Glue the two plastic sleeves in the holes in the underside of the wing to act as load-
spreaders for the wing retaining screws.
Assembling the YAK 11 RENO
We recommend that you permanently connect 180 mm extension leads to the
receiver sockets for the aileron, landing flap and retract servos, as this makes it much
easier to connect the servos when rigging the aeroplane.
Connect the aileron, landing flap and retract servos to the extension leads. Connect
the compressed air hoses. Locate the locating dowels in the leading edge of the
wing, and insert them in the holes in the fuselage former; fit the two plastic screws to
attach the wing to the fuselage. Don’t over-tighten the retaining screws: tighten them
just to the point where the wings are securely held, and cannot shift.
Balancing the YAK 11 RENO
The completely equipped model, with the fueltank empty, should balance level at a
point about 170 mm aft of the wing root leading edge, ideally with the nose inclined
slightly down. It is easier to balance this aircraft when it is held inverted. If necessary,
adjust the position of the receiver battery until the model balances at the stated point;
alternatively glue lead ballast at nose or tail as required. Before flying the aircraft, set
the transmitter trims to centre, and ensure that all the control surfaces are also
exactly at centre (neutral).
