Hi Ed,
What kind of glue did you use?
I have been told
that shoe goo is wonderful stuff and will stick to
anything. Well, it
doesn't stick to silicone baffle material very well
at all! I used
rubber cement, and it works much better, but I'm not
sure it will hold up
to repeated installations. You may be using a
different material for
the seal, but I thought I would ask.
Thanks,
Bob W.
I
discovered that the max temperature of Velcro is 200 C. Has
anyone
tried using Velcro to attach the fiberglas plenum to the
coolers? This
temperature is twice the normal temperature of the oil
and water...The
only consideration should be the glue on the backing of the
Velcro??
Any comments on this application?

Really, RTV works great and can be removed on those rare occasions when
required (haven't had one in 12 years of flying rotaries though).
