Speaking of power

[ronlock]

Noise isn't the only reason we loose or can't get flying fields,
but it is a factor within our control.   I'm pleased to be part 
of a community that leads by example.

  We all should be. The number of flying sites lost each year, especially on the east and west coasts due to noise, is a crime. Long term noise reduction/enforcement for all models should be an AMA priority, plan and goal. Unfortunately the almighty buck spent on advertising seems to get more attention and takes priority. Pattern flyers as a community have and should continue to lead by example in this arena.

    Who's pressing for lower noise?

    Based on all other models... our pattern planes are by far the quitest airplanes in the air.  I have seen a few IMAC's that have the noise down some but they still get a good prop rip at speed.  The .15 to .60 size engines make an iratating high pitch whine. 
     Why is it that the pattern planes are some of the quietest yet we are still pressed for lowering the db even more?

    Thank You for making my point Tony ... actually I am even more concerned with the subjective in-the-air noise. 
    I fly at a beautiful and genuinely noise-sensitive site (1/4 mile from the site of Washington's crossing the of the Deleware on the Jersey side). 
    I don't even look at the meter anymore: my ears are tougher!

    Actually, it's 2 db OVER if your flying at the Team Selection Contest!  Yes, these high-power engines turn bigger props, so noise is a factor...

    Has anyone measured the sound levels of the larger two strokes turning the big props?  We measured a YS140DZ with ES pipe turning a 17X12 APC and came up with 96dB, right on the limit.   Just curious.
