Section 14:
Control Throws

Step 1
Check the battery voltage on both the transmitter and
the receiver battery packs. Do not fly below 4.3V on the
transmitter if you are using a Spektrum transmitter that uses
4-cells to power the transmitter. Do not fly below 9.5V on the
transmitter if you are using a JR or Spektrum transmitter that
uses 8-cells to power the transmitter. Do not fly if the receiver
pack is at or below 4.7V. To do so may crash your aircraft.

Step 2
Check the movement of the elevator with the radio system.
Moving the elevator stick toward the bottom of the
transmitter will make the airplane elevator move up.

Step 3
Check the movement of the ailerons with the radio system.
Moving the aileron stick right will make the right aileron
move up and the left aileron move down.

Step 4
Use a ruler to adjust the throw of the elevator, ailerons
and rudder.

note
: Measurements are taken at the inner or widest
point on the control surface.
These are general guidelines measured from our own flight
tests. You can experiment with higher rates to match your
preferred style of flying.
note : Travel Adjust, Sub Trim and Dual Rates are
not listed and should be adjusted according to each
individual model and preference.
once all control throws are set, shrink the tubing
at all the clevises to keep them from opening
up during flight. use caution not to damage the
covering around the control horn by applying too
much heat.
Section 15:
Flight Preparations
Flight preparations must be checked each time you travel to
the flying field. Because your model 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 your Model
Fill the fuel tank with the proper fuel. Fill the tank by
connecting the fuel pump to the line going to the needle
valve or to the fuel dot on the side of the cowling.
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 or insert the plug into the fuel dot and connect the
line to the 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.
