JR PROPO DSX7 2.4Ghz 7ch Transmitter & RD721 Receiver Combo with 3 x ES539 Servos + Tx Battery New Version 3
DSM2 system for Helicopters and Airplanes of Any Size. Fully Compatible with Spektrum Radio System
With the DSX7 you’ll be able to fly anything from micro electric helis, to big gas-powered planes without regard to frequencies and free from fear of interference. Never again will you have to ask, “What channel are you on” Never again will your flying experience be interrupted by model-generated RF noise, interference from commercial broadcast towers, or anyone on another RC system.
The big difference with DSM2 is that it not only flies any size model with absolute precision and complete freedom from interference, but it also processes its signal faster than any high-end PCM system.
DSM2 — Security and Speed:
Unlike most first-of-its-kind innovations, DSM2™ is not an unproven concept. It is based on the same Spektrum 2.4GHz DSM (Digital Spectrum Modulation) that RC car racers, as well as micro electric and park flyer modelers, have been enjoying for at least two years.
Like DSM, DSM2 provides an impenetrable radio link that’s immune to every known type of RC interference. Because it operates at 1024-bit resolution, it provides the kind of locked-in response that will have pilots feeling more connected to their models than ever before.
RD721 Dual Receiver — Spectacular Signal Clarity:
The RD721 dual receiver that comes with the DSX7 is key to the system’s incredibly robust RF link. Comprised of a compact main receiver that is linked to an even smaller satellite receiver by a 6” lead, the RD721 acts as a pair of extremely sharp RF “eyes” that each take in a slightly different view of the signal environment. Information from both receivers is then processed by patent pending Spektrum software that takes information from each receiver and combines it to form the most vivid “picture” of an RF signal than has ever been possible before. What’s more, there are no long antennas to accommodate. The RD721’s short 3” antennas don’t require any external exposure, so installation is an absolute breeze.
Servo Sync and Model Match — Extra Safety and Precision:
DSM2 and the RD721 aren’t the DSX7’s only marvels. JR engineers have come up with two more patent pending innovations that you’ll wonder how you ever lived without—Model Match™ and Servo Sync™. Servo Sync is an ingenious new feature that actually re sequences the bits of data the DSX7 transmits based on the type of mixing you select. So, if you have a dual elevator on your big Extra or a 3-servo CCPM setup on your heli, Servo Sync will see to it that those servos working together receive their impulses together. The result is more synchronized servo movement that translates into an undeniable, locked-in feel when you fly. Model Match puts an end to the “wrong model” syndrome. Almost everyone who flies RC has at one time or another crashed because of neglecting to verify the model name on the transmitter display during preflight check. A unique code is embedded in the DSX7’s signal so that, if the wrong model’s name is on the screen, the model’s controls simply won’t respond.
