Independent tests prove lack of frequency hopping with XPS

[Kiwi]

Ed,

I have and will remain neutral on the debate of XPS being good or bad but your post would make me one very annoyed pilot if I had already lost a model to XPS in the first place.

The reason I say that is everyone I know who purchased XPS done so thinking they were getting the channel hopping, channel clutter avoidance etc etc in the original model.

To say the next release of firmware will provide the user with the funtions he already thought he owned just adds insult to injury. Plus I suppose the thousands of current XPS owners will get the firmware upgrade for free given that they only got half of what they paid for in the first place.

I have highlighted the statement that I think will unleash the lions if this proves to be a factual statement.

an update that the next firmware update will include the ability to change channels when interference makes the current channel unusable. I look forward to having this additional functionality.

If you already own XPS I thought you already had that functionality.

What I like is that while loose wires being close to the antenna are being blamed as a probably cause for loss of signal and to be sure and wire tie them back, he posts a picture of his jet with this.... We asked for end pins along time ago but...

I've been forced to the shoulder of the road by a car while riding my bike and hit a telephone pole at about 50 MPH give or take. So yeah, I feel and have been told how lucky a "punk" I am. I have however seen more serious injury from small planes than large. Mostly due to "dumb thumbs" or a careless operator. I'm sure though that anytime someone attempts a "hemple" will have everyone looking for shelter. Except for me I guess, it's like a train wreck, seemingly happens in slow motion and you just can't look away. Curious though. Ever run two Rx in a say six foot plane ? Why not ? I'm also suprised that you refer to "granpa" in the pit's next to you. At 50 if you are not a grandpa you are missing out big time. I expect in about 8-10 years I'll be a "Great Grand pa". Sorry everyone. I digress. Name calling seems beneath this site and I appologize for even commenting on it.

uh . . . zoomer. . . you misinterpreted my Clint Eastwood quotation. "well, punk, do you feel lucky" is a line from Dirty Harry, and is a generic "I dare you" line for those familiar with the quotation. Nothing more or less.

As for the JR receiver. . I really don't need another one. Have more than enough at the moment, thanks anyway. But, I'd REALLY like it if Horizon hurries up sending me my Spektrum TX module back in perfect running order. 4 flights and about 2 hours total "On" time and it just died when I turned it on at the field. A rather auspicious way to start off with 2.4 if you ask me. . . .

The carjacker who tried to get ME lost his gun, got shot with it, ran away, AND got his butt severely beaten in the process. . .

I got the pole beat. . dead on into the brick wall of a house at 35mph, no helmet. . but I DID miss the Cadillac by swerving. . which brought the house into the picture. . .
Then there's the 23mm stuff that chewed up the chopper I was in, all within about 1 foot of my body and head. . .

And I once grabbed the wrong tool while blade tracking the 30 watt output of an ARC-52 UHF radio. . and sat there quivering for 10 seconds before a circuit breaker popped and the silly thing let me go . . .the Corpsman said I'd be fine. . . . but I did lose a fair amount of bone marrow in my right hand and arm.

Then there's the time the APX-72 on the test bench was transmitting at 1000 watts on 1.093 ghz, with no antenna cable, about a foot from my groin. . . which kind of explains the lack of grand kids I suppose. . .

Life is an adventure. . .

MPX IPD is as bullet proof as it gets on 72, in my experience. Perhaps a Weatronics type set-up is better, but that is high $$$.

No one has ever stated that PPM was "crap". . only that it IS more interference prone, glitches badly sometimes, and I've actually seen people fly with these glitches, because they have grown so used to them that it's nothing worth worrying about. . to THEM. . the rest of us go into hiding when these Yahoos fire up their planes and take to the air. . . and wisely so, IMHO.

As for IPD, since it has failsafe, it's literally PCM, just not encrypted in the same manner. It does have some nice features, and I once considered trying it, but I stayed with PCM instead.

Ya mean JD is FINALLY going to make XPS hop????

Kiwi should still test the new firmware updated receivers. . jsut to make sure. I BET, in a saturated channel, where TX and RX cannot hear eachother, they will still stay locked out after a few failed attempts to re=establish link.

Actually what was stated was the next firmware update has it hop when it sees the massive interfernece like a 2.4 video camera (something XPS states would swamp the entire band).

This is not an upgrade of the current way it hops for potential interference on its specific freq.


It will be interesting if the upgrade solves the problems people appear to be having or does nothing.

[buttface]

If JD could make finaly make it hop I would still never buy another one.He is shure to go out of buisness this year.

[sweetpea]

I doubt that will happen.

I don't want to see it happen.....competition keeps the prices low. Take out your competitors and the prices will rise.

[chewy]

There are lots of competitors coming from China... Assan, Corona, IMax etc

I would not consider XPS as a competitive threat and I am sher the other companies don't ether.It's more of a failure than competition. XPS is the laughing stock of the market.

[sweetpea]

XPS may not be your first choice anymore buttface or many others but there are still lots of folks out there that prefer it......if for nothing else than the lower price.

I would say the precentage of flyers that go to online forums is quite small compared to those that actually fly and that is where any of the questions about hopping or not are at.

I just may go with the "end pins" for a glider I have.......

Looks like it would be easy enough to do. Maybe not perfect with a factory box, but oh well.

Being cheap puts you in the ground.XPS can't hold a candle to the other 2.4 brand name equipment.
Every time I buy some thing generic it breaks.It reminds me of a plastic Dollar Store product.I am just glad I didn't loose one of my 40%ers to it.I give everything the benefit of the doubt.And I can scratch XPS off of my list forever now along with that green plastic slingshot from the Dollar Store that broke on the second shot when I was a kid.
Hey If you are looking for a good "bargain" on XPS stuff you can get the modules and receivers out of a .25 cent bubble gum machine now at Wallmart ,it next to the "Bubba Teeth" and "lick-n-stick tattoos", Items that every one likes to get a bargain on!
Hell you could get the XPS , sum Bubba teeth , and some lick-n-stick tattoos when you fly and look like a BILLY BAD ASS when your ship dose a nose dive!

Hey Sweetpee! I bet they got sum "XPS FOREVER" tats in that machine at Wallyworld...

Buttface, Come on now.Your remarks are starting to sound like they are coming from your avitar...in other words your trying to be funny sounding as well as funny looking. Only the looking part is working. We all know you don't like XPS, you keep saying it. Now why don't you pick another subject or person to to trash. Use me if you want to. But stop on XPS you sound like a broken record.
