Not it it was required, but why you guys did it. Kevin do not archive dougsnash wrote: > > The interior of all aluminum surfaces were primed.

I think considering the options, even if you never implement any of them, is a good way to fill extra time you may have and to keep construction/creative juices flowing. Every ounce you can save has benefits. And it IS called experimental aviation. Of course one big question is always the cost/time/benefit relationship. For more specific thoughts I would look at experimenting with things that could be more easily changed. I saw one somewhere that had a carbon fiber instrument panel. I am looking at maybe using composites on my 750 for the seat pans, control sticks, pedals, muffler bearings, and who knows what else. Every design is a collection of compromises, maybe you can find a set that suits you better than the designer's original.

As lightweight as it is, it seems like there are areas where you could take advatage of its modular construction and use carbon fiber to save a few pounds. Some of the steel pieces like the rudder pedals could be replaced. If you accounted for the COG shift you might be able to fabricate all the tail section pieces and flaperons out of carbon fiber. And if you did some honest-to-goodness engineering, you could switch out the landing gear and make some aerodynamic struts. > When I get home I might weight the parts and pieces and do some back of the envelope calculations and see what kind of weight savings a person could expect. > Has anyone else looked into this? I've already finished all the major modules of the kit, but it seems like it would be an interesting way to continue to the build/experimentation phase after the airplane is done. > I would be interested to hear your thoughts. > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=312491#312491 > > ________________________________ Message 3 _____________________________________ Time: 06:32:56 PM PST US Subject: Zenith701801-List: Re: A lighter 701 From: "Benjamin Q" I love to fly and getting in the air is my first priority. But one of the reasons I settled on the 701 kit was because it hold a very distinct plane in the experimental aircraft world as a STOL aircraft. I think its exciting to already be at the edges of STOL performance and still be able to make a meaningful design contribution. I wonder if it is possible to bring the 701 to under 500 lbs?
