Joe Nall 2016, Official Noise Policy?

Discussion in 'Joe Nall Week' started by Bartman, Jan 13, 2016.

  1. The Last Post is from AMA 2015 Manual about how sound is measured .

    Is there any questions about the sound issues ?

    I'm investing in a couple three blade Biela props for my DA120 ,they were the best fit and i could get exactly the diameter and pitch suggested .
    Also i'm using plane blender smooth pipes to reduce the exhaust noise , all together it getting a little pricey but its better than the neighbours complaining to there local MLA district and filing a noise complaint about our gas powered aircraft . My hobby .
    Its a hugh issue facing the gas powered aircraft that i fly but we all can over come these obstacles and still have a great flying field with a good future :D
  2. Err.o_O I'm confused! I had thought, when we left this on one of the other GSN post, that these were all suggestions but not "requirements".:concern:
  3. Where i live noise is always the issue when the club is asked to leave .
    Remember i raced Formula one r/c airplane for ten years , back in the days we were the worst offenders at 130 db .

    Sorry for venting:cautious: but I am concerned about this sound issue :fist_pump:

    They are. If they got rid of anyone that did not fly cans and 3-blade props it would be an electric line, control line and a dozen or so gas guy's. Oh, and the German guy's.
  5. I don't remember exactly when at the end of last years Nall but I talked to Wess after the FG post and all of it was a suggestion. They will however be strictly enforcing the prop rippers without question I think is what he said. Not quoting him exactly.

    This should help clear everything up.

    Well, we certainly got lots of attention with Part 1 of “Joe Nall Week 2016 – Quiet is the Word!” It seems that our carefully worded (for clarity) communication was not very clear at all. As a result, the internet has come alive with individual interpretations of our intent. Come on guys and girls, you know us too well to think that a group that routinely goes all out to make certain you have the time of your life and enjoy the very best of modeling is suddenly going to require all kinds of expensive do-dads and exotic rules.Our intent in the previous article was to inform you of a needed change for the next Joe Nall and suggest ways to make our models less irritating to those nearby that may not share our love of endless RC noise. Triple Tree has great neighbors. They like us and we like them. With our growing Triple Tree events, it is imperative that our relationship with those living nearby remain cordial. In the past, the Joe Nall event had a neighborly experience that didn’t turn out well at our old location. They complained and left us with no choice but to cancel the event or move. Thru the generosity of Mr. Pat and the hard work of many, many dedicated volunteers, a new location (Triple Tree) was the result and Joe Nall Week continued at a new, spectacular location. We cannot and will NOT allow that process to begin again. Mr. Pat, our guests and our volunteers have WAY too much invested to potentially lose Triple Tree and Joe Nall Week again to noise complaints.

    Joe Nall is, by far, the largest, busiest and longest running Triple Tree event of the year. It’s also the noisiest. As some internet posters have noted, we do have full scale events and full scales do make noise but most of our full scale arrivals are small, low powered models that arrive and depart a single time for each event. Our full scale pilots are constantly reminded of our neighbors and specific “no-fly zones” are posted on our website to protect the areas around our neighbors. To be clear, this noise issue, at this time, is a Joe Nall issue.

    So, what’s the issue? The answer is simple. Our own Triple Tree personnel have noticed for years that there is a very IRRITATING sound emanating from this event. We know this IRRITATING sound is caused by a small number of pilots and their planes. Through the years, we have begged, pleaded, counseled and tried to educate these pilots on quiet flying; all to no avail as it continues. So, for Joe Nall 2016, there is only one requirement … it is non-negotiable and will be enforced.

    That requirement is that Joe Nall 2016 MUST be the quietest ever!

    A recent AMA study states, and we agree, that the majority of this IRRITATING noise is caused by “PROP RIPPING”. The sound carries for tremendous distances and is a potential real source of irritation for those living beyond our property lines. Obviously, other factors can cause additional noise but make no mistake; PROP RIPPING is the primary source of what we view as THE potentially troublesome noise and is the focus of our efforts. WE would certainly appreciate anything our guests can do to make their models even quieter but, for prop ripping, more conservative throttle management or in the worst case, a three bladed prop should take care of the issue.

    What about our monitoring? After much discussion, we have determined that DB monitoring as described in the AMA study really fails our needs as it is complicated, distance and height sensitive, requires expensive equipment and doesn’t accurately measure the “Irritation” factor. So, we’re looking into possible solutions ranging from the ultra simple (line judges) to our dream solution (an iPad app that measures frequencies and identifies the irritating range. This one could be made available to the entire modeling community). We are working on the iPad solution so if there are any app designers that would be willing to help, we’d sure like to hear from you!

    We would like to hear from any of you that have had a similar issue and found great solutions. We welcome your ideas and input. Please feel free to email any suggestions to:

    The way I read it was don't be too loud. However you accomplish that is up to you. Just know if theybpeg you for being too loud you'll be grounded. So if you rip prop at 1/2 throttle you might want to prop up

    Simply put, don't be obnoxious with your airplane. Nobody is making you cease the full throttle fly-by's, just prop your engine accordingly and you can haul around all day. My DA120 doesn't rip the Mej 29x10s it swings even on a WOT downline.

    I fear I may get kicked out for a noise violation as the smile on my face will be so loud everyone for miles will know about it.
