JR XP662: An affordable, programmable radio for airplanes and helicopters!

Model Airplane News, Oct 2002 by Aberle, Bob

Most JR transmitters have an internal lithium battery that maintains the overall computer system memory. This battery is rated to have a life of about 5 years; after that, you should send in your transmitter for a battery change, general cleaning and maintenance check (this is a good idea for any RC transmitter).

As already pointed out, the XP662 system can be programmed for fixed-wing or helicopter flying. Two switches at the top left and right corners of the case have different functions, depending on whether you are set up for fixed-wing or helicopter operation. The left switch controls retractable for aircraft and "flight mode" for helicopters. The right switch is a flap or mix switch for aircraft or a "throttle hold" function for helicopters. JR provides decals that you can put next to each switch to help identify the shared functions.

The airborne components of the XP662 system include a 0.65-ounce JR R700 receiver, four NES-537 servos and a 4-cell, 600mAh Ni-Cd pack. Total weight of the airborne pack is 10.1 ounces.

SUMMARY

I like this new XP662 radio very much-- especially its six model-memory positions and optional fixed-wing or helicopter operation. It's a full-coverage RC system that's suitable for pilots of any flying skill level. It is very simple to understand, to establish control inputs and to use, and its instruction manual is thorough, wellorganized and very easy to read. And at $250, it's an excellent choice!
