No the real head scratcher is why does Spektrum get more non-users chasing people around through threads that don't relate to their radio system only to say or vote how bad it is?


While it is entertaining to read i just dont understand the mentality it takes to do so.

Defend an investment?
I guess some would do that -
how can a few have repetitive problems with so many satisfied users to show them how to use their equipment.
The answer is that most users learn how to use their stuff correctly.
You can't cut corners with power or setups.- it just doesn't work..
Those who refuse to learn - are just fooling themselves.

6 + 50 + 10 + 8 is much less than 100.

In 72 MHz, the spacing and other technical conditions allowed for interference when there were transmitters of particular frequencies on at the same time. As a result, we in the impound had to make sure that we didn't allow simultaneous operation of transmitters on the same frequency or in combinations that could create those interferences.

With the advent of Spektrum and the wholesale adoption of our technology, and later by other brands coming along, most contests went to a 2.4gHz-only policy. Users on the old bands either had to leave their radios home, or manage their radios among themselves. (Staffing the impound was never a fun chore when hosting an event).

Now, armed with these facts, please explain how users at Joe Nall would have have the ability to launch 100 planes simultaneously as was demonstrated by the video.

Thats a bit rich since you're not the only technology using DSSS in the 2.4Ghz band nor are you the first. The first in RC perhaps but not the first DSSS and certainly not the firs user of the 2.4 band.

Hm, I don't think Andy claimed either, only, by inference, that Spektrum is a fine product.

I certainly have enjoyed my Spektrum products.

I'm sorry, Tim, but I don't understand why you should think anybody is making those claims. It sure isn't in this thread. Are you reading another thread somewhere with misinformation and trying to draw it into this discussion?

I would still like to hear your explanation for how it would have been possible to successfully fly 100 airplanes simultaneously on only 74 frequencies with the standard AM/FM/PCM technology of the day.

The answer is that Spektrum lacks any kind of significant quality control - from hardware to software. It treats its users as beta testers.

It is clear that you think every failure is a result of a faulty power system - even in those cases where people have switched radio brands only to have their mystery problems solved. However, it seems that even Spektrum recognizes that they have signal problems as evidenced by the numerous "kludgy" solutions they have thrown at the problem (e.g. more satellites, duel TX antennas).

How many Toyota owners are still driving Toyota's after the recall of 7.4 million cars this year and 4.2 million cars last year, head-scratchers are everywhere don't try to figure them out if they don't affect you.

There is no need to scratch your head. There are many of us who have not had problems and not had to send our Spectrum radios back. They have proven to be as reliable as any other brand we have used.

I have used many different radios.

Scratch your head if you must, but I do not see Spektrum to be the problem.

"mystery problems ?
Until you resolve that the actual problem was the rx---- how can you logically deduce that the receive was the culprit.
Leaps of illogic just don't proove a thing . But it is obvious that some guys just like to keep a tired thread alive ---
facts which put this all to rest , are no fun.
The public including model crashers -are willing to believe anything -especially stuff they don't comprehend -
Look at the Toyota floormat thing - --people actually claimed they could not stop the car or shut down the engine --and others actually accepted this as a possibility!!

I just have to jump in here… I own three Toyota Prius’ - 2007(son), 2008(wife), and 2010(me). Very fine automobiles. Zero problems and work as advertised. I’ve seen lots of these cars used as taxi cabs in NY and Vegas. I’m thinking about getting a Prius V before the end of the year.

I started RC in 1974 with a HeathKit and then Futaba for many years. I was away from the hobby for ten years and came back in 2005. Bought a Spektrum DX7 (DSM2) and flew micros, 450 helis, park fliers, scale, and 3 meter sailplanes. Two years ago I sold the DX7 and bought a DX8. I love this radio. I have a mix of DSM2 and DSMX receivers including HobbyKing Orange and Chinese Spek knockoffs. I’ve had 3 meter sailplanes to 3200’ elevation with zero antenna frames lost. Nice reassuring feature to be able to quantify the RF reception, Rx minimum voltage, and LiPo voltage for every flight. Best $400 hobby dollars I ever spent.

Well, if the only component that changes is the rx, and results in resolving the problem, it is at least reasonable to conclude (if not 100% conclusive) that the rx was the culprit.

The fact is, Spektrum is a less reliable brand - even if you discount all the reports of lockouts. Their hardware/software has been plagued with problems.

I'm very concerned about the trend in new cars to completely eliminate mechanical linkage between the shift control and the transmission, having it all electrically controlled through the computer. Add to this, the push button start/stop logic also through the computer and you have a recipe for disaster.
My 2005 Subaru has throttle by wire, but a direct linkage allows you to go to neutral even if the pedal is floored (I've tried it, and the rev limiter worked very nicely) and a traditional key switch that allows you to kill the the engine in drive, but not allow the steering wheel to lock under any circumstances is much safer in my book.
