JR R-1 OverviewJR's R-1 TRF features a 128 x 64 dot matrix LCD screen with over 8000 points. This allows the display of easy-to-read graphs and function screens, making it simple for racers to adjust throttle curves, brake curves, steering rates, exponential, etc. Five digital trims are intelligently located in easy-to-reach places, even while driving, and are fully programmable as to their function. Trim positions are stored in memory when the R-1 is turned off, so there's no need to worry about steering trim settings after each heat. And then there's that JR feel. The R-1TRF just feels right, encouraging you to take it for a long one-hour main. You'd think all of these advanced features would draw more current, but the R-1 is very energy efficient. NiCds go for nearly three hours on a charge, while alkalines last for over 7 ˝ hours. The R-1 TRF comes with JR's R200 FM or R330 PCM receivers. Both 1 3/8" x 7/8" x 1" receivers weighs just .6 of an ounce - making them JR's smallest competition receivers ever! The R200 & R330 features JR's patented ABC&W technology for interference - free operation. 
Each of five digital trims can be programmed to one of seven functions (static brake, panic brake, steering dual rate, steering trim, ABS swing, ABS point, or AUX 3 channel). Digital trim positions can be displayed both digitally and graphically on a sliding bar graph on the information screen. Two switches can be programmed to select idle up (gas car start up), differing throttle/brake curves, differing steering rate/expo curves, ABS braking and servo speeds.
Dual rates and exponential can be selected and are graphically displayed on the screen. Two dual rate/expo rates can be programmed and selected with a switch. Exponential, normally used to reduce sensitivity around the neutral steering position, is easy to see with the graphic display. Sub-trim allows the servos' centers to be adjusted. Right and left travel adjust is independently adjustable on all channels. Quick throttle eliminates the dead band area where the brakes first start to come in, versus where the throttle first starts to come in. This is especially noticeable when a lot of static brake is used. Trim rates are fully programmable. Idle up advances the throttle for start up. The throttle position and activation switch are fully programmable.
A 5-point throttle curve and a 5-point brake curve are fully programmable, allowing the precise tailoring of throttle/brake feel. Each curve is graphically displayed, and two curves can be programmed. You can graphically set the 9-point programmable throttle/brake curve to adjust throttle and brake responses to match the motor and track conditions.
Servo speed, throttle and steering are fully programmable. Speed can even be independently adjusted in either direction (e.g., turing away from center and returning to center). In addition, a point can be stored at any position, and the servo speed can be individually adjusted on either side of that stored point. Steering tension is adjustable. in addition the progressive springs used get stiffer the farther the wheel is turned. Servo reverse is available on all three channels. Model Reset clears all memory in a selected model and defults back to the factory settings. Three types of modulation are available: PPM (FM), ZPCM (512 PCM) and SPCM (1024).
The Advanced Braking System (ABS) pulse brake is the most advanced braking system available, offering six different user-adjustable parameters. The frequency (pattern) and amplitude (swing) of the pulse can be adjusted. A delay can be programmed in so that pulse braking occurs after a given time. The brake position at which pulse braking begins to function can be programmed, and pulse brakes can be turned on/off via one of two programmable switches. Steering mix can be adjusted to give more pulse braking when turning, and is fully programmable.
The R-1 features the most sophisticated timer available. An up-timer, down-timer and lap timer are programmable. The lap timer records up to 100 laps and displays each lap, best lap and average lap (continually updated). An auto start feature can be programmed to automatically start the timer when trigger is pulled. An alarm will sound at the desired pre-set time, signaling the end of the race/practice session. A navigation system allows a beeper to be pre-set for a specific lap time, allowing the driver to see how close he comes to the ideal pre-set time. The R-1 can store up to 10 models and their trim position in memory. Each model can be named with up to 8 characters. An expert or beginner program can be selected in Tx mode. To avoid confusion, Beginner Mode reduces the programming options to the basics, while Expert mode includes all advanced features. Two programmable mixes are available. A transfer function allows the transferring of memory from one R-1 to another, or from one modelmemory to another. The buzzer tone can be varied: Aux 3 channel activated/inhibited: switch poistion warning advanced/inhibited: digital trim displayed on the intial screen turned on.off. Compatible with JR's DataSafe™, a revolutionary convenience in radio control technology. The PC interface software allows drivers to interface their radio with their Windows 95/98 or NT systems to store an infinite number of models. DataSafe can also save up to 200 models on a standard 3.5" floppy disk. You can even now exchange and e-mail model settings to your driving partner or to any driver across cyberspace who has the DataSafe™ system and your type of transmitter.
A DSC cord allows the radio/servos to be operated without transmitting. A display switch allows the computer to be turned on and programmed without transmitting. Pulg-in modules allow for easy band changes (eg., 27 MHz or 75 MHz). The large 128 x 64 graphic LCD display provides plenty of information, making programming easy to understand.
Logical layout, easy-to-use touch pad. Now includes Transmitter nicad (8N1100SC) and charger.
