Jim Peace Posted April 4, 2016 Report Posted April 4, 2016 Anyone ever seen this before: https://www.balancemasters.com/aircraft.html I saw it on a certified airplane last week and from what I can tell it is only good for experimental.....The owner swears by it and it makes your prop balanced immediately at all RPM settings. Some guys even put it on the main gear..... Has anyone seen this on a Mooney?
Hank Posted April 4, 2016 Report Posted April 4, 2016 Their website talks about ultralights and Rotax engines. I'd be shocked if it's approved for certified use. by the way, their "high density liquid mass (Quick Silver)"--quick silver is the old name for mercury, which is certainly a high density liquid (density = 13.7!).
carusoam Posted April 4, 2016 Report Posted April 4, 2016 The lack of information or technical data like a drawing is enough to say, save your money... it fixes everything like "from nicks and rocks during takeoffs and landings." The intentional hiding of mercury (Hg) from their ad is telling something. They don't mention the diameter of the device. But it is less than 7". The weight is 'about' 4oz. it's a 'must' for ultralight safety... installs in 25-30 minutes... cuts the 'vibration factor in half'... I tried to read the installation instructions, but they were not complete after three lines. ---------------------------- Dynamically balancing a prop has demonstrated measurable vibrations being cut by a factor of 10. Dressing a prop properly and balancing it doesn't seem to get mentioned, but neither does certification. ------------------------------ Sounds like you may get an empty box for your money. If you are lucky you get a placebo effect for your money. Best regards, -a-

DonMuncy Posted April 4, 2016 Report Posted April 4, 2016 Some years ago (probably 40 or more), some outfit sold circular tube devices with steel balls rolling around inside, that were designed to mount behind the wheels of a car, to balance your wheels (tires) with this same theory. I never found anyone who tried them.
jetdriven Posted April 4, 2016 Report Posted April 4, 2016 My Samsung washer has that feature. They call it VRT. 1
