Of course the added fuel load in the wing is distributed and does not load the spar.

I called the gross weight 1700 lbs for the FAA, but it would be tough to get the zero fuel weight over 1300 lbs. The airplane holds at least100 gallons of fuel (Maybe more, I haven't filled it all the way up yet, but 100 was the goal, the most I've flown with is 55 gallons). So me and the airplane wiegh 1050 lbs and 100 gallons of fuel is about 650 pounds. Full main tanks is 45 gallons, 270 pounds, so two of me and full main tanks is 1520 lbs. Anyhow, hopefully the info you're looking for is here somewhere. > >Scott > > >--- On Thu, 1/13/11, Flyinisfun@aol.com wrote: > > >From: Flyinisfun@aol.com >Subject: Re: KIS-List: Engines >To: kis-list@matronics.com >Date: Thursday, January 13, 2011, 3:20 PM > > >Scott, > >What is your weight? and what do your anticipate your weight to be with a passanger?

Once the paint was on and without another standing along side, the differences were not perseptable to me. Makes me envious every time I see it. :-) Larry ---- Scott Stearns wrote: > The high1700 max gross is for fuel which is span loaded so it really doesn't effect the structure. My spar caps are also 50% thicker and the spar shearweb is carbonwhich more then takes care of the additional loads due to the increased bending. The material I used to make the spar caps is 50% thicker then the material rich used, so I just stuck with the original lay up schedule rather than calculating a new lay up shedule. I could have saved a bit of weight in the spar by doing some engineering, but I was short on time at the time. > > My zero fuel weight, or really fuselage weight,will not be any higher then the factory rating which is the main concern structually. My biggest concern structually is the engine mount. I have a 300 pound engine hanging on a mount intended for alighter engine. If I go to a heavy constant speed prop I'll analyze the mount. > > I extended the wing by building the wing skins a little long. I haven't seen my airplane next to a factory airplane yet, so I'm not sure how different it really is.
