R700 Slimline Receiver

•

The R700’s extremely compact “slimline” design allows it to fit easily in limited spaces.

•

An independent laboratory ranked the R700 receiver with JR’s patented ABC&W circuitry as one of the best receivers ever tested in terms of 3IM, 2IM, adjacent channel rejection, signal-tonoise ratio, and on-channel capture point.

•

A special “unwanted interference limiter” ignores signals outside of the R700’s band width when the receiver is on and the transmitter is off.

The limiter also prevents servos from random glitching when other transmitters are operating in close proximity.

•

The electrical circuitry in the R700 is state-of-theart surface mount technology (SMT). These SMT components draw less current, thus increasing flying time. Flush mounting of these components also reduces the risk of vibration, wear, and damage.

•

The R700 is compatible with all JR FMtransmitting radios.

XF631 MANUAL • INTRODUCTION 4: Battery Charging

INTRODUCTION 4: Battery Charging

The pilot lamps should always be on during the charging operation. If they are not, make sure you have turned off both the transmitter and receiver.

Do not use the charger for equipment other than JR. The charging plug polarity may not be the same, and equipment damage may 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 compatibilities 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.

CHARGER4.2

It is imperative that you fully charge both the transmitter and the receiver battery packs prior to each day of flying. For the initial charge, leave the charger and batteries hooked up for 20-24 hours in order to fully charge both battery packs to peak capacity. For subsequent charges, leave the charger and batteries hooked up overnight (approximately 16 hours).

The charger supplied with this system is designed to recharge your transmitter battery at a rate of 50mA. The receiver battery pack will charge at 50mA for the 600mAh 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 any other manufacturers’ chargers and radio systems. Beware of improper connections based on “color code” wire leads as they do not apply in this instance. You must make certain that the center pin of your JR transmitter is always connected to the negative voltage for correct polarity hookup.

1. Match the servo reversing, sub-trims, travel adjust, and trims of both radios.

2. Plug the optional trainer cord into both transmitters.

3. Turn on the master transmitter.

Note: The slave radio must be left off.

4. Test all the control functions on your aircraft with the master radio.

5. Push the Trainer button on the master transmitter and check all the control functions with the slave radio.

CHAPTER 1: Transmitter Controls continued

For proper DSC hook-up and operation:

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

2. Plug the optional DSC cord (JRPA132) 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 on the switch harness.

Note: When installing the optional charging jack (JRPA024), 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 airplane without drawing the fully operational 200mAh from your transmitter battery pack. Instead, you will only draw 70mAh when using the DSC function.

Note: You will need to purchase (separately) both the DSC cord (JRPA132) and the JR Deluxe Switch Harness (JRPA001) to make use of the XF631 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 aircraft.

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

There is an eye hook on the front of the transmitter for attaching an optional neck strap (JRPA023). The eye hook is precisely positioned (see Section 1.1)

so that the transmitter will be perfectly balanced when a neck strap is used.

XF631 MANUAL • CHAPTER 2: Connections

It is important to correctly install the radio system in your model. Please read and carefully follow the suggestions listed below.

1. For added protection, wrap the RX and the RX NiCad in foam rubber that is at least 1/4” thick.

2. Run the RX antenna through the fuselage and make sure it is fully extended. Never cut or bundle your RX antenna — this will decrease range and performance.

3. Rubber servo grommets are included with your radio system and should be installed in the servo flanges. The servos should then be mounted on either hardwood rails or a plywood tray with the mounting screws provided. Do not overtighten the mounting screws. The flange of the brass eyelets should face down (toward the wood).

4. All servos must be able to move freely over the full range of their travel. Make sure the linkages

do not impede servo travel. A stalled servo will drain the battery pack within a few minutes.

5. Before installing servo output arms, make sure the servo is in its neutral position.

6. In the case of gas-powered model aircraft, mount the receiver power switch on the side of the fuselage opposite the muffler to protect the switch from exhaust residue. With other types of models, mount the switch in the most convenient place. Make sure that the switch operates freely and is capable of traveling its full distance.

7. With your model sitting on the ground and the

transmitter antenna collapsed, check that your system works at a distance of 75 to 100 feet.

If your system stops functioning at a distance that is shorter than listed above, please contact the Horizon Service Center for further information prior to flying your model.

V-tail mixing combines rudder and elevator for V-tail operations. The Delta wing function allows the aileron to also act as the elevator, while retaining independent use of both functions. The Delta wing function allows the ailerons to also act as the elevator, while retaining independent use of both functions.

Flaperon Setup

When using flaperon mixing, two servos (one for each aileron) must be used. Connect the left aileron servo to channel #6 (Flp/Aux 1) and the right aileron servo to channel #2 (Aile) in the receiver. Individual functions (e.g., servo reversing, sub-trims, etc.) are still available for each of the channels. Use sub-trims for individual neutral adjustment.

Note: When flaperon is selected, it is necessary to reduce the travel adjust values of channel #6 0% in each direction to prevent servo over-travel (binding). Please refer to section 7.3 for travel adjust information.

V-Tail

V-Tail mixing requires two servos. Connect the left tail servo to channel #3 (Elev) and the right tail servo to channel #4 (Rudd) in the receiver. Individual functions (e.g., servo reversing, sub-trims, etc.) are available for each servo. Use sub-trims for individual neutral adjustments described in Section 7.2. V-Tail elevator travel is adjusted by elevator and rudder travel adjust.

Delta Wing Mixing

Delta or elevon mixing, as it is commonly known, is the final wing mixing selection in your XF631. This style of aircraft also employs two wing servos. However, in essence, there is not an elevator present. Instead, at an elevator stick input, the two wing servos function in conjunction with one another in the same direction to create an up/down movement of the aircraft. Also, when an aileron control is given, the two wing servos move in opposite directions to function as ailerons as well.

Dual rate is available for the aileron and elevator channels. The purpose of this function is to allow for in-flight selection of two preset servo travels for each of these channels. The amount of travel is adjustable from 0-125%. The factory settings for both switch positions (0 and 1) is 100%. Either position may be selected as the low or high rate by placing the switches in the desired position and adjusting the value for that position. Different types of maneuvers

require varying amounts of control movements. Snap rolls require large control movements, while smooth maneuvers like long slow rolls are best performed with smaller control movements. Dual rates allow you to change the control movements in flight at the flip of a switch. This allows you to execute maneuvers requiring both radical control movements and small control movements during a single flight.

Accessing the Sub-Trim Function

Sub-trim is an electronic trim that is available for each of the 6 channels. Sub-trim is particularly useful as it allows the digital trim levers to be returned to their neutral positions by adjusting /changing the servo’s neutral position electronically, without the need to mechanically adjust the specific control linkage. This allows the same digital trim lever settings between the two models you can control with this radio system. Sub-trim can also allow additional trim travel when digital trims do not provide enough movement.

Note: It is recommended to use as little sub-trim as possible for adjustment. If more that 20–30 points are required, is it suggested that a mechanical linkage adjustment be performed.

Note: Prior to making final subtrim adjustments, please check to make sure that the digital trim values for aileron, elevator, and rudder are set to the neutral position. Throttle trim value should be set to the -40 position.

1. Turn on the transmitter.

XF631 MANUAL • IMPORTANT INFORMATION

IMPORTANT INFORMATION

Radio controlled models are a great source of pleasure. Unfortunately, they can also pose a potential hazard if not maintained and operated properly. It is imperative that you install your radio control system correctly. Additionally, your level of piloting competency must be high enough to ensure that you are able to control your aircraft under all conditions. If you are a newcomer to radio controlled flying, please seek help from an experienced pilot or your local hobby shop.

Listed below are some safety “Dos and Don’ts” that must be followed by all pilots:

• Ensure that your batteries have been properly charged prior to initial flight.

• Keep track of the time that the system is turned on so that you will have an idea of how long you can safely operate your system.

• Perform a ground range check prior to the initial flight of the day. See the “Daily Flight Checks” section below for information on how to do so.

• Check all control surfaces prior to each takeoff.

• Use frequency flags.

• Do not fly your model near spectators, parking areas, or at any other area that could result in injury to people or damage of property.

• Do not fly during adverse weather conditions. Poor visibility can cause disorientation and loss of control of your aircraft. Strong winds can cause similar problems.

• Do not fly unless your frequency is clear. Warning: Only one transmitter at a time can operate on a given frequency. If you turn on your transmitter while someone else is operating a model on your frequency, both pilots will lose control of their models. Only one person can use a given frequency at a time. It does not matter if it is AM, FM, or PCM — only one frequency at a time.

• Do not point the transmitter antenna directly toward the model. The radiation pattern from the tip of the antenna is inherently low.

• Do not take chances. If at any time during flight you observe any erratic or abnormal operation, land immediately and do not resume flight until the cause of the problem has been ascertained and corrected.

1. Check the battery voltage on both the transmitter and the receiver battery packs. Do not fly below

9.0 volts on the transmitter or below 4.7 volts on the receiver. To do so can cause a crash of your aircraft.

Note: When you check these batteries, ensure that

you have the polarities correct on your expanded scale voltmeter.

2. Check all hardware (linkages, screws, nuts, bolts) prior to each day’s flight. Be sure that binding does not occur and that everything is properly secured.

3. Ensure that all surfaces are moving in the proper manner.

4. Perform a ground range check before each day’s flying session. The range check should be as follows:

• Do not extend the transmitter antenna at this time. Turn the transmitter on.

• Turn the model on.

• Slowly walk away from the model while moving the control surfaces. The aircraft should function properly at a distance of 75–100 feet.

5. Just prior to starting your aircraft, turn off your transmitter and then turn it back on. Do this each time you start your aircraft. If any critical switches are on without your knowledge, the transmitter alarm will warn you at this time.

6. Ensure that all trim levers are in the proper location.

7. Check to be sure that all servo pigtails and switch harness plugs are secured in the receiver. Also, make sure that the switch harness moves completely in both directions.
