FUTABA 8UAFS - Stick Lever Tension Adjustment; Changing the 8 UA Transmitters Mode

11
You may adjust the stick tension of your sticks to provide the “feel” that you like
for flying. To adjust your springs, you’ll have to remove the rear case of the
transmitter. First, pop off the battery cover on the rear of the transmitter. Next,
unplug the battery wire, and remove the battery and RF module from the transmitter.
While you’re removing the RF module, pay attention to the location of the pins that
plug into the back of the module. Next, using a screwdriver, remove the four screws
that hold the transmitter’s rear cover into position, and put them in a safe place.
Gently ease off the transmitter’s rear cover. Now you’ll see the view shown in the
figure below.
Using a small screwdriver, rotate the adjusting screw for each stick for the desired
spring tension. The tension increases when the adjusting screw is turned clockwise,
and decreases for counterclockwise motion.
When you are satisfied with the spring tensions, you may close the transmitter.
Check that the upper printed circuit board is on its locating pins, then very carefully
reinstall the rear cover being careful thread the RF module connector pins through the
hole in the case and not to bend them. When the cover is properly in place, tighten
the four screws.

If you wish to change the mode of the transmitter, say from mode 1 to mode 2, turn
on the transmitter holding the two
buttons down. You’ll see a display
“STICK MODE X,” where X is a number representing the current transmitter mode.
Press the plus (+) or minus (–)
key to change the mode number as desired.
You’ll see the effect of you changes when you next turn on your transmitter. In
some cases, you’ll have to swap the throttle detent mechanism with the elevator
centering mechanism. This can be done by Futaba.
