[RCSE] So, having read the 2.4 Articles in this Month's RCSD, What's your 2.4 opinion?
I really appreciated the information on Advanced Range Testing. While I've had mostly good luck (yes - it really is 'luck') with 72MHz, the expense and horror stories of 2.4 have kept me away. With this article, a realistic analysis process seems possible which would address the reception problems. Now it's just a matter of expense... -Keith RCSE-List facilities provided by Model Airplane News.

[RCSE] So, having read the 2.4 Articles in this Month's RCSD, What's your 2.4 opinion?
I've been on 2.4 since September. No problems. Flew on 2.4 at the Visalia contest and everything worked perfect (JR9303). I plan on flying the F3J world champs next year on 2.4. I guess that means I'm sold on the technology. I think I'll be posting some VHF stuff for sale soon (real cheap). One point does need to be made and that is the receiver installation will impact the range performance. For this reason, it is important to read the instructions and to carefully range check a new installation (and periodically double check it). There is a small glitch counter that records the lost frames of information during a particular flight. Actually, the receiver itself records the performance data and the counter just reads the info. You can improve your receiver installation and see data from not only the main receiver, but the aux receivers as well. I've seen at least one, (slightly problematic) installation that was improved big time by just moving the aux Rx a couple inches to a new location. I've been flying the 2.4 in a Zenith 3.7 It has a CF fuse with a fiberglass nose. I helped the other Joe (Joe Rodriguez) install a 2.4 receiver in his Artemis Light for the Visalia contest. It has a full CF fuse, so we poked the main Rx antanna out each side of the fuse (they stick out about an inch on each side) and mounted the aux Rx behind the flap servo since the wing has a fiberglass skin (not a CF skin). The only CF in the wing is the spar (which could block it from the front, but then the fuse antenna would still pick up the signal). No problems. None. He also flies it in a Zenith. The aux (satellite) receiver is important. It actually does most of the reception work if you can get it away from the rest of the radio. If you're flying a plane with CF, I'd recommend the 9 series receiver with the satellite receiver. You can actually plug in two aux receivers instead of just one. I'll probably do that. Not that I've had any problems, but just as a warm fuzzy. They hardly weigh anything, so why not? Have you ever been to Visalia on a friday with the chaos and everyone shooting each other down? Imagine that not being a problem with 2.4? Imagine contests that no longer need TX impounds, frequency pins or a matrix that takes frequencies into account (and the manpower needed to deal with all that)? 2.4 is here to stay. Start learning about it and talking with those who use it. I think you'll find that it works. Make the switch when you're comfortable or looking for your next radio. Fly it in your beater airplane to gain confidence (if it range checks good, it will work. So, I didn't have any worries about testing it in my primary contest ship). If anyone has any horror stories, post them along with all the details. I think you'll find nearly all the problems to be installation or operator errors. I'm assuming everyone is talking about the JR/Spektrum equipment. There are other manufacturers of 2.4/0.9/non VHF equipment. I haven't tried them, so I can't comment. The only thing I do know about them at the moment is that not all of their stuff works.yet. When picking out your next radio, look at what everyone else is flying.

Re: [RCSE] So, having read the 2.4 Articles in this Month's RCSD, What's your 2.4 opinion?
The Futaba FASST system has two antennas and does not use a second RX. Each antenna has a short piece of coaxial cable on it (very small diameter) that is a few inches long. This makes it much easier to get the antennas out and away from the CF in a fuse, etc. Just wanted to throw that so it was clear that not all systems use a second RX. But regardless, it is important to get the antenna(s) out where the RF can see them!! Bill RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] So, having read the 2.4 Articles in this Month's RCSD, What's your 2.4 opinion?
I think that it is a very well written and informative article about the 2.4 ghz Spektrum system. I would only add two comments that I feel are important. Sherman's article only addresses the JR 921 receiver or the Spektrum 9000 which is the same rx but in a different colored plastic case. The JR 921 or the Spektrum 9000 unlike the other offerings from Spektrum are the only two receivers that offer a true Failsafe. Smart safe only holds the last servo position, whatever that maybe while Failsafe takes the servos to a preset or failsafe position. Personally I see nothing Smart about Smartsafe. I recently lost an AVA that I had been flying on 2.4 ghz. The AVA had been on Spektrum's 2.4 ghz system for several months with no problem. Then one day WHAMO no control at all and it went straight in from about 300 feet. Yes I performed a successful range check prior to flying. I sent everything off to Horizon and they could find no problem. Then I read a post by Don Richmond where he stated that he nearly lost his AVA which was also on 2.4 ghz. After recovering his AVA he noticed that one of the little lights in the satellite receiver was not on. He felt that he had lost his bind on that receiver. I don't know if it is possible but it makes sense to me. Anyway Don rebound the receiver and has not had the problem since. Now, after turning on the power to my new 2.4 ghz powered AVA I check each receiver to make sure that all of the lights are lit. There are two in the JR 921 and Spektrum 9000 and one in the satellite receiver. And thats what I think.

Re: [RCSE] So, having read the 2.4 Articles in this Month's RCSD, What's you...
In response to the Failsafe issue. There are several 2.4 receivers in the JR Horizon Hobby Catalog. They are: 1.AR9000 15 Grams Comes with both Smart Safe and Model Match 2.R921 (JR branded AR9000, I think) Same as above 3.AR7000 14 grams Comes with both Smart Safe and Model Match 4.AR6100e End plugs 4 grams NO satellite receiver No Smart Safe 4a.AR6100 Top plugs 4 grams NO satellite receiver No Smart Safe 5.AR6200 10 grams Smart Safe and Model Match 6.AR6300 2 grams JST connectors and very thin NO satellite receiver No Smart Safe. 7.AR9100 NEW and designed for Giant Scale with a larger power buss See AR9000 for the rest. I will have to do more work on the AR6200. The paper with the receiver discusses both Smart Safe and a preset FailSafe. So I will have to see what is actually there when I do the Blaster 2 Build.

RE: [RCSE] So, having read the 2.4 Articles in this Month's RCSD, What's you...
Sherman, I liked your article and found a lot of valuable information in it. However it is my contention that SmartSafe is nothing like the failsafe that we love so much. As a matter of fact I see nothing smart or safe about it. Here is a direct quote from the Spektrum information manual that comes with the Spektrum 6200: The AR6200 features a SmartSafe failsafe option. Smartsafe is ideal for most types of electric aircraft and is also recommended for most types of gas and glow-powered models. With SmartSafe, when signal is lost the throttle channel only is driven to its preset failsafe position (normally low throttle) while all ofher channels hold last command. As you can see the flap channel on sailplanes or the throttle channel on an electric are the only thing that will come to a true preset failsafe position. Everything else holds its last commanded position. To me this is not failsafe like in my JR 770S. The only reason that I point out the differences in SmartSafe and Failsafe is so that no one mistake one for the other. So if you are buying a new receiver and want Failsafe and not SmartSafe and your model is large enough get the JR921 or the Spektrum 9000. Everything else is SmartSafe. As for model match I think that it is a great idea and will save quite a few planes.

[RCSE] So, having read the 2.4 Articles in this Month's RCSD,
Gordy, You asked for a review of the articles. Having read the articles I felt they were clear and well organized. In the first Sherman focused on what he felt were key advantages of the 2.4 GHz system. Much of the article was either quotes from the manual or the marketing material, which he used to explain those features that Sherman felt were attractive and important. The second article was also clear, but appeared to be intended to be published independent of the first as it repeated some of the same points. From that point I felt it was a little redundant, but not a problem. Sherman showed the manner in which the system was installed and spoke of his experience. He was clear that this installation was in a Supra with the new 2.4 GHz friendly pod. Overall he seemed very happy with the transmitter, the receiver, the way the system worked. It is his intention to continue to share his experiences with the 2.4 GHz system as he uses it in a number of other planes. Based on Sherman's articles, I would be interested in this system for use in my sailplanes.
