I don't know you and I don't want this to sound offensive so don't take
it that way. Are you an aeronautical engineer with enough experience to
feel comfortable giving someone advice, enough so to not worry about
liabilities, regarding structural changes? If you are, what data do you
use, other than you think it is weak, to support modifying a structural
assembly without knowing that it won't adversly affect the safety? Once
again, there are too many of these flown stock to warrant any changes,
especially by a someone who thinks it looks weak. Remember, no offense
intended. I think that if you were to talk to Richard VanGruensven he
would tell you the same thing. He actually told me that he thinks I
"....bastardized his design and made it unsafe...." by converting an RV4
to a Harmon Rocket II, and the only changes I made were per John
Harmon's design, which had been engineered. If someone takes your
advice, that is their problem, but I wouldn't make any changes in the
structural design without an engineer's wet stamp.
This is just my opinion and no reflection on your abilities; please
don't get offended.

Well I did stay at a holiday Inn express last night and yes I do have a
degree in aero engineer, but I would conceder my self an amateur in the
field.
I was just telling Chris what modifications I made to my tail, take it or
leave it.
