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

Regards,

Regards,
