. If you use a standard servo you
will need to cut the opening larger.
Trial fit your engine. The right thrust
is built in. Position the engine so you
have about 1/4” clearance from the
front of the prop hub to the front of
the fuselage. Mark the hole loca-
tions and drill a 1/8” hole for the
3mmx20mm bolts. Mount engine using
the eight 3mm washer and four air-
craft lock nuts.
Locate the fuel tank and position it
on the left side of the fuselage. Mark
the location of the holes for the tie
wraps at the top and bottom of tank
aligned with the groves in the tank.
Pay attention to the lightning holes
in the front of the fuselage under
the covering and make sure you are
not over one of them. Drill a 3/16”
hole at the four locations marked.
Two pieces of balsa are supplied to
space the tank out from the fuselage.
