The canopy
The canopy should be attached to the fuselage using four 8 mm long countersunk
self-tapping screws. Place the canopy on the fuselage and position it with the front
edge flush with the black film. Drill holes for the four retaining screws and fit the
screws as shown in the picture.
The aerials can now be glued to the fuselage, the panoramic light on the fin tip, and
the tail light and aerial on the canopy as shown.
The final step is to apply the self-adhesive decals and name placards to the model.
We suggest that you position them as shown in the picture on the title page of these
instructions, and in the kit box illustrations.
Assembling the PIPER CHEROKEE
We recommend that you connect a 100 mm extension lead permanently to each of
the appropriate receiver sockets (2 and 5); this makes it easier to connect the aileron
servos to the receiver when you rig the model.
Connect the aileron servos to the extension leads already plugged into the receiver,
then insert the hardwood dowels into the holes in the fuselage former before fitting
the two plastic screws to secure the wing. Take care not to over-tighten them: they
should be tightened just to the point where the wings are firmly seated.
Balancing the PIPER CHEROKEE
Assemble the model completely (fueltank empty), hold it inverted and support it under
both wing roots at a point about 95 mm aft of the wing leading edge. The CG position
is correct when the model hangs level, with the nose inclined slightly down. If
necessary, re-position the receiver battery or glue lead ballast to the nose or tail to
obtain the correct balance. All the control surfaces must be exactly at centre when
the transmitter sticks and trims are in the neutral position; check this before flying the
model for the first time.
Control surface travels for normal flying
Ailerons
11 mm up, 11 mm down
Elevator
12 mm up, 12 mm down
Rudder
35 mm right, 35 mm left
We recommend that you set 30% exponential on all the flying controls at the
transmitter:
Important:
When fitting and adjusting the various linkages you should ensure that they move
freely, without binding, are able to move to their full extent - including trim travel - and
are not obstructed mechanically at any point.
When you move the rudder stick to the right, the rudder should also deflect to the
right (left stick: left rudder). Pull the elevator stick back towards you, and both
elevators must deflect up (stick forward: elevators down). If you move the aileron
stick to the right, the right aileron should rise, the left aileron fall. When you move the
throttle stick forward, the motor should run to the full-throttle position, i.e. the
carburettor barrel should be fully open. With the throttle stick and the trim fully back,
