JR 2720 PCM SET SYNTHESISED

JR X-2720 Overview

If you’re ready to move up to a 7-Channel radio, this is the one you’ve been waiting for. With its breakthrough features along with the unmistakable feel of JR quality, the JR X-2720 is everything a serious sport flyer dreams of.

And speaking of breakthrough features, let’s start with one you’ll really appreciate.

NO MORE EXTRA CRYSTALS TO CHANGE CHANNELS

Since we have so many frequencies to work with, it’s rare to find several other flyers using your channel. But when it does happen, all you can do is wait your turn or plug in another set of crystals.

Well, the JR X-2720 ends that problem right off the bat. You’ll just check for the least-used channels at your field, program one into your transmitter, touch your RS77S ScanSelect receiver’s “scan” button, bring your transmitter close and it’ll tune to your programmed channel automatically.

PCM PRECISION ISN’T JUST FOR THE PROS ANYMORE

You’ve probably noticed that competition flyers always fly with PCM modulation, and there are good reasons why they do. Modern PCM receivers offer unmatched accuracy of control plus an additional layer of resistance to interference.

And as an advanced sport flyer, we figured you deserved the same advantage. This is the reason we equipped your JR X-2720 with the RS77S ScanSelect PCM receiver.
And by the way. The JR X-2720 is compatible with all previous JR receivers – PCM and FM – so it won’t make your existing equipment obsolete.

SUPERB SERVOS, 20-MODEL MEMORY AND MORE

Let’s start with the “and more” part. As you can see in the large photo of the JR X-2720 transmitter, its display is unlike anything in its class – more detailed and independent of fixed elements. Which means it makes programming easier to comprehend and even easier to execute.

Next, the 2720’s servos – the new zero deadband, 5.2kg/cm of torque, DS589 digitals – not only out-perform those of competing systems, and they feature special ultra-tough Carbonite resin gears for long-lasting, precise performance.

And finally, it has the entire programmable features airplane and heli enthusiasts need to get the best out of their models, plus it’s an absolutely unbeatable value.
So don’t leave your JR X-2720 waiting with us. After all, when there’s the 2720, why would you even think of settling for anything less?
