G. Trim Levers
- The trim levers associated with each control stick are used to correct or (trim-out) the
tracking of the aircraft.
- (Caution) Make sure the trims will move the surface past neutral when moved to their extremes.
This will assure you have adequate trim control.
- After your plane's first test flight, note the positions of the control surfaces that required trim.
Next, center the trims and turn the receiver off. Now adjust the control linkage on the plane
so the surfaces are in the same position before the trim levers were re-centered.
- Turn on the radio and receiver and recheck the control surfaces to ensure that all
the corrections were applied in the proper direction.
D. Servo Reversing
- The Zebra 4 FM transmitter is equipped with servo reversing on all channels.
- If you need to change travel direction of rotation, open the battery case and
move the servo reversing switch.
E. Control Stick Adjustment
- The length of the non-slip control sticks can be adjusted to suit the requirements of the user.
F. Stick Lever Tension Adjustment
- The unique open-stick assembly provides fully adjustable stick tension to adjust
the feel of the sticks in your hands.
- 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.
Using a screwdriver, remove the six 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 and move it to the
under side of the transmitter, carefully turning it as you would turn the page of a book.
Now you'll see the view shown in the illustration.
Using a small Philips 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.
Very carefully reinstall the rear cover. When the cover is properly in place, tighten the six screws.
