Spektrum/JR DSM2 test (Part 2)

This is part two of the Spectrum/JR DSM 2.4GHz RC system review.

Please read the article at: http://www.rcmodelreviews.com/dsm2flaw.shtml for some important information uncovered during the testing process.

Reboot times are very good, even if the reboot voltage is a little high and although it's not perfect, the Spektrum system has provided many model fliers with a reliable RC system for several years now, and that has to count for something.

However, the system is starting to show its age so the question will be: How does Spektrum/JR improve the system without compromising backwards compatibility?

It's not the "best" system from a purely technical perspective but at least it's mature and has great support.

If you're a Spektrum user, what do you think of your system?

The only way to be safe is to have two receivers. That way if one goes bad, you still have a good one. I have read this, but I do not know how to hook it up in any of my planes. Any comments on that? I use Spektrum Receivers (AR9100) and a JR 9503 transmitter, and mostly I'm concerned about losing my giant scale planes to a bad RX.

It would be nice to know the range of the spektum RX and TX as the dx8 2000ft DX7 3500 how come such a large difference ???? be nice to compare

Hi there, you mention doing a comparisom of the various 2.4ghz systems, yet I cant find it. Have you done that one?

Keep up the great work, great channel!

@kiwibob72 Unless you're flying electric with a 2S lipo for the motor then a much better setup is a 2S LiFePO4 (A123) pack for your receiver and servos. Apart from tail-rotor servos (and some gyros), almost all servos are happy with the 6.6V of an A123 pack so no regulator is required and they're a *very* safe/rugged chemistry compared to lipos.

@xjet I guess like any system and or chain ..... things are only ever as good as your weakest link!!

Put a weak link in that just happens to be the power behind the entire system, and your asking for trouble I guess.

I'm just waiting till someone comes up with GOOD and relatively cost effective 7.4v capable servos for my heli and plane, then it'll be 2s Lipo with no regulator (and my DSM2 system) - nothing like overkill I guess!! ;)

@kiwibob72 Interesting you should mention 4-cell packs. A guy turned up at our club last week with a "brand new" Spektrum DX8. It came with a "brand new" 4-cell receiver pack boldly labeled with the "Spektrum" branding. What the?
