[NSRCA-discussion] Spectrum and Hobbico... new 2.4 alternatitve

Wed Sep 23 12:53:24 AKDT 2009

Tony, JR has nothing to do with Graupner-IFS system. It's an Extreme Power System developed right here in Lake Havasu City, AR. Graupner just changed the name from XPS to IFS. As for which system is the best? Must be DUPLEX by JETI. ed

  JR is not Spektrum..  JR has been selling 2.4Ghz frequency hopping gear in Europe for almost a year.  Check it out under the Graupner name.

  For all the info go to  http://www.graupner-ifs-system.de/en.html

  The issue isn't whether frequency hopping is better than DSM but rather will JR stick with DSM indefinitely.  I don't want to spend $1400 on a new transmitter that will be out of style in the near future.  Matter of fact, you can buy conversion kits from German companies (Weatronics and ACT) that are better than both DSM and FASST.  The Germans use frequency hopping where the transmitter and receiver talk back and forth to each other.  These German systems aren't cheap but they are certainly better than what we have in the US.  Regardless of what system you go with 2.4 GHz is better than 72 MHz.

  Are you aware of situations where DSM doesn't work?

  I'm still flying 72 MHz using my JR 10X radio.  I need to switch to 2.4 this winter.  This module is the solution to my problem.  I love the 10X, 9303 and 12X radios.  I don't like the DSM2 technology, I feel frequency hopping is a superior technology not to mention you can't use DSM2 in Europe.  Either Europe will eventually approve DSM2 or JR will switch to frequency hopping worldwide.  This solution will afford me more time to see what JR decides to do.  So I plan to try this module out on my foamies and park flyers and if I experience no problems I will use it in my pattern planes come this spring unless JR makes a switch to frequency hopping.  I know there are a lot of people in my situation.

  In all seriousness, I think it makes little sense to cross over brands this way.  FASST, JR, or Airtronics; things work just fine.  I could see the initial idea that Horizon had with Spektrum to get the world moving to Spread Spectrum with their modules, but I think that time has passed us by.  As far as preserving the value of an investment in a transmitter by moving to another brand of receivers with a module - why? Go with a brand you like and don't look back to gimmicks to cross over part way.  You always lose something in the process.

        Personally, I like the FASST system. I must have a dozen 2.4g receivers now. I have nothing against the JR/Spektrum, a lot of my friends fly JR (I am in a very small minority in my club flying Futaba). I will admit that I bought the Spektrum module for one of my old Futaba transmitters, so that I could do the "bind-n-fly" thing as well.

        I will tell you guys a funny story. I was at Efest this year. I was flying a Vapor over in the corner for the ultralight planes, and heard someone walk up behing a friend of mine (Jeff Phillips, Radioactive Airshow Team) and start asking him how he liked the Vapors. Well, I thought it must be someone who had never flown a Vapor, so I turned around and handed him my transmitter, an old Futaba 7UA with a Spektrum module, so he could fly it. It happened to be Peter Goldsmith. :-)  I wish I had said "feel the difference" to him.

                You are a one-percenter among the one-percenters! LOL 

                I actually bought the Spektrum module with Rx for my Futaba 12Fg because it was such a good deal. I'm going to use this setup for indoor this year with some of those really small Spektrum receivers. It's also great for the E-Flite Bind-N-Fly models. I just didn't see the point in going "the other way" but I guess in your case it makes sense.
