Kiwi's XPS test results are up.

[Cherokee Jim]

Hello All,

I got my XPS TattleTale and have been testing it out on the bench and ground testing, no flights yet. Works as advertised sofar, I do my bench testing using a precision Voltage/Current source - Yokogawa 7651.

The unit is nice and small and very lite. After I flight test the Tattle Tale I will get one for each model. It is an investment, I want to know when trouble is developing. Or in the worst case to know the cause of what happened. I am good at detecting pilot error --- tooo much practice!

Happy Flying,
Cherokee Jim Mahoney

Hello guys, I haven't read this entire thread yet. But is there a chance the new Aurora9 will be tested or has it been tested already? Very interested to see what the verdict would be on it.

Neat video. Our adpative frequency hopping mode (released back in 2008) does the same thing except you don't need to turn the transmitter off. Our system is always adding and removing frequencies in real time.

I find it interesting that the people that were really tricked still believe the lies of Spectrum. Dual antenna diversity. They believed the ads simply because it was an ad. They cried and kicked and moaned about how XPS with only a single antenna could not work because 2.4 required 'antenna diversity'.

Now that many other companies are only using one antenna and even Spectrum is shown to be using only one antenna. They will not apologize for being rude and abrasive and wrong.

BTW where is the biggest mouth of all that said he was going to make his own 2.4 system. He even took money for it on his website. I certainly do not see any 2.4 system coming from him. But his baloney sure had all the followers crying hallelujah.

Spherical antenna pattern. They still can't understand that all of the planes we fly can receive from all directions. So if you advertise a spherical antenna pattern that is indeed what we all have. Really dumb to be telling everyone that XPS lied when from day one anyone could prove that XPS has a spherical antenna pattern. Take an XPS equipped plane and rotate it in a spherical pattern and lo and behold the aircraft responds in all positions. So some people, especially W are really, really stupid when anyone can prove time and again that XPS does have a spherical reception pattern.

I guess when no one will listen to you in real life the only way to get attention is to come here and say really, really, really, dumb and ignorant things to get attention. BTW it is not nice to continually insult all the people flying XPS without any problems claiming that they are stupid to fly a system without problems.

The lie was more the "patented, eight element" claim. Of course it receives from all directions, more or less! Have a look here: http://www.flyelectric.ukgateway.net/24logger.htm. When will we see similar graphs from a XPS system, with all it's telemetry features??

[Woketman]

What about all of the folks that had adequate power supplies yet were done in by 1st gen XPS's non-hopping design?? Eh? Did you already forget about that??? Oh no, don't bring up the legendary Boeing test with the secret results!!! HA!

Remember: if JD's lips are moving, historically.... well, we all know what that means!

Ummm the AR6000 rx does have two antenna. That's the only small Spektrum rx without a sat that I even trust a little. I have been testing the Futaba 6 channel "HFC" rx with it's single antenna routed outside the fuse and so far it has been good.

As for people crying foul about XPS, well it's been pretty much the same level of BS on both sides, for and against. I still say if it is working for somebody, they should stick with it. If not, do the basic trouble shooting and if that does not cure it then go FASST or equivalent.

I am no way an expert with electronics or matters of Rf.... but allow me a moment to share my experiance....

I fussed with a 2.4 ghz video system about 10 years ago.... only like 50 or 100 milliwatts.... and one thing I observed... when the Tx antenna and the Rx antenna were both oriented the same way, (both pointing up, or to the east or whatever).. the range was about 1300 feet.....
If I turned one antenna 90 degrees with respect to the other antenna, the range was closer to 350 feet..... this was obvious as the quality of the picture degraded.....
I believe.... the reason for this is a sensitivity to polarization... something about the "Electric Field" and the "Magnetic" field being 90 degrees to each other... (Rf is an "Electro-Magnetic field right?)

So having two receiving antennas, at 90 degrees to each other,with the decision making ability of the Rx to take the strongest signal, (I believe), is the way to cope with the polarized sensitivity of the 2.4 Ghz spectrum....

that is my observation anyway... maybe there are some Rf Gawds who can correct me if I am wrong.....

One issue with any adaptive system is the difference in the RF environment when the receiver is maybe 1000 feet away from the transmitter instead of right next to it, like when they link up and select frequencies. That's one reason why pure frequency hoppers usually just hop around the entire band regardless of what the receive environment at any particular time or place (distance) is. Also, any system that relies on 2-way communication between the transmitter and receiver has to be especially robust, because the link could go down in one direction but not the other at some time. I'm not saying that they can't be made to work well, but they're needlessly complex.

What he said. JD has lied in the past, so why should a consumer believe him now?

[Woketman]

Exactly!!!

But maybe if he were to reveal the super double secret Boeing data (that does not really exist), maybe we could trust him..... NAH!!!!! Just kidding!

He has lost all credibility with the majority of those who have followed this saga. Only the fan-boys believe him now!

[skubacb]

You're always so funny. LOL You never add anything and try to discredit by repetition on what has already been proven true. Let me see. The Boeing people confirmed what the XBee people have out there in their data. Have you looked at the data? And you, if you can pry yourself away from the computer can go and confirm the same thing yourself. So the only one that is not credible about this is ...... Oh just take a guess the name here is W...... Just so funny and makes me laugh.

You're pretty funny too

[Woketman]

OK, let's see the imaginary Boeing data then, eh???

Yeah, that's what I thought...... nothing. All a bunch of BS, JD's signature!!!
