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.

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.
H. Reading the LED Battery Indicator
-There is one indicator lights on the face of the radio marked High and Low (blinking).
-These relate to the condition of your transmitter battery. Please pay attention to these
LED lights and stop flying when the LED light is blinking.
2. BATTERY INSTALLATION
- The transmitter requires six and the receiver battery pack needs four AA size batteries.
These can be Alkaline, Ni-cad or Ni-Mh cells
- When loading the batteries, make sure the receiver and transmitter switches are in the "off" position.
- Open the battery door in the back of the transmitter by pressing the tab on the
bottom of the battery door and lifting up.
- Load batteries into the appropriate slots, taking care to install according to the
proper polarity.
- Replace the battery door and turn the power "on".
