Adjust the SENS (gain) dial to a higher percentage for more gain or
lower for less.
NOTE: Dialing back the SENS (gain) dial too far will limit the travel of the servo. The goal is to
adjust the gain so the tail does not wag but holds the yaw axes in all fl ight directions. It’s also
important to note that if you are using a radio system with limited programming capabilities,
this might be the best mode for your application.
Using the gyro in “REMOTE” (SENS ADJ Switch Off )
With the SENS ADJ switch off , you will enter the GYRO menu of your
transmitter to adjust the gain.
To get an idea of how this works, let’s step through setting up the
gyro using the Futaba 6EX radio system in our Heli-Max AXE™ 400.
First make sure your rudder trim setting is centered on the transmitter.
Leave it at center; you do not want to make any adjustments to the
trim with the gyro in heading hold anytime the helicopter is in use.
Check your electronic EPA (end point adjustment) in the transmitter.
To start you want those values (rudder stick left and rudder stick right)
at 100%. To do so, with the transmitter on (the helicopter need not
be powered up for this adjustment), press and hold the Mode/Select
buttons simultaneously. The system will enter the main menu. Press
the Mode button until EPA appears. Press the select button until you
bring up channel 4. Move the rudder stick left to right to view the
end point percentages. Set the value to 100% using the +/- button
if needed.
Setting the Gyro Gain Percentages (Remote Mode)
With the radio on, again enter the main menu by pressing and holding
the Mode/Select buttons simultaneously.
Press and hold to scroll to the GYRO menu. If the GYRO menu is INH
(Inhibited) shift the arrow key positive + and hold until the GYRO
menu says ON or OFF.
Press the select button; here you will see a number percentage with
a small arrow to the left. NOTE: Switch H is the GYRO switch on the
6EX (CH: 5). Flipping this switch ON or OFF will cause a small arrow
to change from up to down based on the position of the switch.
You will also see a plus or negative symbol to the right of the small
arrow. You will use the +/- button located to the right of the screen
to change the gain value.
