Throttle Hookup
All the materials to assemble a flexible-cable throttle pushrod as shown below are supplied in the kit. It should be
supported at the servo end so that it is aimed directly at the output arm on the throttle servo. Cut a support block from
scrap balsa and glue it firmly in place against the fuselage side. Epoxy the nylon outer tubing to the support block. Route
the cable so that it makes as few curves as possible and provide at least one support between the servo and the firewall to
keep it from buckling or flexing under load.
Aileron Hookup
The Spacewalker has been designed to use two aileron servos, one in each outer wing panel. Use servo extension wires
with a "Y" harness at the center section to connect the servos to the receiver. Radio manufacturers generally have these
items available as stock equipment or will make them on order. It is best to keep the extensions as short as possible since
excessively long wires have been known to cause interference under certain conditions.
Installation of the aileron servos and aileron pushrods is clearly shown on the plans (Plates 3 and 4). You will have to cut a
clearance notch in the wing's bottom rear spar to make room for the pushrod to travel (hence the reason for the spruce
spar doubler at that location). Adjust the 4-40 clevises until both ailerons are lined-up with the rest of the wing. Notice in
the photo that a short length of fuel tubing has been forced over the clevis to positively hold the clevis closed. This simple
safety feature should be used on all of the clevises used in your model.
Receiver and Battery
Wrap the receiver and battery pack separately in foam rubber (such as
SIGRF240), held on with rubber bands or tape, to protect them from engine
vibration. The best location in the fuselage for the receiver and battery can't be
determined until your model is completely finished. Shifting these components
fore or aft can help get the model balanced properly. Be certain that both are
secured into position so that they can't shift around in flight.
The receiver antenna can be run out of the bottom of the fuselage and taped at the aft end. This will expose the antenna
without making it too conspicuous. It may also be mounted inside the fuselage in a long piece of nylon tubing glued into
one of the corners. The switch and charging jack can be mounted on PT-2 in the cockpit opening for easy access.
WARNING - DANGER! -Important: Read These Warnings:
Do Not fly control line or towline models within 300 feet of electric power lines. Instant death from
electrocution can result from coming near them. Direct contact is not necessary.
A model airplane motor gets very hot and can cause serious burns. Do not touch the motor during or after
operation.
Keep clear of the propeller. It can cut off a finger or put out an eye. Make sure the propeller is securely
fastened in place and is not cracked.
Model airplane fuel is flammable and poisonous. Take the same precautions while transporting and using it
that you would with a can of gasoline or a bottle of poison.
Remember that it is possible to lose control of a model airplane. Do not fly in locations where the model
may hit people or damage property if loss of control occurs.
Check your model and equipment regularly to insure it is in safe operating condition.
