We were discussing aluminum side and intermediate housings a couple of
weeks ago. A figure of somewhere around 15lbs per housing in weight
savings was thrown out. The exact figure isn't as important the fact
that several Delta builders have had to stack approximately that much
weight in the tail to get the proper W&B.
Ernest,
Surface treatments are problematic- no real cost effective treatment as yet.
Composite( aluminium and steel) housings don't save that much weight, I
forget the exact figures but will save about 30 lbs, at best. A hell of a
lot of work ( and cost) to get that 30 lbs.
I tend to agree with you, George, but you have to balance the work required to remove 30lbs from the engine against the work required to remove 30lbs from my slim figure*. I won't even consider aluminum sides until I do a (semi) final weight and balance. If it comes down to aluminum housings or more junk-n-da-trunk, the debate will be wide open again.
(The humor will be apparent when you get to the email where Ed tells me that I'm a little stout for his RV 8*)
