Sokol Assembly Guide
Make a mount for the elevator servo by sanding a curve in the bottom of a scrap piece
of 1/8” (3mm) balsa. Epoxy this in position at the rear of the wing opening.
Epoxy the elevator servo in position.
Clamp the elevator in neutral position, bend an L or Z shape in the wire push rod, to
align with the servo arm. If using an L bend use plastic keeper or a small tube to hold
the wire in position. If using a Z bend fitting can be facilitated by drilling a hole in the
fuselage side to unscrew the servo horn retaining screw.
Secure the front of the Bowden Cable (push rod outer) by gluing it to another piece of
scrap balsa epoxied to the side of the fuselage.
Drill the mounting holes for the electric motor, and fit the motor and speed control.
It is probably best to fit the receiver on top of, or behind the elevator servo. Tape the
two 2.4GHz antennas to the fuselage sides, one vertical and one horizontal, on the
fuselage underside.
Glue some Velcro (hook & loop) tape to the underside of the fuselage to allow the the
battery to be safely secured in position, do it does not move during flight. Before flying
mark the battery position to achieve the correct centre of gravity.
