[NSRCA-dist8] Foam Cores

[J N Hiller]

I pulled the trailing edge forward about 3/4" narrowing the tip and
effectively reducing the 'as cut sweep' slightly. Actual sweep is fixed when
the tube hole is cut. The other change was to flatten the surface from the
aileron spar rearward, the original had a continuous radius from the high
point to the TE. I found it more difficult to work with finishing the
ailerons.

Jim,
Would you explain the difference between the old and new 160 cores?

55 is a built up wing (at least that what the plans show).   I would like a
set of 160's also, if you are going to make some extras.    I think I have
enough 120's to last for awhile.

Thanks

OK guys, who wants foam cores?
I picked up some 2" foam yesterday and I'm preparing to cut some more
Option-120 cores when I cut new 160 cores.
