I have a problem; I belong to a flying club that will not let you fly your plane if it has a Db level higher than 95, measured at 25 feet. I have a COMP ARF Yak 55sp 3.1 meter, ZDZ 210, KS1090 pipes, 3 blade 31 x 12 Mejzlik prop. I aspire to fly it 3-d. Is there anything that I can do to lower the Db level, and still maintain good 3-d performance? The plane is a great performer as is, I hate to mess it up trying to put different prop that could possibly reduce the noise. I looked around, and I really don’t see any prop that is larger, or with more pitch that’s off the shelf. Anyone have any good Ideas? other than join another club, or reduce your ATVs for the test, I already have that idea on the back burner.
