Just finished riveting my rudder trailing edge. It came out straight, but I
have some "pillowing" between the rivets and places where the 2 skins and
the wedge are not quite together. I used T-88 to glue it together, should
anything be done to "fill" the TE at this point?

A large percentage of RV's including some of the factory birds,
have some pillowing between rivets of the trailing edges. This
has no significant impact on the airworthiness of the plane.
Whether to do further work to close up the trailing edge is really
just a personal decision.

This may be irrelevant, but it is food for thought.
A few years ago I read a biography of Bill Lear. The original Learjet broke
up in flight. The investigation found that, after flying through rain
clouds, water had accumulated in the elevator trailing edge throwing off its
balance resulting in catastrophic flutter. The point is to be sure that any
changes in trailing edge design do not adversely affect the intended means
of control surface drainage.

I had pillowing also, so I drilled out the rivets and would like to use and
adhesive and cleco to a flat table. I read of one builder doing this with good
results. Can anyone recommend an adhesive and where to get it for this
process. Thanks

I used the T88 Structural Epoxy listed in manual and clecoed it to
the elevator spar (same hole spacing) worked ok. Make sure the leave
the plastic on the spar and clean excess with vinegar. I checked
around and found a local wood working store that stocked the epoxy.

Thanks for the info. I have an older kit and there is no mention of T-88 in
my instuctions. Steve.

Steve,
I used ProSeal from Aircraft Spruce. It's available at many aircraft supply stores. I think even Van's sell it. From what I have read on the newsgroup, it seems a lot of people think it is a pain in the emp to deal with, but I really didn't have a bad time with it. Of course, I haven't gotten to my fuel tanks yet, so I may have a different opinion after that. The ProSeal worked like a charm for me on my emp trailing edges. Hope this helps.

Good advice. I saw a number of RV's leaving Oshkosh ("Oshkosh" is the
sound a boot makes in deep mud? curious...;^) after sitting in the rain
and noticed a lot of water draining out of peoples rudder bottoms. If
this were wintertime, those would have been sizeable blocks of ice at
a very long ARM. Make sure your control surfaces drain when sitting level
as well as in-flight positions.

At Osh, during my RV6A preflight I discovered the lower rudder tip was full
of rain water and proceeded to sponge it all out. Drain hole had been
plugged with dirt.

Hi Dan,
I have finished my rudder trailing edge per Van's instructions. After
priming, pro sealing the corner edges, mine has a pretty good fit/seal.
There was nothing in the plans that mentioned drainage, or allowing rain to
drain through the trailing edge. You do bring up an interesting point
though.
