Hi Rusty,
I can understand your frustration at this point,
but consider this. You have an RV-3 which if I recall correctly is doing
way over 200 mph with an outstanding rate of climb with no major problem (oil
cooler excepted). Plus even if you do end up rebuilding the engine, you
will probably spend less than $2500. You really have 90 % of the bugs
worked out - the major exception being the oil cooling.
I would suggest going to the stock oil cooler (of
which I have not heard of one failing - at least on an aircraft) oriented it
longitudinally and you should have room under you cowling - Ok, so you would
have to do some more fiberglass work, but you should be getting good at that
{:>)
Besides, if you got to building an RV-7
who would we have to entertain us rotary folks for the next year or
so??
Seriously, I envy your performance which is
starting to knock on Tracy's door, so why change horses at this point when you
are just starting to reap the benefits of your work. Just my viewpoint of
course.
Good luck on whatever you decide.
Ed
