X-378 MANUAL Introduction

In the beginning of this manual you will find the specifications for the radio and its various accessories. In addition, guidelines for the initial installation of the accessories have been included, as well as instructions for setting all the functions and programs of the X-378 to suit your personal preferences. These features are discussed in the same order that they will appear on your radio, as you will see on the accompanying charts. An explanation of the use and purpose of each feature is provided, followed by a labeled illustration of its respective LCD display.

In addition, a step-by-step example clarify the setup procedure of the feature. Practical applications for many of the radio’s features enable you to see their true purpose and additional possibilities. A blank data sheet has been included at the end of each

section. Once all data has been input for a particular model, it is highly recommended that you record it on a copy of the sheet provided. If you should experience memory loss or battery failure or want to make changes to the current settings, this step will save you a great deal of time. Following the data sheet, you will find information on precautionary measures and general guidelines for safe use of your new equipment.

Use of the Instructions with the Radio

While the X-378 has a dedicated or single-use switch layout, it may be used for multiple model types. Templates have been provided in this manual that explain the different switch assignments when using the transmitter with the various air, heli and sailplane software.

The computer designed, ergonomically styled transmitter case ensures a good, comfortable fit in your hands. The ultra-precision control sticks offer adjustable spring tensions and length. The throttle stick offers a ratchet in Airplane configuration for smooth travel. 8-model memory storage allows programming of all characteristics of eight separate helicopters, airplane or gliders; you can program more than one setup for a single aircraft, allowing you to instantly change the flight characteristics.

A five-year lithium backup battery prevents loss of memory in the event that the battery discharges completely or is removed.

Features include automatic fail-safe "set" and information update in PCM mode when fail-safe is used. A programmable trainer function allows the student to practice individual channels separately. Direct Servo Control (DSC) permits operation of all the controls and servos without generating a radio signal.

X-378 MANUAL Introduction

Note:

It is imperative that you fully charge both the transmitter and the receiver battery packs prior to each flight. To do so, leave the charger and batteries hooked up overnight (16 hours). The first charge should be approximately 20–24 hours in order to fully charge both battery packs to peak capacity.

The charger supplied with this system is designed to recharge your batteries at a rate of 5mAh for the transmitter and 50mAh for the receiver battery pack.

Transmitter Only

The center pin on all JR Remote Control Systems is negative. Therefore, the center pin on all JR chargers is negative, not positive. This is different from many other manufacturers' chargers and radio systems. Beware of improper connections based on "colorcoded" wire leads, as they do not apply in this instance. You must make sure that the center pin of your JR transmitter is always connected to the negative voltage for correct polarity hookup.

Important: Please note that the charging polarity of the transmitter and receiver are different.

CHAPTER 4: BA TTER Y CHARGING

TRANSMITTER/RECEIVER

4.1

The pilot lamps should always be on during the charging operation. If not, check to make sure that both the transmitter and receiver are switched off. Do not use the charger for equipment other than JR. The charging plug polarity may not be the same. Equipment damage can result.

Do not use other manufacturers' after-market accessories that plug into the transmitter's charging jack. If you do, any damage that results will not be covered by warranty. If you are unsure of compatabily issues with your radio, seek expert advice before

doing anything to avoid possible damage. During the charging operation, the charger's temperature is slightly elevated. This is normal. Also, note that the voltage shown on the charger is higher than the battery in use. This voltage cannot be measured with a voltmeter. Only current can be measured with any accuracy using this type of charger.

Be sure to use the proper charger (120mAh) when using battery packs of 1000mAh or larger for

your receivers.

Your new X-378 system employs four digital trim levers for unmatched precision and adjustability. By using the Trim Step function located in the System mode, the movement of the ADT trims can be fine tuned as needed to match your specific application.

The ADT feature is also designed to automatically save the determined trim values for each model. When the X-378 is changed between models in the Model Select function, the digital trim values will automatically stay with each model, eliminating the need for a separate trim memory function.

The X-378's digital trims also feature the Direct Access display function. While at the Normal display screen, if a trim lever is moved, the screen

will automatically change to display the numeric value, as well as the graphic position for the trim being adjusted.

The X-378's digital trims also feature 2-speed scrolling . When a substantial amount of trim is required, holding the trim in the desired position will activate the dual speed scrolling function. The X-378's Aileron, Elevator, and Rudder trim levers (also throttle in sailplane mode) feature an audible center trim beep. This is helpful in determining the trim levers center position during flight.

Please also note that unlike conventional mechanical trim levers, when the X-378 transmitter is in the off position, no changes can be made to the trim values during transportation.

The X-378 also features a revolutionary One-Touch Digital Throttle Trim lever. While in Air or Heli modes, the X-378 will remember the maximum high Throttle Trim position (usually idle) set from the previous flight. At the end of the flight, move the Throttle Trim to the full low (engine off) position. For the next flight, by simply pressing the Digital Throttle Trim up once, the throttle trim value will automatically move to the position from the previous flight. Trim value changes can then be made by moving the throttle trim lever as needed.

The Direct Access Digital Trim function will display

the throttle trim value numerically and also

graphically on the screen automatically each time the Throttle Trim is moved

This feature is very helpful as once you have set the correct throttle trim value for a proper idle, the X-378 will allow the Trim lever to be set back to this position for each flight, eliminating the need to set the exact throttle trim value for each flight.

Note: When the X-378 is in the glider (sailplane) model type, the Digital Throttle Trim works as a conventional trim lever, which is the most desirable method in this mode.

DIRECT SERVO CONTROL (DSC)1.6

CONTROL STICK LENGTH ADJUSTMENT1.4

To adjust the stick length, use the 2mm Allen wrench (supplied with your X-378 transmitter) to unlock the set screw. Turn the wrench counterclockwise to loosen the screw. Then, turn the stick clockwise to shorten or counterclockwise to lengthen. After the control stick length has been adjusted to suit your flying style, tighten the 2mm set screw. If you desire longer sticks, JR offers a thicker stick (JRPA047) that is approximately one inch longer than the standard stick. This stick, crafted from bar stock aluminum, is available at your local JR dealer.

For proper DSC hook-up and operation:

1. Leave the transmitter power switch in the Off position. The transmitter will not transmit any radio frequency (RF) in this position.

2. Plug the (supplied) DSC cord into the DSC port in the rear of the transmitter.

3. The encoder section of the transmitter will now be operational and the LCD display will be lit.

4. Plug the other end of the DSC Cord into the receiver charge receptacle. Turn the switch harness to the On position.

Note: When you install the charging jack, be sure to hook the charging jack receptacle securely into the switch harness charge cord.

Why you should use the DSC function:

1. The DSC enables you to check the control surfaces of your aircraft without drawing the fully operational 200mAh from your transmitter battery pack. Instead, you will only draw 70mAh when using the DSC function.

2. The DSC function allows you to make final adjustments to your airplane without transmitting any radio signals. Therefore, if another pilot is flying on your frequency, you can still adjust your aircraft and not interfere with the other pilot’s aircraft.

Note: Under no circumstances should you attempt to fly your aircraft with the DSC cord plugged in! This function is for benchchecking your airplane only.

An eyelet is provided on the face of the X-378 transmitter that allows you to connect a Neck Strap (JRPA023). This hook has been positioned so that your transmitter has the best possible balance when you use the neck strap.

Note: Double-check to ensure that the neck strap is securely fastened to the transmitter.

BASE LOADED ANTENNA

FREQUENCY NOTES/AIRCRAFT ONLY FREQUENCIES

1.8

An optional base-loaded antenna is available for use with the X-378 transmitter. It is considerably shorter than the standard antenna. However, the base loaded antenna cannot be collapsed for storage in the side of the transmitter. You must also use an

adaptor (JRPA156) to attach the antenna to your X-378. The Base Loaded Antenna (JRPA155) is made of a flexible coil and is covered with a soft plastic material. Your range will not be affected when using the base loaded antenna.

1.9

The X-378 transmitter employs a plug-in crystal for transmitter that is glued in place at the time of shipment. Per FCC regulation, the transmitter crystal should only be changed by a certified technician. Changing of the transmitter crystal by a nonauthorized technician could result in a violation of FCC rules.

The X-378 can transmit in either Pulse Code Modulation (PCM) or Pulse Position Modulation (PPM, commonly referred to as FM).

Be certain to observe the following guidelines:

1. Do not operate your transmitter when another transmitter is using the same frequency, regardless of whether the second transmitter is PCM, PPM (FM) or AM. You can never operate two transmitters on the same frequency simultaneously without causing interference to both receivers and crashing both aircraft.

2. For operation of your X-378 with additional receivers, you should refer to the receiver compatibility chart. The chart is located in the

Modulation Selection Section of this manual.

Aircraft-Only Frequencies

JR Transmitters and receivers are available in 72MHz frequencies in the United States for use with model aircraft. Employing 72MHz frequencies does not require a special operator’s license from the Federal Communications Commission (FCC).

* A chart for all available frequencies is located on

page 185 of this manual.

X-378 MANUAL Airplane

CHAPTER 2: CONNECTIONS • Airplane

It is extremely important that your radio system be correctly installed in your model. Here are a few suggestions on the installation of your JR equipment:

1. Wrap the receiver in protective foam rubber that is no less than 3/8 inch thick. Secure the foam to the receiver with #64 rubber bands. This protects the receiver in the event of a crash or a very hard landing.

2. The servos should be mounted using rubber grommets and brass bushings to isolate them from vibration. Do not over-tighten the mounting screws; this will negate the vibration absorption effect of the rubber grommets. The following diagram will assist you in properly mounting your servo.

The brass bushings are pushed from the bottom up in the rubber grommets. When the servo screw is tightened securely, it provides the proper security as well as the proper vibration isolation for your servo.

3. The servos must be able to move freely over their entire range of travel. Make sure that the control linkages do not bind or impede the movement of any of the servos.

4. Mount all switches away from the engine exhaust and away from any high vibration areas. Make sure the switch operates freely and is able to operate over its full travel.

5. Mount the receiver antenna firmly to the airplane to ensure that it will not become entangled in the

propeller or control surfaces.

BACKUP ERROR DISPLAY4.2

All preprogrammed data is protected by a five-year lithium battery that guards against main transmitter battery failure. Should the lithium battery fail, the display will indicate ERR1 regardless of the position of the On/Off switch. If this occurs, it will be necessary to replace the battery and reprogram all data. All transmitter programs will return to the factory default settings, and the data you have input will be lost. When it becomes necessary to replace the lithium back-up battery, contact JR Horizon

Service Center. Due to the possibility of extensive damage caused by improper removal or replacement, only JR Horizon Service Center is authorized to make this change.

The Trim Step function allows the user to increase or decrease the coarseness of the servo movement as compared to the steps or beeps of the digital trim. The total servo trim movement remains the same, (approx. 30degree) regardless of the trim step rate selected(1~10). The factory default setting for the trim step function is 4, which means that for each

step (beep) of the digital trim, the servo will move in digital increments of 4. In other words, if a finer trip step value of 1 is selected, the servo will move in a digital increment of 1for each step (beep) of the digital trim. If a more coarse trim value of 10 is selected, the servo will more in a digital increment of 10 for each step (beep) of the digital trim lever.

4. Plug the left wing aileron servo into the Auxiliary 1 (AUX 1) port of your JR receiver. Connect the right aileron servo into the aileron port (AILE) of your receiver.

5. Check to make sure that the wing servos move in the proper direction. For a right turn, the right aileron should raise while the left aileron lowers simultaneously. For a left turn, the opposite is true; the left aileron should rise while the right aileron drops. If your servos are not moving in the direction just described, use the Servo Reversing function to reverse the travel direction of the servo(s) that are moving improperly. Refer to the Servo Reversing section for information on how to reverse the travel direction.

Note: Each servo's travel direction is adjusted individually through the Servo Reversing function.

Once the servos achieve their proper travel direction, adjust their travel volume, dual rates, sub-trim and aileron differential.

Note: The applicable channel's left or right travel adjustment may be made individually by accessing the Travel Adjust function. Refer to the Travel Adjust section of this manual for more information. The fine adjustments of your aileron controls should be made in the Dual-Rate function. Refer to the DualRate section for information on how to do so. You can also adjust the neutral point of your aileron servos individually through the use of the Sub-Trim function. Refer to the Sub-Trim section of this manual for more information.

Delta Wing T ype Selection

Delta or Elevon is the final Wing Mixing selection in your X-378. This style of aircraft also employs two wing servos. However, there is not an elevator present. Instead, at an elevator stick input, the two wing servos function in conjunction with one another to create an up/down movement of the aircraft. The

wing itself functions as if it were the elevator. Also, when an aileron control is given, the two wing servos move in opposition to one another to function as ailerons.

1. While the Down and Channel keys are pressed, move the power switch to the On position to access the System mode.

2. Press either the Up or Down key until "WING" appears in the left portion of the LCD. The current wing type will be displayed on the upper center portion of the LCD: NORM-Normal; FLPERFlapperon; DELTA-Delta (Elevon).

3. Press either the (+) or (-) key to select the Delta (Elevon) Wing Type function.

Note: With the Delta function, one servo must be used for each elevon, i.e., a separate servo for each wing half.

4. Plug the left elevon servo to the aileron (AILE) of your JR receiver. Connect the right elevon servo into the elevator (ELEV) port of your receiver.

5.Check to make sure that the servos move in the proper direction. When an input is given from the elevator stick, they should move in unison to achieve the proper up/down elevator command. If your servos do not move in the proper direction as described above, use the Servo Reversing function to reverse the travel direction.

Note: Each servo's direction is adjusted individually through the Servo Reversing function. For more information, refer to the Servo Reversing section in this manual.

6. Once the servos have achieved their proper travel direction, adjust their travel direction, travel volume, dual rates, sub-trim and aileron differential.

Note: The applicable channel's left or right, up or down travel adjustments can be made individually. Refer to the Travel Adjust section in this manual for more information.

7. Relative to the note above, each servo's travel volume is automatically reduced to 75% of the operating range. This is to ensure that the servo does not operate beyond its capabilities. Failure to observe extreme caution when adjusting the value for the elevon servos may result in damage to the servos by over traveling.

Note: Fine adjustments of the elevons should be made in the Dual-Rate function. For more information, refer to the Dual-Rate section in this manual. You can also adjust the neutral point of your elevon servos individually. To do so, use the Sub-Trim function as described in the Sub-Trim section of this manual. Differential is offered for the elevon function of your XP-783. For more information, refer to the Differential Aileron Mixing section of this manual.
