B. Layout
• (Show drawing and point to features)
C. Specifications
• Operating system: Two stick
• Power supply: 9.6V (8 cell) Nicad battery
• Current drain: 150mA
• Output power: 500mw
• Modulation: PPM (FM)
D. Servo Reversing
• The Laser 4 FM transmitter is equipped with servo reversing on all 4
channels.
• (Show Illustration)
• (Note: Leaving the switch in the middle will cause the radio to work
erratically so please make sure that the switches are all pushed to the
furthest end.)
E. A.T.V. (Adjustable Travel Volume)
• CH 1 & CH 2 only
• This function adjusts the servo overall throw from left to right on CH 1
and up and down on CH 2.
• The rate setting is from 30% -110%
(Show Illustration)
F. Mixing • The Laser 4 is equipped with mixing for V-tail (CH2 & CH4) or Elevon
(CH1 & CH2) for use with flying wing or V-tail type aircraft.

G. Control Stick Adjustment
• The length of the non-slip control sticks can be adjusted to suit the
requirements of the user.
• See Illustration.
(Show Illustration)
H. Gimble Tension Adjustment
• The unique open-stick assembly provides fully adjustable stick tension to
adjust the “feel” of the sticks in your hands.
• Turning the adjustment counter clockwise will reduce or “soften” the stick
tension while turning it clockwise will increase or “stiffen” the tension.
• See Illustration.
(Show Illustration)
I. Trim Levers
• The trim levers associated with each control stick are used to correct (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
• During the initial 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 are 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.

4. Charging Specifications
A. Transmitter/Receiver battery
• The initial charge on your system should be at least 24 hours to insure a full
charge.
• Subsequent charges should be at least 12 - 20 hour.
• It is best to put you system (TX and RX) on charge the night before you plan to
use it.
• To charge your batteries first make sure your transmitter and receiver are off; then
connect the wall chargers outputs to the charging jack on the transmitter and the
charge receptacle on the switch harness or directly to the battery. Make sure the
green (TX) and red (RX) light comes on. If it does not check for proper
connection and/or power to the outlet.
• Be careful not to leave your transmitter on charge for more than 24 hours to
prevent any damage to the battery or charger.
• Always charge your system before you go out to fly.
