Check the Control Throws
One major factor that determines how an airplane handles
in the air is the control surface throw, or how far each control
surface (aileron, elevator and rudder) moves up and down or
left and right. If the throw is too much, the plane will respond
too quickly. If the throw is too little, the plane will respond too
slowly. The control throws in the Sensei have already been
determined by where the pushrods are connected to the servo
arms and the control surfaces and by how far the servo arms
rotate. But, if you are using a radio control system different
than the Tactic TTX600, the servo arms could rotate more or
less than anticipated, changing the throws. Therefore, it’s a
good idea to double-check the throws just to make sure they
are acceptable. Follow the procedure below to make sure the
control throws are properly set.
Measure the elevator throw fi rst:
❏
1. Still without the propeller mounted on the motor, switch
on your transmitter and connect the motor battery. Check that
the dual rate (D/R) switch is in the up position (high rate). With
the switch in the up position the servo arm travel is 100%.
This rate allows the plane to be more responsive in certain
maneuvers. With the switch in the down position (low rate),
the servo arm travel is 60% of full travel. This rate allows for
smooth basic fl ying and is good for the beginner who is just
learning to fl y.
❏
2. Place a ruler next to the trailing edge of the elevator at
the widest part (from front-to-back).
❏
3. Use the transmitter to move the elevator up and measure
the distance it moved from center. This is your “up” control
throw. Measure the down elevator control throw following the
same procedure. Compare the up and down elevator throw
to the recommended elevator throw below. Measure and
compare the rudder and aileron throws as well.
These are the recommended control surface throws:
5/8" [16mm]
Right & Left
1/2" [15mm]
Up & Down
AILERON
1/2" [15mm]
Up & Down
RUDDER ELEVATOR
Note: If you ever install different servos in the plane or use a
different radio control system, make sure you check that you
still have the recommended control throws.
