Control Throws - Hangar 9 Alpha 40 ARF Assembly Manual

Adding Weights to Correct the Balance
Due to manufacturing differences, it is possible that the Alpha
40 ARF may not be balanced properly. Weights can be added
to either the tail or the nose of your Alpha ARF if it does not
balance properly. Stick-on weights (Self Stick Weight, 6 oz
HAN3626) 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.

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.

Up 3/8-inch (10mm)
Down 3/8-inch (10mm)
Aileron Low Rate

Down 1/4-inch (6mm)
Elevator High Rate
Up 1/2-inch (13mm)
Down 1/2-inch (13mm)
Elevator Low Rate
Up 5/16-inch (8mm)
Down 5/16-inch (8mm)
Rudder High Rate
Left 7/8-inch (22mm)
Right 7/8-inch (22mm)
Rudder Low Rate
Left 1/2-inch (13mm)
Right 1/2-inch (13mm)
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, make sure the
safety tubing is slid over the forks of the clevises to
prevent them from opening accidentally in flight.
