REFLECTOR: Interior foam

I've been hearing about various products that builders are interested in
putting in their Velocitys. I've got a LWFG with an IO-360 with
hi-compression (10:1) from Lycon that, they say, has dynoed at 230 hp.
My recommendation to anyone building is "Keep It Light". I'm empty at 1630
lbs and if I had to do it all again, I would build it lighter. I put in
nicely padded leather seats, thick aviation carpet, fiberglassed a keel
cover with glove box, re-designed instrumental panel, tool box below rear
shelf, a loaded instrument panel, constant speed prop, etc. etc. My payload
is only 770 lbs. (360 lbs for full tanks leaves only 410 for adults and
passengers - not much). A two hour trip with 4 adults and baggage from PHX
to LAS required 1/2 tanks (30 Gallons) - not a very comfortable fuel margin.
Also, I can tell you that you'll fly slower heavy - I would have loved to
have seen more speed out of my plane. If you're going to wear headsets
anyway, why put the extra weight in insulation? If you need more heat, they
are probably other ways to get it without adding much weight. Most of the
stuff we put in our planes, we don't use very often and probably wouldn't
miss those items.
Happy building.

Sounds good. Any idea what it weighs?
