Sabrina, were your cables pre-loaded and set to the correct tension originally,
or did you just "eyeball....feel" the tension? Interesting that the cables
lost that much tension in just a short time!!! Thanks.

It is possible to flex the skin between the aileron hinge and the aileron ribs.
The 650 adds aileron gussets, I am told.

"b) Inspect both ailerons for any type of deformation of the skins at the piano
hinge area and root rib area."

They were set with identical model cable gauges. The only problem is that over
the telephone in November of 2007, and there may have been a lot of static on
the line, what was heard from Zenith was ALL cables: 25 +/- 5, with the caveat:
light side on the rudder, heavy side on the elevator. There was another
conversation where 30 +/- 5 was mentioned but the voice was not recognized and
they made no differentiation between any particular control surface.
So too, this time an IA did it.
>From what I recall, and from what I can decipher from my notes at this time, this
is what they were set at originally in November of 2007:
right aileron set to 25 found to be 25.....OK
left aileron set to 25 found to be 25.......OK
balance cable set to 25 found at 20........it runs through more nylon
up elevator set at 30 found at 35...........elevator neutralized this time
down elevator set at 30 found at 35......elevator neutralized this time
left rudder set to 20 found at 27............different lift methods used
right rudder set to 20 found at 27..........different lift methods used

Nice looking machine in the opening post. Thought crossed my mind that if the
aircraft is left bare for aesthetics-might be an idea to PAINT those portions
, with aluminum colored paint......to maintain the look , and add corrosion protection.
Two good sources on aircraft corrosion
Death By Corrosion (http://www.amtonline.com/publication/article.jsp?pubId=1&id=1438&pageNum=1)
and
Fairly long, but worth-reading FAA pdf (http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/A7FFC0F8B6216A43862569B5005081ED?OpenDocument&Highlight=corrosion%20control)
Bare aluminum good products:
LPS3 (http://www.marvgolden.com/aircraft-supply/lps3.htm)
or
Dinol AV5 (http://www.ingentaconnect.com/content/maik/prom/2001/00000037/00000001/00299233?crawler=true)
Another way they're starting to experiment with more-to protect ( in particular
unpainted ) aircraft-sacrificial anodes. Although they're putting small sacrificial
anodes ( a few ounces ) in the aircraft body ( although this wouldn't work
in military aircraft ( built of metals in the same galvanic number as the
anode=no current flow) I wonder why a 12 pound magnesium sacrificial anode ,
in a five gallon metal pail of water, which is coppered to ground, and also having
one light wire from anode to an all aluminum aircraft,wouldn't also induce
a 5 millivolt current flow-blocking the aluminum corrosion, and inducing the
sacrificial anode to corrode instead ( while the aircraft is tethered ) -just
like I do with buried water valves.....
