why use paper honeycomb, a foam form would be easier to shape accurately

Indeed.

I did the sums, and it seems that paper honey comb would come out a
good deal lighter. That might be OK for fixed wing, but no good for
rotary, the original application.


interesting, but accuracy in the forms would be my greatest worry,
especially for a lifting surface,
how would they compare ??

Funnily enough, one of my old students was an engineer on that rotor
fabrication at PZL.

Getting the building bug?

Had it for a while Paul :-)

Excellent.

Just need to clear some space out in the garage for a start, I have been
reading and researching this for a while now and have even put a dent in
the
list of tools required (though we all know that Murphy was an optimist )
The
biggest hurdle I have is the sub 0 temps we get here in winter so laying
down the skins and curing is only a summer prospect here :-).
KR forums are a wealth of information and most times Google is your
friend.

Stinky stuff. I prefer metal myself. It's so easy to have subtle
flaws concealed in that resin based stuff.


considered metal and rivets but early on I came to the conclusion that I can
put a dent in armour plate so working with thinner materials is a dodgy
prospect :-)

I suppose you are thinking of one of those foam cored canards?


KR2 with foam core wings seems to be a good prospect and having learnt
laying down of glass and resin at high school I do have some experience with
it :-)


VH or RAA?

still RAA, not enough disposable income to cross over to VH just yet :-) If
ever, I don't see a need just yet for carrying any more than one passenger
ATM and RAA registered AC that are for sale are still thick on the ground at
reasonable prices if I decide to buy.
