I delt with Scott most of the time at Nall and we switched 2 planes over, a 33% Laser and a 46% Ultimate, We may be one of the lucky ones or something but there were no issues the whole weekend with either plane and Scott was more than helpful with all issues. I also bought the system for my 42% extra and installed it this past weekend with 7 flights and no issues, I was unaware of all this mess beforehand and sure hope it all get resolved. We simply ripped out all regs on receivers and bought the smart fly expander and run full 7.4 volts on system, hope all troubles stay away from us.

We also had another XPS Rx go into the so called 'Zombie' state last Sunday at our heli club. It was fitted in a Gasser machine and was fed with a dedicated receiver battery (servos fed off their own separate isolated battery). Luckily for the owner the Rx locked up just before takeoff and the machine just sat on the flight line at a lowish throttle setting, so no harm done to the model. Once we manually shut the motor off, we went over the installation and the Rx was sitting there with a green steady LED but there was no response from the servos - It did NOT go into failsafe, and at all times the pilot was no more than 10 feet or so from the heli. Checked all batteries etc and all OK.. It was not until we cycled the power to the Rx that we gained control. Needless to say the owner was very lucky to not lose the machine or cause an incident etc. I am certain he is now purchasing some Spektrum gear as I write this...! This is the THIRD time XPS receivers have locked up into a 'Zombie' state on 3 different machines (2 different owners) at our club - Luckily the majority of us are not flying XPS and these only two XPS owners (in our club) are currently in the throws of switching systems. I am convinced that some sort of firmware problem causes this problem as it does not occur all the time and the two guys have had quite a few successful flights with the same setups previously. After these three incidents they cannot trust XPS anymore - As a matter of fact, I would confidently state that all of our club members would now only purchase Futaba or Spektrum/JR 2.4GHz gear at this point in time.

Then again, he says that he's tested the firmware and is 100% certain there are *no bugs*. This shows a naivety beyond belief and is *not* something that any software engineer would *ever* say, for fear of being ridiculed. As with the hopping issue, JD seeks to simply deny things that don't tally with his view of the world. Unfortunately that means that users of his gear can find their support requests summarily dismissed as being "impossible" or due to something *they* have done wrong -- without any real investigation or willingness to accept that it might just be a problem with XPS. I feel sorry for Xman2004 over on RCG who had his very genuine help query handled in this way. Not only that, JD deleted the thread in which he asked for help. There were no accusations, no challenges to JD's word -- a simple description of the problem and a request for help. It seems that JD won't have any talk of problems with XPS, at least not in his support forum. I think perhaps the word "support" becomes a misnomer when the only postings that are acceptable are those which praise the system and berate anyone who'd dare bring a fact or two into the area. But I see those unexplained XPS failures continue to mount at an increasing rate -- another since I looked earlier today, and now there's a growing amount of *unused* XPS stuff being flogged in JD's own forum by people who have got cold feet after seeing the way JD behaves. The pigeons appear to be coming home to roost.

I fully agree that the FAAST Rx install is pretty much a no brainer. Having tested it in some less expensive, and easier to get over if I lost, planes - I've put it in my 3 year old Corby Starlet. Great range checks, now waiting for the right weather this weekend. Already flown in my Quique Yak, flawless performance. And I sure feel safer flying now. |

![]() I'm HOPING that someone can get it on VIDEO. . this "receiver has a solid green light, but no one is home" phenomenon. That would pretty much put all the excuses to rest from XPS and JD.
