Are there any estimates as to how much weight it has added to your plane?
I'm assuming that hydraulic fluid must weight between 5 or 6 lbs per gallon.
I imagine that over the years one could gain quite a bit of unwanted weight
from prepreg soakage.  I plan on finishing the entire bottom of the belly
pan and fuselage back to the forward wall of the aft bulkhead in the baggage
compartment where I will install the power pack.  Then all the way forward
to at least the forward spar and out board to the BL 50 rib.

Another note:  aircraft hydraulic fluid is almost as bad for you as any
cleaning agent that you can imagine.  Your skin readily absorbs it and if
you get it in your eyes, you might as well not plan on flying for quite
awhile.  I got some in my eyes (very little from film covering my hands)
when I was in the service, and the result was swollen, pussy, pink eye for
about 2 months.  Another guy was on a drug known as antibuse for those
sailors that couldn't control their drinking.  He got one drop of hyd. fluid
on his hand and it sent him to the hospital for a week.  I guess hyd. fluid
and antibuse don't mix...hehe.
