XF631 MANUAL Quick Start

XF631 QUICK START

In this manual you will find in-depth instructions that detail all the steps and procedures you should follow in order to program each of the XF631’s features. For modelers who want to get into the air fast, we have provided Quick Start. Quick Start covers the basic programming information necessary to get you airborne. Later, when you want to learn more about specific features

of the XF631, turn to the appropriate pages(s) in this manual for more detailed programming information.

Note: Please charge the system batteries as indicated in step 4.1 before attempting the Quick Start setup and again before flying the model.

Turn on the transmitter and check to ensure that the aileron, elevator, and rudder trim valves are set to the 0 (neutral) position.

Next, set the throttle trim valve to the full low (-40) position by pressing the throttle trim lever down.

Note: Before flying, check that the direction and travel of all control surfaces move correctly.

Before the initial start of your model, please check to ensure that when the Throttle Cut button is pressed, the engine’s carburetor barrel will move to the fully closed (engine off) position.

This safety feature ensures that the engine can be shut off immediately in case of a problem or safety concern.

XF631 MANUAL • INTRODUCTION 1: Using This Manual / INTRODUCTION 2: Features

The XF631 is a full feature introductory computer radio that can be used for airplanes.

A blank data sheet is included at the end of this manual. Once you have input all the necessary data

into your transmitter for a particular model, we strongly recommend that you write that information down on a copy of the data sheet provided. This is to ensure that, in the rare case of a memory failure, you will not lose your data.

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.

XF631 MANUAL • INTRODUCTION 5: Trainer System

The XF631 features a built-in trainer system. The transmitter can be used as either a master (trainer) or as a slave (trainee). The XF631 is compatible with all

other current JR radios that have built-in trainer systems. An optional trainer cord (JRPA130) is needed .

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.
