Ryan;That is exactly what I did to determine the moment arm of the pilot and passenger,and it came out a bit different from the "belly-button" method. Very easyto do, as long as whoever is doing the weighing remembers to weigh themselveson the same scales either before or after weighing the airplane.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:

Jim Hyde, this discussion is not intended for you, but you're welcome to read on.Since my previous post on this subject had no calculations behind it, I'vedecided to run some numbers for my own information. Anyone else who is interested,I'll use this thread to keep the discussion separate from Mike Cuy's W&Band out of the hands of those who don't care. If you are of the opinion that"it works, leave it alone" and "I'm just going to bump my own airplane's maxgross to 1300 because other guys have", then please use your key when you seeposts with the subject line "spar strength".So is anyone using a 1" thick spar anymore? My sense is that everyone uses eithera solid 3/4" spar or a routed 3/4" spar these days. The few who build boxspars (the UK style) are in an entirely different category, because that sparwas developed with both calculations *and* load testing behind it. My interestis in running the calculations for those who build to the plans.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:
