Problems!! 14MZ 2.4 R6014FS

[Kiwi]

Ah you mean those nice little Caterpillar temp recorders we use to tell a customer he just flunked his warranty because he cooked his engine and it ain't my fault sorry Sir!!!

The sky was falling when the zero id problem was first discovered and with a little common sense it was easy to tell if your transmitter was working properly. I been wondering what it would take to get the temp of my receiver up to 160 F without doing something out of the ordinary. Again I think a little common sense can eliminate this problem.

The other thought I have is why would I overheat my receiver to see if I could make it fail and risk damaging the receiver because of overheating. I don't think anyone would argue that heat will eventually damage or destroy electronics and I'm willing to beleve it will fail at 160 F or 55 C, which I think is about 132F.

I love how quite an engine is on pipes or cannisters and I have not got a Comp-arf because it seems to me like you are asking for problems with such a huge heat source in the some compartment as all your electronics.

As mentioned before: Other RC equipment manufacturers give you a temperature range, and you will have a hard time finding one which will give you more than +55°C (= 131°F).

Can i draw on peoples knowledge here for the best heat stickers that would fit on receiver and record the highest temps it's ever got too, and need to be pulled off and thrown away to be reset. Ones that people have used maybe or know that are good. Please provide links to online purchase places like this which i don't think is one that hold the highest temps it changes back when cooled. http://www.endpcnoise.com/cgi-bin/e/...e_temp_sticker

Those be the ones.

Have to catch up with you some time next week to see if we can come up with a way to correct CAT deficiencies

I just returned from this weekend's IMAC here in Southern California. I did not do an actual count, but it looked to me, that for the first time 2.4 radios were the majority. I believe all but two of the 2.4 users were flying JR/Spektrum. There was only one frequency conflict among those still on 72. They didn't even bother with a radio impound, and just introduced the two with conflicting frequencies, and told them to work it out. This is a big change from just a year ago when I attended my first IMAC. At that event, radio impound was a very serious thing, and still two planes were lost due to people accidentally shooting down a fellow competitor. 2.4 is having a big impact out here.

The weather was nice, warm, I'm guessing low 80 degrees, but full sun. The two people that were flying Futaba 2.4 were both wearing their Team Futaba "T" shirts, and since I have been following this thread, I took the time to speak to them about this issue.

The first one said that he had spoken to Futaba about the issue, and yes, they are aware of it. He said he was not concerned at this point, because he had set up his plane "properly". He had mounted his receiver low in the fuse, had a foam insulated canopy floor, "as all planes should", and didn't expect his RX to heat up with this setup. Still, he kept his canopy covered with a large towel, and took care to position his plane in the shade. I asked him about this, and he said he did this because he was worried about the canopy deforming in the sun, more than the receiver getting hot. He is a straight forward guy, and I believe him on this.

The second pilot, was not entered in the IMAC event, he came out in the late afternoon to fly the freestyle. His RX was mounted under the canopy, without a cockpit floor. He took no special precautions to keep his plane cool. He said he also was aware of the issue, but not concerned. He is a techie, and in his opinion, all electronics have some sort of potential heat issues. He did say, that he was planning on ventilating the RX cases on his receivers if they starting getting warm.

The weekend went well, and no one, running any brand, or type of radio, had any problems with them. Including Futaba 2.4 pilots. We are lucky to be flying with such reliable equipment these days. However, at least at a perception level, Futaba does have a problem. A third flyer at the field, who I know to be a big Futaba fan, has had two new planes professionally built for this season. I asked him why he was still flying his old plane at the contest. He said they were ready to go, but he didn't want to buy any more 72 receivers, and wanted to fly the new planes on Futaba 2.4. He said he has been watching others, and reading threads about the Futaba 2.4. With all of the "apparent issues" Futaba is having, he was not comfortable installing Futaba 2.4 in his very expensive new planes. He says the planes will be at the next event, because he was tired of waiting on Futaba to "get it right", and has ordered a JR 2.4 system to install in his planes next week.

I decided to post this report, not to start a brand war, but because I find the 2.4 technology very interesting from both a technology, and business perspective. I have been in the hobby only a couple of years. But when I started, the only radios I saw were 72 band. A short two years later, 2.4 is already the majority among the people I fly with. Not only that, most are now flying a JR/Spektrum brand radio because of the lead they had to market with this technology. In a way I was an early adapter of 2.4, buying an original DX-6 to fly my small electrics with. Still being conservative by nature, I flew PCM on my bigger planes. I have been slowly converting my big planes over to my x9303 as we all learned things about the system, and I gained confidence. This seems to have been a wise choice as JR, like Futaba, had issues that were not fully understood in their early releases. All of my planes have been converted, except my 40% IMAC plane. Yes, I was one of the minority still on 72 at this weekend's contest. I think I will go ahead and do the conversion before the next event.

I really like Futaba's implementation of 2.4 from a tech point of view. However, JR/Spektrum has such a big lead in marketing, and user acceptance, that Futaba will have to be very proactive in their handling of issues such as the heat problems being discussed in this thread. I hope they will do that.

In Europe, with a 100mW max. EIRP peak power output, we have a different situation. Futaba FASST achieves twice the range.

[rcflyer]

What's the EIRP peak power output in the USA? Thanks

[1bwana1]

Jurgen,
That is interesting. Is the JR/Spektrum system having problems with range in Europe? Is the acceptance of 2.4 not as high there as it is here?

I think the lead that you observe with JR is a regional phenomenon...
