Spektrum to Futaba

[Mikej]

Your fault not the tx.
Did you do your preflight checks? Thought not

remember be SMART

S - Switch on
M - Model Memory / Battery Monitor
A - Antenna correctly position or extended
R - Rates correctly set
T - Trims

I'm not arguing for one moment that it wasn't my mistake that I crashed my heli, but saying that yo don't need some thing that helps safety because we shouldn't need it is like saying we sholdn't have seat belts or airbags in cars becase we sholdn't need them - let's be honest we don't need RC helis. But personally I want model match and if Futaba doesn't have it, I used to have a Futaba Tx when I started and as well as lacking model match, it didn't have sub-trims either and at the time their smallest Rx was massive.

I'm not saying that a pre-flight check isn't a really good idea, however some of us forget things occasionally and MM wil protect us.

... but saying that yo don't need some thing that helps safety because we shouldn't need it is like saying we sholdn't have seat belts or airbags in cars becase we sholdn't need them ...

Try, if you can, to imagine a world in which one car company had patented seat-belts and air-bags in a way that prevented all other car companies from having them.

Even if that car company produced vehicles that broke down more often than others or lacked features the others had, you'd still find people claiming that it didn't matter, because they had air-bags and seat-belts.

Some less well informed might even start criticizing the other companies for not fitting air-bags and seat-belts not realizing that it was the actions of the company that patented them which prevented others from having those features.

At some point you have to make a choice, put up with other potentially bigger problems just so you have a crutch to lean on which covers for a basic pilot error, or take responsibility for doing things right and open up the rest of the world of choices that exists out there once you look beyond Spektrum as the only solution ...

I think from memory Tim I can say we had 3 crashes at least caused by the radio. I have heard many more at the club but think it was not a genuine radio fault

Who knows and my reason for looking to switch is as I said before, down the DSM2 side of it not the actual radio although I dont personally like them, preferring JR to Spektrum I have had to look seriously at the switch. But Futaba radios are no where near perfect, imo the quality of this 14SG I have here is not as good as the DSX11.


We will always get the cross bitching but it is what it is as we all know.

If JR/Horizon have an answer to the puzzling question as to why the system should significantly nullify the benefits of a dual-channel operation by allocating channels so closely spaced, I'd like to hear (and share with readers) that explanation.

A very informative article.

Why the "holier than thou" attitude ??

I asked if a particular feature was available and all I get is smart-arse answers, a simple "no it has been copyrighted by Spektrum" answer would have done, but I have to put up with posts telling me what an idiot I am.

I'm going flying ...

Unfortunately you made a comparison (simile) between two things that are not similar (IMO). We all know we wear seat belts to save us from the other idiot that crashes into us.

As Mark has written you want to defend a product that seems to have a bigger problem than protecting you from flying a model.

It might want to protect you full stop and not allow you to fly at all! lol.

There are ways of protecting yourself against using the wrong model. There is a cheap addon called modelmatch. It remembers the correct settings on each channel and sounds an alarm if it is wrong. I think Multiplex now have a system built in that guards against using the wrong model memory.

[Andy from Sandy]

wrong model choice warning system for Futaba, Hitec etc.

Here is the thread to go along with the video:

Two Futaba 10CHG 2.4 FASST have full control on FrSky TFR6 7ch 2.4Ghz Receiver FASST - RC Groups

If as suggested there, the FrSky receivers are not using the full GUID that would seem to be an excellent reason to stick with the real thing.

Exposed: A vulnerability in JR/Spektrum's DSM2

The limits of DSM2 have been known for some time. Look at the date on the article. This is one of the reasons they had to come up with DSM-J for Japan (they wouldn't allow DSM2), and why Spektrum have DSMX to replace it. DSMX is frequency hopping like FASST, but unlike FASST each radio has a unique hopping pattern tied to its GUID number.

The same guy (Bruce Simpson) now says that DSMX and JR's DMSS are the two systems most resilient to noise on the 2.4 band. Then again, they should be. They're the latest technology.

Fly what you like. If you don't trust your radio system, change it to one you do trust.

Not quite - the analogy that I used was intended to to suggest that lots of people don't believe that they need seats belts as they are safe drivers, but serious injuries dropped dramatically when they were introduced, ditto for air-bags, i.e. something that people don't think that they need that is very beneficial.

I didn't set out to fuel the flames of the apparent Spektrum versus Futaba war - I was simply interested to know if the Futaba system included what I personally (but wrongly it seems) deem to be an important safety feature.

Incidentally I didn't suggest that the SMART acronym wasn't a very sensible safety check - in fact I have now updated mine as follows ...

S - Switch on
M - Model Memory / Battery Monitor
A - Antenna correctly position or extended
R - Rates correctly set
T - Trims

A - Always
R - Reject
S - Spektrum
E - Equipment

Cheers,
Mike

Just to throw out a thought on this. If there are deficiencies in the Spektrum/JR system where they would show up is on fixed-wing because they are generally flying farther away from the TX and thus potentially more vulnerable to interferance. If those guys don't have planes dropping out of the sky then I suggest at least some percentage of these failures on helis are caused by something other than interferance (vibration, RX power, improper mounting of satellites, etc).

I also wouldn't take VBar logs as some kind of holy guide to how to live your life because all kinds of crazy stuff gets spewed out in VBar logs. (Obviously if the logs agree with visible evidence, like a motor cutting out or obvious loss of control etc. then it's a different matter but just VBar logs alone without any other signs of trouble.... I don't know how much emphasis I'd put on that.

If I saw evidence of a real danger I would totally switch (assuming it can also be proven that the Futaba system would not be subject to the same issues).

Ok, so DEFO worth sticking with Futaba rx's then!!!
