I purchased a Spectrum DX7s a year ago but the radio has only been used on the bench at this point. Before I start investing in extra receivers I am trying to decide if I should sell it and go with a JR XG8 as I have always used JR in the past and still have a 7202 on 72 MHz that I still use as well.

What are your thoughts as to either of these two radios? Is it worth changing over at this time before I am to heavilt invested in the DX7s?

your not stuck with a dx7s there are other Sprektrum radios available the rx aren't badly priced either

Is JR still better quality?
Or if your already doubting spektrum just go with JR and have peace of mind

I've been using JR since 1980 - so I'm a huge fan of theirs. However, Spektrum have really pushed radio technology forward at a price that will suit most.

If you go with JR, be aware that their technology DMSS is not compatible with DSMX or prior versions. It's all new and unique to JR.

JR have started a new company (JR Americas) for distribution. It seems to me that an all new company will be handling repairs too. That means Horizon Hobby, who are simply wonderful in their support for Spektrum and JR will only be caring for Spektrum - JR would presumably go somewhere else.

The above is my humble opinion based on recent changes. I could be wrong. Regardless, compatibility wise, Spektrum and DSM in some form is number one. I'm sure JR will catch up, but I know that I'm not about to ditch some 20+ receivers to switch to DMSS.

You don't have that problem, so perhaps you just need to look at sales, service and support, and features for a price.

By the way, the new Spektrum DX9 seems to be a winner and much less expensive than the XG14 (or 14XG depending on where you read about it).

I recommed Spektrum all the way. It's owned by Horizon and they have a proven track record for customer service that is second to none!! The new company distributing JR has yet to prove themselves in which direction they will go with customer service. Spektrum is coming out with all the cool electronics for both helis and fixed wing too. Not only is the JR protocol not compitible with anything but themselves, the're not offereing the extensive line that Spektrum offers. Plus, the Spektrum line is compatible with all the Eflite, Hangar 9, and Parkzone BNF planes that are on the market. Like I said before, I'd go with Spektrum all the way, I did!!

I am going to buy an XG14 when they come out. I have watched too many unexplained crashes, spontaneous receiver unbinding, full down elevator, brownouts, etc. from Spektrum - s/w bugs. The DX8 is particularly crap - first Spektrum only TX. And then there is the design feature of Spektrum where you set failsafe at binding. Giant step backwards from PCM which was around in late 80's.

DMSS will have some bugs to work out.

When it comes down to it, your looking at the quality of the Tx, the Rx, the software, and the 2.4ghz technology's used.

IMO....
Tx- JR makes a solid radio, with a good feel, followed by Futaba
Rx - JR and Futaba are on top
Software - ease of use goes to JR, programmability goes to Futaba
2.4Ghz technology - as long as you have two channels that constantly change frequency your good. That rules out DSM2.

Things to consider;
BNF is spectrum technology.
Number of channels needed for your enjoyment.
The size of your hands, some radios are smaller or bigger than others.
Price point.
Telemetry
Compatibility with your FBL system.

Woes
As stated above, I have had binding issues with spectrum stuff. When I was flying DSM2, I was constantly re-binding. I landed once with only one Rx bound.

I currently use the Futaba 8FG, for my Helis and the JR9303 with the DMS2 air module for BNF.

It's getting tough out there in the radio world, good luck.

P.S. my bind and fly is MCPx and the BL version. I anticipate those not landing on the skids 25% of the time. So no worries there.

I have been using my 2 XG 8 about a year now.

All I can say is I'm glade I switched.

The reason I switch was I was getting glitches, problem solved.

Does anyone else besides JR have DMSS compatable recievers yet or is JR the only game in town?

DMSS technology is exclusive to JR.

at this time there are no receivers that are compatible with DMSS.

I have been flying Spectrum since I bought the first DX6 my LHS sold. I have flown everything from micros to helicopters to giant scale airplanes and, a RC Skydiver. I have only experienced a glitch 1 time in seven years. I have owned DX6, DX7, JR9303, DX9. Receivers are half the price of JR or Futaba. I will continue to Fly Spectrum as long as I am able.

By the way I have seen a lot of people blame equipment for pilot error.

I just don't know about that boy.

The DX-9 is where my money would be if I were buying today. I have two DX-8s (for me and grandson) and they are very nice radios. I am also a JR fan from days past and have a the DSM module in my PCM-10, but it just sits on the shelf because the programming of the 10 is just so tedious. The Spektrum software is very easy to use and you should not discount how important that is. JR programming is still in the dark ages as far as I am concerned.

Just curious, could you explain why you think JR radios are in the dark ages for programming?

Programming JR!!
I switched to JR back in the early 90's when it was a Century radio...mostly because they are so easy to program..
Having used both Spektrum and JR, I would have to put them on the same page at least..
I started flying some hi $ scale helis about 2004-5 and have tried to stay up to the latest technology just for safety reasons.. at this point I am all dsmx, but since I try to make all the larger, more crowded events during the season, I want the latest even though I have not had a glitch on dsmx or even the dms2..
Bottom line is what you are comfortable with, and having Horizon staying on to take care of service is a win win for me!!

Thx Stan

Stan,

Good post. The large events would be of my concern when I fly my 5K helis. Not to say that the lastest technology is bullet proof, but for me the less potential the better.

As for glitches, I experienced 2 heli flown a different fields which had intermittent hits and locked up then regained. When I switched over to DMSS, I never had this issue again.

There is nothing wrong with DSMX, its just what your comfortable with.

I have two JR Radios that have Spektrum (DSM2) technology (four is you count my old JR 10X with a Spektrum module, and my DX7, which was made by JR for Spektrum).

This is a very good combination as you get JR quality and the ability to do "Bind-N-Fly" (which I do a lot of-I love foam warbirds and micro helicopters, as well as larger helicopters).

Brown outs are a function of inadequate current capacity to the receiver/servos/FBL unit and are easily dealt with, proactively, though the use of large BEC's with multiple output leads, or large capacity, on board batteries with multiple leads). The issues with Brown outs, historically were the slow recovery time as the receiver scanned through all 80 available frequencies in order to identify the two it was originally on, prior to being able to re-link. Spektrum corrected the slow recovery from a brown-out with "Quick Connect" several years ago, but this seems to be consistently overlooked or forgotten.

I have never had a brown out with Spektrum and have been flying it since about one year after the original DSM, DX6 (DX6-not DX6I) came out.

I have just received my JR XG14 with DMSS, along with several receivers, and will be migrating over to it. It has a very good, solid, ergonomic feel and the programming is very intuitive.

I will continue to use my older JR Transmitters for the Bind-N-Fly aircraft. I expect them to continue working for quite some time (my JR Galaxy from the early 1990's still works fine).
