How much in $$$?

Thanks.

The PowerJack 6014 unit is $100 delivered to your door. Eur to USD is killing me right now.

If I recall this wasn't a JR issue but a Spektrum module issue. I believe I saw the document that said not to run over 11v to the Spektrum module.

We atteneded the Sun Valley Jet event over the weekend, and there were several people (including Woody) flying XPS 2.4GHz systems in their jets. As usual, no problems when people power their setups correctly.

Who were the several people? (besides Woody and you)

Jim
Is there an upgrade available for the older units?

I used the Extreme power systems 2.4 as it was the first to offer modules & Rx's. I had lost a couple of jets on 35Mhz. I fitted it to my Avonds F15. For many flights there were no issues. As more people started to switch over to 2.4, I started to get the odd lock out lasting a split second. The lockouts became more frequent, so I ditched the system & bought a Spectrum module & Rx's. I have had no problems since.

XPS are now focusing on EDF motors....

Apparently this FEJ electric powered F-14 is powered by their product .....

Jim, you must have forgotten to answer this question?!!!? Who were the several people? (besides Woody and you)????

I've been using XPS since they came out and never have had a problem. I do use direct lipo as power source and now with the updated version I believe now we have proven frequency hopping capability. Just as XPS has lost planes I have seen the first Futabas heat up and planes lost. I believe no single manufacturer is perfect but now most of them if not all have resolved their gripes...
I am an XPS believer, I have it on a 100cc Composite Edge converted to electric with a Hacker A150-8 on 14S pulling close to 200A, I cannot think of a system more unfriendly to receivers...
Just my 2 cents

I used XPS V3 for 5 days before moving to Weatronic.

The first 4 days were fine, no trouble, the 5th day I had a lock out after take off and resulting total loss.
This occured also 1 time in the workshop, and power cycling was the only way to reset it. Not easy while in flight !

My 1 cent !

Homero,

Do you only fly at your local field or do you fly at meets or events outside your local area and state? I'd like to invite you to my field and see how you make out.

I was there flying my Formost 150 EDf on XPS. Been using it for two years with out a hitch.

There is no doubt that the XPS system when it first came out had serious problems, some people got the system to work, but they are in the minority, hence Graupner recalling the IFS system and refunding monies, companies like Grupner do not do this usually they issue a credit note or upgrade the system the unusual step of refunding indicates their belife that the system was not viable and contraveaned the strict "Customer use Regulations" in Germany.

The new system that does have the capability of hopping between channels I am sure is a much better system, would I buy it, NO, I do not like being used as a Development Engineer with a system that could have cost me an airframe, once bitten twice shy, in fact I now will not buy anything Graupner as they argued the case with me until others sent theirs back, I think it was the various threads and Forums that I sent links to them for that finally convinced them.

True, the initial dishonesty that XPS displayed turned off many a potential customer. No matter what some of the XPS supporters say about the original system, those who have followed this closely know there were BIG issues.

It may now be a viable system, but JD urinated up-stream far too much to be trusted now. If you have any sense, avoid XPS like the plague. Especially with the solid performance of JR/Futaba/Weatronics/Jeti 2.4 systems, why in the world would anyone with a valuable model even consider taking a chance??? Sure, some will say "I know this guy that had a JR go in and this guy that had a Futaba go in". Of course, feces happens. But that in no way implies you should trust XPS!

Just don't do it.

Ditto that Wocketman!

Hi George, I mostly fly local and do fly a lot in Mexico as I live most of the time over here. It would be quite difficult to transport my large electric over to Afghanistan, but with my current system I do feel comfortable. I am not supporting in any way the way it came out in the beginning, fortunately for me, in the fields I flew they took too much time to do the change so 2.4 wasn't flooded at all, I don't know if this contributed to my success... I do not know Jim Drew and his obscure past or doings, but service from him/them has been just as any other company would be.

Truth be told, I do like to experiment on new things so I jumped right in a couple of years ago, recently, I have been tempted by all these negative comments on the forums to change, but the fact is that I have not lost a single plane and I don't think I will loose one with the new version and running direct lipos on my planes (voltage seems to be important to the XPS system).

The environment I fly in is criss crossed with high power transmision and power lines, the UK has very crowded airwaves and therefore is a faily harsh environment for any system in a built up area, we fly on an estuary that has communication masts on either side of it, IFS /XPS just would not work on my site, the lock out where consistant and total, ordianary PPM has glitches, PCM seems to be reliable, but all 2.4Ghz except IFS seems to work OK, I have not tried the new system from Graupner nor intend too, as I have said before once bitten twice shy.

Mike

Homero,

Thanks for your honest reply. I only work in Afghanistan, I was talking about flying in Va. Beach. [8D]

It just seems the system works good in only a few places and if you happen to be in one of those places; all is well. My problem is that I travel and fly at many different places and can't trust the system to work at all of them without thoroughly testing at each location. It didn't work at my home field (NALF Fentress), so I lost complete confidence in it. It be interesting to see how the new systems acts, but I won't be trying this time.

Sounds like it is working well for you and hopefully continue to do so. Good luck and thanks again.

George

Thanks George!! I wish you happy flights too!!

Mike totally true, unfortunately for JD and XPS, once bitten twice shy!! I have read many many posts like yours and it seems when it first came out it wasn't tested as it should have... Now XPS has to pay the price and will have to clean up their act or it may be their demise.

Presently XPS has the idea of getting a new system which will transmit in the actual 2.4Ghz but will have a secondary or dual system on the 900 Mhz bandwidth lets see how that goes and when it goes... People, including myself, have been asking about their 12ch receivers with no luck on release dates, he says he will release them jointly with their 16ch ones .

But well, he is trying to keep up and that by itself is outstanding given all the problems he had to face at the beginning.

Maidened another new jet on 2.4. Perfect flight. I have several flights on it now in the last couple of weeks....



On FASST!!!

The problems that he faced he made for himself, he brought an item to the market that clearly did not do what it said in the advertising blurb, it was supposed to hop to a different frequency withing the 2.4Ghz band if it detected interference, it was proved it did not work, hop or reject interference, IMO he does not deserve to have my buisness or anyone elses for that matter, I do not like being lied to in any type of advertisment especially in a circustance that could cost me many thousands of my hard earned cash, my advise to all is not to trust XPS or the Graupner IFS system it does not deserve to be on the market, there are others out there that did not lie on the performance of their systems and have addressed any problems found after bringing them out, they have been up front with the problems encountered and addressed them XPS have not even admitted that a problem existed, that in itself is enough to convince me they cannot be trusted.

Mike

EDIT: The Futaba 12FG is 12 proportional channels and two switched or if you fit the MPX-1 system to channels 11 & 12 you can get an extra 16 channels yes thats right a total of 26 proportional channels and two switched.

I feel much the same as BaldEagel about XPS: we were all definitely lied to. Avoid XPS.

But in fairness, Futaba had the heat problem and has not admiited squat about it. But they did not lie and deny it either. And yes, I am flying FASST! It works VERY well.
