Hi Rusty,

    Yes, got it back together just in time to fly it to Sun & Fun.  However,
given my history with unique problems, I did not adjust it while airborne
550 miles away from home and my tools. So I have not even begun testing.  I
plan to swap out the current lower manifold which I made for my first engine
out of two slabs of aluminum as I know it has poor airflow characteristics.
I used it simply because it was there and mainly wanted to test the
mechanism for adjusting the intake length.  So I am going to either find a
better lower manifold or more likely I will have to have one made as my
motor mount interferes with almost anything designed for the 13B engine.

   It turned out the tubes did have some bubbles in the plating, but I used
a stiff wire brush wheel on a drill to remove all the bubbles and loose
stuff.  99.9999 percent of the nickel bearing surface remained, so for my
purposes the nickel plating worked fine - it just bothered the plater {:>).

   I ran it up and down at Sun & Fun for numerous folks, manage to leave my
master switch on all night once as a results and had to get a jump start.

   I will report the results as usually good, bad or ugly once I start
testing in earnest.

However, after seeing Tracy Crook's VSTOL take off with the 2.85 and monster
75/88 prop, I decided that I want one {:>).  So depending on timing, I might
have to delay the intake testing a bit.

By the way a Zinc coating is used to temporarily  protect the aluminum from
oxidation after the aluminum is cleaned, the nickel acid bath then removes
the Zinc and coast the aluminum with Nickel.  The nickel plating on the gear
box still looks as new as the day it was done and does eliminate the
sometimes ugly discoloration that aluminum plate will undergo after exposure
to some environments.  So I am happy with the results of Nickel plating
aluminum.

Next Year I expect to see you at Sun & Fun with Aircraft.  After all, Finn
has long enough basked in the attention  of having the only rotary powered
RV-3 - I presume that is why his aircraft is frequently the center of
attention {:>)
