JR XF631

Model Airplane News, Jan 2001 by Chianelli, Chris

6-channel simplicity

Easy operation was a prime design directive with JR's all new JR XF631; the only programming functions it has are the ones used most by modelers, such as dual rates, travel adjustments and subtrims. The XF631 also offers 3-model memory and is preprogrammed with three types of wing mixes (standard, flapperon, or delta/elevon). The programming switches are conveniently placed below the main power switch within easy reach for better control. JR provides everything you need in a flight pack. The XF631's flight pack includes the new, lighter, narrower 8700 receiver and four of JR's new 537 standard BB servos, which have 1/3 the deadband of the S517

for improved accuracy. Don't like to mess around with more complicated 6-channel radios? You'll have more fun-and more flying time-with JR's XF631.

Also shown, and available separately, is the new JR 8700 Slimline FM receiver that has one more channel than the 8600 yet is slimmer in design and weighs about 1 ounce. As with all JR FM receivers, the 8700 features the excellent interference protection of JR's patented ABC&W circuitry. The 8700 is compatible with any current JR FM aircraft system and will be the standard receiver included with new JR FM systems.
