R/C SAFETY PRECAUTIONSFor safe and reliable performance of your R/C model, please care-fully read and follow these guidelines:1. Radio control models are not toys. They are capable of inflict-ing serious injury to people and property. Use caution at alltimes when operating your model.2. You are responsible for the safe operation of your R/C model.You must properly install, test, and operate your model with aclear sense of that responsibility. Do not take risks that mightendanger yourself or others. 3. Running an R/C car in the streets is very dangerous to bothdrivers and models. Avoid running your model in areas occupied by full-size automobiles. To locate areas where youcan safely operate your model, contact your local hobby shopfor R/C tracks or clubs in your area.4. When running an R/C boat, keep it away from any swimmers,full-size boats, or wildlife. Also, watch carefully for fishinglines that can entangle the propeller.5. Before operating your model, make sure your frequency isclear. If someone else is operating on the same frequency, bothmodels will go out of control, possibly causing damage to themodels, as well as others.6. If at any time while operating your R/C model you senseabnormal model functioning, end your operation immedi-ately. Do not operate your model again until you are certainthe problem has been corrected.CAUTION: Control of your model is impossible without suffi-cient voltage for the transmitter and receiver. A weak transmitterbattery will decrease your range of operation and a weak receiverbattery will slow servo movement and decrease your range ofoperation. Check your receiver pack voltage often to avoid losingcontrol of your model. When using a model that operates boththe electric motor and the receiver from the same battery(Battery Eliminating Circuitry or B.E.C.), you should discontinueuse when the top speed sharply decreases or you will quicklylose control of your model.I. INTRODUCTIONCongratulations on your purchase of the JR Python2-channel radio control set which has been manufactured andassembled with the greatest care.We are confident that you will be delighted with your purchase.Please read the instructions thoroughly, noting all points beforeuse, in order to avoid mistakes in handling and operation.
Your NER-102 Receiver has Battery Eliminator Circuitry (B.E.C.).The receiver gets its power from the model’s NiCad battery pack,thus saving the weight of an additional receiver battery. NiCadbatteries from 6V-8.4V (5-7 cells) can be used safely. Higher volt-age packs may damage the receiver and servos.ATTENTION: Make sure the male and female connectors havethe correct polarity (+/–) before connecting. The servo lead andreceiver case are molded so that the lead can only be insertedcorrectly. Be sure to orient the servo plug correctly for properinsertion.You may use a separate battery to power the receiver (such asfor some electric boats or in gas-powered vehicles). A NiCad packplugged into the BATT socket on your receiver will operate yourreceiver. You may also use alkaline batteries with an optionalbattery holder (part no. JRPA020).If you use a mechanical speed controller, please ensure that ithas the correct connector for a B.E.C. system (red connector).See FIGURE A for a typical setup.Most electronic speed controllers are set up for B.E.C. operationand plug directly into your receiver (Function 2). See FIGURE B fora typical setup and check your speed controller’s manual for correct installation.You should use the black rubber servo cushions whenever possi-ble to decrease your servo’s sensitivity to vibration.IV. OPERATING YOUR MODELIt is important to learn the proper sequence for switchingON/OFF your radio system:BEFORE OPERATION: Switch on the transmitter, then the receiver.AFTER OPERATION:Switch off the receiver, then the transmitter.This ensures that you will always have a signal to the receiver,and your R/C model will not operate out of control when youturn off the transmitter.V.

VI. IDENTIFICATION OF TRANSMITTER PARTSPYTHONLED VOLTAGE METER – If the meter indicatesgreen, your batteries are approximately fullstrength. If the meter indicates orange or red,the batteries are weak and need to be replacedwith new cells or charged if you are usingrechargeable “AA” NiCads.STEERING REVERSING SWITCHTHROTTLE REVERSING SWITCHPOWER SWITCHCRYSTALSTEERING WHEEL –The steering wheelrotates 35° to the leftand to the right.STEERING TRIM – Rotate the top trimtab to adjust and obtain the neutralposition of the steering servo.HINT: Setting your steering linkage:1. Make sure your steering rateadjuster (see call-out at right) is set tothe maximum position and your steering trim is centered.2.Turn on the power to your receiverto center the steering servo and setthe linkage for maximum travel. Thenuse the rate adjuster to adjust theamount of travel you need.THROTTLE TRIM – Rotate the bottomtrim knob to adjust and obtain theneutral position of the throttle servo.CHARGING JACK – Your Python trans-mitter can be upgraded to NiCad batteries using the optional DynamiteDYN1900 NiCad Conversion Kit.JR POLARITY:(Center pin negative)STEERING RATE ADJUSTER – The steering rateadjuster affects the throw of the steering servo.The output can be adjusted from approxi-mately 10% to 100%. The throw of the servodecreases as you move the dial to the left.HINT: Use this to decrease the sensitivity ofyour steering on loose courses and on courseswithout tight curves.SERVO REVERSE SWITCHES– The reverse switches allow the rotation of the servos to be reversed.35°35°20°20°THROTTLE TRIGGER – The throttle trigger moves20° in the forward and reverse direction.BACK OF TRANSMITTER(FACTORY INSTALLED)BATTERY CASE – To removethe battery cover, slide thetab in the direction of thearrow while pushing therounded tab. Install the 8 “AA” batteriesaccording to the diagram.If the transmitter voltagefails to register, check forthe correct installation ofthe batteries and makesure the batteries still havea charge.3
