Section 18: Balancing Your Alpha RTF
Adding Weights to Correct the Balance
Due to manufacturing differences, it is possible that the
Alpha 40 RTF may not be balanced properly. Weights can
be added to either the tail or the nose of your Alpha RTF
if it does not balance properly. Stick-on weights available
at your local hobby store are the easiest to use, and come
in sizes that are easily placed on your plane. Add just
enough weight as necessary to balance your plane. Once
the weight has been added, make sure it is secure and will
not fall off in flight.

Section 19: Flight Preparations

Flight preparations must be checked each time you travel
to the flying field. Because the Alpha RTF will encounter
a variety of situations, it is best to keep an eye on the
various components of your model to keep it in the best
flying condition.

Checking the Frequency
When using a Spektrum radio system, follow the
guidelines for use of DSM radio systems at your
particular field.

Checking the Controls
Before starting your engine, check to make sure the
controls are operating in the correct directions and the
linkages and surfaces are not binding anywhere. Also look
at the clevises and clevis retainers to make sure they are
secure and will not come loose or fail in flight.


Fueling the Alpha RTF
Fill the fuel tank with the proper fuel. Fill the tank by
connecting the fuel pump to the line going to the needle
valve. Disconnect the fuel line attached to the pressure
fitting of the muffler; your tank is full when fuel begins to
run out of the pressure line. Reconnect the fuel lines to the
needle valve assembly and muffler.
Note: It is very important to reconnect
the lines to the correct place. If they
are reconnected incorrectly, the
engine will not run properly.
