Joe,
1. I am replacing many aluminum parts with graphite. On my website, I
placed some pictures of the nose gear assembly including the angle bracket
and hinges - all graphite.
2. My instrument panel uses graphite inserts instead of aluminum. Use light
weight 21/4" backup insts. Use SFS or some other EFIS system that includes
most inst needs in just a few lightweight boxes. LED's are lighter than
actual bulbs. Use them for indicator lights.
3. Use RG batteries mounted in the engine compartment. The batteries are
lighter weight - they function better than wet cell and the engine
compartment mounting saves many pounds of #2 wire.
4. The overhead console is available in the graphite. There is considerable
weight savings here.
5. You can purchase graphite cowling (not a whole lot of weight savings here
becuase of the materials sandwiched in I suppose). I think the greater
advantage here is greater stiffness with less distortion during flight.
6. Drill lightning holes or cutouts in all phenolic mounting plates.
7. You already know I use graphite hinges (Carbinge) instead of aluminum
hinges.
My $.02 on a few areas you can save weight

As far as weight reducing measures, there have been postings about
Superfil,
carbon cloth Vs/ glass cloth, various nuts, washers, screws, etc. Some
very
interesting suggestions. Does anyone else out there have anymore ideas for
reducing weight? This is a issue of concern to most builders I'm sure.
