Adding Weights to Correct the Balance
Due to manufacturing differences, it is possible that the
P-51 Mustang ARF may not be balanced properly.
Weights can be added to either the tail or the nose of
your P-51 Mustang ARF if it does not balance properly.
Stick-on weights 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: Balancing Your P-51 ARF
Note: The balance point of your P-51 Mustang
ARF can vary 1/4” forward or rearward
without causing any problems. If your plane
is only slightly out of balance, try placing the
balancing stand towards the nose or tail by
this 1/4” and recheck the balance. If it looks
good and sits level, then you’re good to go!
Flight preparations are the items you must check each
time you travel to the flying field. Because the P-51
Mustang ARF 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 at the field, check to see if there is some form of
frequency control in use. Usually there are clips each pilot
will use signifying the channel their plane is on. This will
prevent other pilots from turning on their radio systems
if more than one pilot is using the same frequency.
Operating two aircraft at the same time on a single
frequency will lead to the demise of one or both aircraft.
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.
Range Check the Radio
A range check should be part of the preflight process as
well. The instructions provided with your radio system
will detail the correct procedure for checking the range
of your particular radio system. This procedure is best
done with a partner to hold your aircraft and check for
any abnormalities.
Fueling the P-51 Mustang ARF
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.
