Years ago, we used 1/64 ply to skin foam wing cores for R/C Pattern aircraft.
The local hobby shop now wants $25.95 per 12"x10" sheet, which is beyond ABSURD.
At that price it would cost over $200 just to skin a main wing.

I blame all this high wood price on the idiotic wind power industry using all the wood for prop blade cores.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
