Review the first chapter in the builders manual for these definitions, but
in general when the manual calls for flox or micro (wet, dry, or slurry) or
expancell the presumption is that you will mix these materials with the
same epoxy used to wet the glass cloth (the epoxy that came with my kit was
---From Aeropoxy - yours may be different). The fast cure (five minute) epoxy
is not an acceptable substitute for most applications, so unless
specifically called out, don't use the five minute epoxy for anything other
than temporarily holding things together. A third epoxy system was also
supplied, either called Redux or Araldite, and when this is required the
manual will be quite specific. It is used as a structural adhesive, for
such things as joining the top and bottom fuselage moldings and the cockpit
module.
Dry micro is the preferred filler for those glassed foam core joggle areas
that need to be "leveled" to match the surrounding areas, such as at the aft
edge of the rudder, ailerons, flaps, etc. .
Because the whole point of using micro or flox is to reduce the density of
the mix and thus reduce the weight, dry is better than wet. The trick is to
get the mix as dry as possible but still allow the stuff to be spread
easily, something that comes with experience.
I can not find any reference in my manual to using rapid epoxy and flox for
the anti-servo tabs. In general the manual IS correct and any errors that I
have found are not related to which epoxy to use.

Subject: Europa-List: What type of epoxy/mix?
<rparigor@suffolk.lib.ny.us>
Finally getting going on A-265 Monowheel
Have a few epoxy questions:
What type of epoxy is needed to bond hinges on Rudder and Anti-servo tabs?
Manual calls for Epoxy and Flox for Rudder, and Rapid Epoxy and Flox for
Anti-servo tabs. Is the manual correct?
What sort of fill is used to fill in the joggle on the back of the rudder?
Is
Dry Micro OK?
The manual shows filling in a similar joggle on the anti-servo tabs with Dry
Micro, but it gets a strip on top of it.
Thanks
Ron Parigoris
