Does anyone know where I might source a borrowed or rented set of scales? Thanks! Dennis Ballew Vice President Las Vegas Valley Soaring. Schweizer documentation indicated that, if no big scale is available, use 2 bathroom scales with a board across them. FWIW UH Electronic scales that measure up to 300 kg are available for under $100. I calibrated a pair of bathroom scales by going to an immediate care clinic with a backpack loaded with about 50 lbs of weights. I asked to use their patient platform scale, which they gladly agreed to. I weighed myself with and without the backpack. I then weighed myself the same way on both bathroom scales (they were surprisingly accurate). The most critical measurement is the tail weight as it has the longest moment arm. I would check the scale this way as close as possible to the expected tail weight. One thing to keep in mind is that any breeze will upset this measurement. Either find a hangar you can do this in, or go out early and do it on a calm day. Tom Buy 3 of these for $34.99 ea free Prime shipping. Make a ramp to use 2 on the main wheel and one for the tail. 440 lbs capacity ea. https://www.amazon.com/Smart-Weigh-S...xpY2s9dHJ1ZQ== Richard |
