  • Got it Chris, thanks for the info, It is almost same over here too, private/ hobby pilot are resisting the change over to S mode, I fly ultralight with couple of other guys here, but I guess transponders aren't that bad thing to have in ur AC unless there is no primary radar coverage and no one listening on squawk :) , Any way don't you think we should be ready with micro transponders for out hobby just in case

    Morli, the problem with transponders (at least in the US) is not technical. It's that the private pilots ("general aviation") don't want to carry them. They practice "file and forget" on their flight plans and love the freedom of being able to fly anywhere outside of urban areas without anyone paying attention. It will take a lot of political forces to get past their associations lobbying against transponders...
  • Any one working on mini/micro transponders? I don't want my 2 k.G UAV equipped with 2 pound transponder,!! having worked with SBS-1 I assume it should not be herculean task for PIC/similar proc based transponder to come out, if any S mode micro transponder is available , kindly point / link is highly appreciated. Thanks
  • This is always a heated topic, personally I am fine with 400ft AGL. I have been flying in that range since I started RC back in 1976. I have no problem with that at all, if its 700ft even better. Although I did not see 700ft as an option in the latest ARC report, unless I missed something.

    The facts though would indicate the average AMA registered club field has plenty of RC flyers breaking that altitude limit. Turbine jets break it consistently. Glider pilots do as well, so it will be interesting how much this is enforced via AMA if it does hold to 400ft. As I have been to 1000s of flyins around the USA including Joe Nall, and 400 ft is more like a starting point reference - LOL....
  • George,

    I am interested in knowing as well, how are you transmitting your location without a Transponder ?

    George how do you transmit your position to other aircraft?

    If your flying within VLOS below 400' you should'nt need a transponder.

    Otherwise get one of these.

  • Why should we need transponders when we already transmit our location?
  • I have not yet had a chance to read the ARC report, so perhaps this was addressed, but one idea I had was that would be interesting for them to make additional airspace available to UAVs that are equipped with transponders. This would be done to encourage the development of lower cost transponders and hopefully make things safer.

  • Thanks a lot Paul! Maybe next time they will keep it in mind that it should be downloadable as soon as it's published.

    Note sent to publisher. I'll let you know if I hear anything back. Otherwise, check the download link again later today or tomorrow.
