Mark, I like the idea of long versions of the DBRM, and MDRM. I may have to copy you.

I cloned the original DBRM (18” long BT60), substituting a 24mm mount. It flew on a C11-3 that was more like a C11-12 ... lawn-darted a few seconds before ejection event.

D*mn! That is crazy! I Have a bunch of sheet balsa, basswood and thin ply that I've had for some years. Never thought it as part of my retirement fund! :-) ;-)

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.

Which are then thrown into dumps when they start to fail in 10 years or less

I can see, maybe, paying $8.67 for a 12x48 inch piece of 1/64 ply, but not a 12 inch square one….sheesh! 1/64th ply used to be one of my favorite materials for all sorts of interesting applications….but not now.
