    Underwater signal propogation

    Tom. There is no need to to punch a hole in your watertight camera enclosure. Simply build a patch antenna and glue it to the inside of the box then on the out side of the box make an identical patch antenna solder the coax cable to the 2nd antenna and encase it in epoxy or some other resin making sure you have a water tight seal around the coax. Glue this external antenna to the outside of the box matching the position of the inside antenna, conect the other end of the coax to your 2.4 viceo receiver. Use a good 50 ohm coax, I have done this using low cost RG6 coax and sent 2.4GHz about 100 ft with out any problems even with 75 ohm RG6 coax. Use a strain relief and a don't stress the coax. Good luck and let us know how it works. Dave Jones
  2. Guys Check this out. See the list of Manufacturers on page 6. Dave. http://www.gpsworld.com/gpsworld/article/a...l.jsp?id=301693

    Diversity

    Terry Please go to http://www.klarichelectronics.com/kedrx-2401.htm and take a look at the demo video of Matt Klarich's Diversity Receiver, Matt worked here at AUAV at the time that he developed the first prototype. I have to say that the prototype was outstanding and his new versions are even better. Just so you know I don't receive any compensation for promoting Matt's product other than knowing that it will do the job for you. Dave Jones AUAV.net

    antenna splitter

    Delcam Go with the Klarich Electronics diversity receiver. I have used it and it flat out WORKS!!! there is no messing around with splitters and trying to keep the feed lines in phase. It's PLUG and PLAY. You just plug in it and it works, that simple. Dave Jones AUAV.net

    Aerobatic AUAV?

    shedao In my early days of UAV work I have had a few of my UAV's do some aerobatics, of course it was unintentional but they did some very interesting aerobatics none the less. If you go to my web site at http://www.auav.net/ and look at the video of the The Newest Twin Boom Pusher from AUAV (click on the photo) you can see it doing some mild aerobatics, I was hand flying it at the time but I can't see any reason that it would not be possible to design a preprogrammed aerobatics routine. All it takes is the time and the will to do it and the most important parts is $$$$$. Dave Jones AUAV.net
  8. Guys The video of the newest Twin Boom Pusher by AUAV can be seen at http://www.auav.net/ just click on the photo. This aircraft will get an Ezi-Nav and video camera installed in it soon. Dave.

    Possible changes at AMA with respect to UAV

    Cyber-Flyer I agree with you that there are some that will interpret the new rule #9 claming that the PDC10 or my Ezi-Nav system is a violation of rule 9 because it can be reprogrammed to fly out of sight even though it may only have one way point that is well within the visual range of the pilot. Again Rule #9 states that No model aircraft shall be equipped with devices which allow it to be flown to a selected location which is beyond the visual range of the pilot. The way that I and ALL (well most) of my fellow club members see it, is like this. If I only have way points that are well within the visual range of the pilot then the aircraft is not equipped with a device that would allow it to fly to way points that is out of the visual range of the pilot. If I was to input way points that are out of the visual range of the pilot I would then be in violation of rule # 9. This would be the same as having a computer with DOS on it as the operating system and then trying to run a application written for Windows with out having windows installed on the computer it will not do it. I would be happy to help you in any way that I can to get FPV activity legalized within AMA I would be happy to help you with the writing of the proposal to the AMA. I spoke with Dave Brown a few years back and he indicated to me that if we could get enough of us together to create a SIG under that AMA that would have to let us have one. BTW you are welcome to come down here and fly at our field. Dave. AUAV.net

    Possible changes at AMA with respect to UAV

    cyber-flyer The following is paragraph #9 of the new 2005 Radio Control safety code. 9. The operator of a radio-controlled model aircraft shall control it during the entire flight, maintaining visual contact without enhancement other than by corrective lenses that are prescribed for the pilot. No model aircraft shall be equipped with devices which allow it to be flown to a selected location which is beyond the visual range of the pilot. The way I read it, now that the word autonomous has been removed we can fly aircraft that are equipped with devices that will allow for autonomous flight, we just can't allow the aircraft to fly beyond the visual range of the pilot. We can however follow it in a car as long as it stays within the visual range of the pilot. However this part of paragraph #9 is not good for you FPV flyers ( The operator of a radio-controlled model aircraft shall control it during the entire flight, maintaining visual contact without enhancement other than by corrective lenses that are prescribed for the pilot.) I would like to see that changed and allow it to be done as long as you have a safety spotter / pilot on a buddy box where the safety spotter/ pilot could take over in the event that the FPV pilot became disoriented.

  11. Guys Wile Maynard's electrostatic wing lever worked great under ideal conditions you need to follow up on what would happen if a thunder storm rolled in wile the aircraft was flying, I vaguely remember reading about how the electrostatic field of the earth would reverse causing the aircraft to roll inverted. If I remember correctly this is one of the reasons that it was never put into production for the common RC flyer. Dave Jones. AUAV.net

    Unmanned Verhicles

    Thanks Terry. I got it, and I am very happy with the review that the Ezi-Nav received in the article. They never get it 100% correct but it's close. Thanks again Dave Jones. AUAV.net

    Terry Could you please scan the auto-pilot article and email it to me I was supposed to get a copy of the magazine but it has not arrived as of yet. Thanks. Dave Jones AUAV.net
  14. LukeZ I could not agree with you more, I just cast my vote for the new UAV forum on RCGroups. Dave Jones AUAV.net
