Your Cox ICON RC 3 channel FM transmitter has been designed for comfort and a positive feeling of control. From the stylish and ergonomical curvature of the case to the conveniently placed, precision molded 2 axis gimbal, the Cox ICONRC™transmitter is meant to fit in your hand and provide the control authority you’d expect from an industry leader. OFF/ON Switch Power LED’s Tx Antenna Ch 2 Trim Ch 1 Trim 2 Servo reversing is a useful feature if the installation of your servos does not allow for the correct movement relative to the control stick input. To adjust, use a small screwdriver and flip the switch in the direction opposite the current setting and note the direction of movement of the control surface. There is no servo reversing for the 3rd channel. If you should choose to replace the 8 AA Alkaline batteries with rechargeable NiCads, the Cox ICON RC™ transmitter has a charge jack located on the bottom rear of the transmitter case. Make sure that the charger and batteries are suitable for this application. Do not charge non-rechargeable batteries. WARNING:Any adjustment(s) to your RC transmitter or replacement of transmitter components (crystal, semiconductor, etc.. that may result in modifying the power, range or frequency of your transmitter is a violation of FCC regulation and voids your authority to operate the transmitter . If you require a dif fer - ent operational frequency, please return the transmitter and receiver to Cox Hobbies for professional replacement and tuning. 7 “V” Tail Mixing 63 “V” tail mixing is the electronic coupling of the rudder and elevator to the 2 axis control stick. Since a “V” tail airplane requires input from both “ruddervators” for coordinated turns, the transmitter handles all of the electronic mixing of Ch 1 and Ch 2. The switch is either on or off. To turn on, use a small screwdriver and slide the switch toward the ON position. Controlling the up and down, right and left movement of a “V” tailed airplane is a little different than found on a cruciform (conventional rudder/elevator) model. Please refer to the images (as seen from the rear of the model) and directions below to properly set up your “V” tail equipped model. If required, use the servo reverse switches to get the correct direction of each control surface. If that fails to correct the problem, it may be necessary to reroute your control linkages.

Airplane RIGHT TURN - left ruddervator moves UP, right ruddervator moves DOWN. Airplane LEFT TURN - right ruddervator moves UP, left ruddervator moves DOWN. Receiver The COX ICON RC™ 3 channel 2 in 1 receiver is a single conversion, highly selective, light weight FM design with several sophisticated features. In addition to the 2 servo, 3 pin servo plug, the ICON RC 2-in-1 receiver features a built-in Battery Elimination Circuit (BEC), that supplies a safe 5V to your servos using a 6 cell (7.2V) battery pack. The ICON RC 2 in 1 receiver also has an Electronic Speed Control (ESC), that allows a full range of power settings to the flight motor . The high-current MOSFET motor driver is capable of supplying up to 10A of continuous motor current. In addition, the ICON 2 in 1 receiver includes a voltage sense circuit that automatically shuts off the motor when the battery pack has dropped to approximately 0.9V per cell. This allows a safe margin of remaining…

Technical Description of The COX ‘ICON’ Transmitter Product M45054064 The COX ICON transmitter is a frequency shift modulated digital proportional design intended for use in the 72MHz model radio control band. Under previously established rules of operation, it is intended for controlling model aircraft only. It is designed for use on any of the fixed 50 channels within the 72.0MHz to 73.0MHz band. The transmitter circuitry consists of four primary sections. These include the MCU digital encoder, the FSK modulator, the RF section, and the antenna matching and harmonic trap circuitry. The antenna for the unit is a collapsible 7-section type, 1.1 meter in length. Eight 1.5V AA alkaline batteries for a total of 12 volts power the transmitter circuitry. A 5-volt regulator maintains voltage stability for all circuitry with the exception of the RF power amplifier. In production, the oscillator crystal is permanently affixed and not removable per FCC regulations. All circuitry is mounted to a single-sided printed circuit board which is mounted inside a hand- held molded plastic housing. The removable antenna is mounted to, and extends through an opening molded into the top of the molded plastic housing. A two-axis gimbaled control stick is mounted to the right of center of the face of the molded housing. The control stick provides user input commands to the MCU encoder with the rotation of two potentiometers. A third control input potentiometer is located in the back of the molded housed to the left of center. These locations are chosen for best ergonomic control inputs from the model flyer. Three battery condition LEDs are located near the center and top of the face of the molded housing. The ON/OFF switch is located near the center and bottom face of the housing. The non-removable crystal, and three function slide switches are mounted in the back of the housing near the bottom. The removable battery holder installs from the bottom of the housing and is held in place using a molded latch. The COX ‘ICON’ transmitter is a 3-Channel unit, offering three different control functions for the model flyer to control his aircraft. The three are typically elevator, ailerons, and throttle. In operation, the control input potentiometers vary the spacing between four information modulation pulses. The nominal spacing for all three channels is designed to range from 1.0ms to 2.0ms, with 1.5ms as the neutral position. A microprocessor with a crystal-controlled clock maintains accuracy for the pulses. The four information pulses are a nominal 300us in width, and are passed to the FSK modulator. The FSK modulator varies the forward voltage of a varicap diode. The varicap diode in turn varies the oscillation frequency of the RF oscillator circuitry by 3kHz. A fundamental crystal is the active component that provides the basic frequency. To achieve the final 72MHz frequency at the RF power amplifier, this frequency is multiplied by five. The RF power amplifier increases output power to be input to the antenna matching circuit. This circuit also provides harmonic trapping. The RF level is then fed to a base-loaded 1.1 meter long collapsible antenna.

Tuning Procedure For COX ICON FM Transmitter Operating In the 72-73MHz Model Aircraft Frequency Band The Transmitter Please note that there are two specific areas of interest on the schematic titled COX HOBBIES ICON TRANSMITTER M45054064 having to do with the tuning of this transmitter. 1. The variable resistors VR2 and VR3 associated with transistor Q4 control the width of the frequency modulation for the oscillator Q3. 2. Tuned coils T2 through T5 are used to optimize and tune the transmitter to the specific operating frequency, while tuned coil T1 and its associated components form a harmonic trap. After final assembly, the transmitter is prepared for tuning by temporarily placing a ‘fake’ plastic case back onto the unit, installing the antenna, and installing a battery holder with 8 fresh alkaline batteries. The ‘fake’ case back has holes drilled in it corresponding to the five tuned coils. This allows the technician tuning the transmitter to grasp it for hand capacitance while inserting a ceramic tuning wand through the holes to adjust the coils. The removable case back also allows access to the modulation circuitry during alignment. When the tuning procedure is complete the ‘fake’ case back is replaced with a non-drilled production piece and screwed in place. The Alignment Equipment The tuning procedure for this transmitter is carried out within a screen room. The alignment equipment includes the following; 1. Frequency Counter 2. Spectrum Analyzer 3. FM/AM Modulation Meter 4. FM/AM Signal Generator (reference if needed) 5. High Frequency Oscilloscope Note that the frequency counter connected to the high frequency oscilloscope to observe all transmitter frequencies and frequency changes during alignment. Measurements are done by way of RF proximity link. The spectrum analyzer is set for split-screen operation to show the primary levels for the 72-73MHz frequencies, and the second 144-145MHz harmonic. The Tuning and Alignment Procedure Once the ‘fake’ case back and battery pack is installed in the transmitter, the telescoping antenna is fully extended, and the unit is switched on. 1. Grasping the transmitter with one hand, tune coils T5, T4, T3, and T2 for maximum RF level for the assigned frequency. 2. Coil T1 is then tuned for minimum second harmonic 144-145MHz power level. 3. Steps #1 and #2 are repeated three times in rapid succession. 4. Modulation control transistor Q4 is then shunted off. 5. The FM/AM modulation meter is then connected to the antenna. 6. Variable resistor VR3 is then adjusted for the primary 72-73MHz operation frequency. 7. Transistor Q4 is then shunted to the on position. 8. Variable resistor VR2 is then adjusted for a frequency shift from the primary operating frequency of –3KHz. 9. The shunt for transistor Q4 is then removed. 10. Normal frequency shift operation for the design from the encoder circuitry is then viewed on the modulation meter as the last tuning procedure. 11. The transmitter is removed from the alignment environment, the ‘fake’ case back, and the battery supply are removed. The correct production case back is then installed with four screws.
