I've run many 'what-ifs' in the W&B spreadsheet on 41CC in its previous trim and can tell you a couple of things that the numbers show on this airplane. And it has a Continental A65-8, cabanes swung back 4", and split axle Cub-style gear. And I'm 55 and not "oversquare" in the waistline (32" on a good day, before dinner, without tucking in my shirt).One thing the numbers show is that my airplane should only be soloed from the rear seat, especially with full fuel (16 gal. in a header tank). Another thing is that there is a minimum pilot weight, solo with full fuel, of about 95 lbs. or the CG is too far forward. Another thing is that it's virtually impossible for the passenger's weight to affect the CG... I've tried passenger weights up to 350 lbs. with a 95 lb. pilot and I really don't believe that can physically be done by any 350 pounder I've ever seen. More realistic passenger weights do not change the CG to any appreciable extent.So... to your question. "Useful load" for 41CC is a pilot, passenger, full fuel, and a couple of headsets. There is essentially no place to put baggage, certainly not behind the pilot. On this airplane, that amounts to roughly 500 lbs. available for pilot and passenger. I've run scenarios (on paper) with large pilot and passenger and full fuel and you can put the airplane out of CG limits and over-gross, but I really don't believe it's physically possible to stuff two people that large into both cockpits, especially into the front. And more than that, my understanding is that the A65 won't pull the airplane up with any gusto in this configuration, especially on a warm day or at anything much above sea level.I'll let you know how the new W&B turns out.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net_________________________________________________________________Fixing up the home?

Hey Mike, One day ol' Forrest and I were talking about the props so we checked his and itwas a X 44 on Sky Gypsy, which surprised me and didn't make me feel too goodeither! I've kinda been looking around and thinking about a flatter pitch. Trees at one end and wires at the other of my home base. It's about 2500' longand I can get 250' by the end of the runway now but as you know it's a differentairplane in the summer with a load. Thinking about going to a climb prop. Thanks for the comment on the plane, I suppose I'll have to buy you breakfastnow if I see you at a fly-in this year! Thanks to global warming I've flown eachmonth now this winter. The runway is a sloppy mess with a lot of it stuckto the plane! Don EmchRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
