Thanks Joe, very interesting information.

 

Please note, however, that I am primarily an outdoor FFer, not an
"indoorist" concerned with every last 0.1% of performance. Those guys are
here, though, and they will undoubtedly chime in.

You sure can make a rubber motor do its stuff, so if you leave the oil on it
must be OK. The silicone oil has a listed shelf life of 60 months. I've used
it in heating baths and it's pretty stable. It does dissolve oxygen ( see
mice immersed in it still breathing and the "Abyss" movie)and latex rubber
is sensitive to oxidation. The big question is "how much does it soften the
rubber?". We've all seen rubber stiffen with age under the influence of
light and air. Experience would set a time and flight number limit on these
motors, stored out of light. Maybe Mike Kirda could take some loops of his
rubber and stretch them over some nails in a board, with and without lube,
to give a "days to break" number.

Thanks for the tips

Joe
