Fred,
I have an email from Andy Draper, dated may, 2002, which could be
out of date by now. This states:
The correct force that the friction damper should resist is 5kg
+0/-1kg at 90 degrees to the long arm (the one that the servo attaches
to)
At the time I thought this was a hell of a load and I settled for
the lower end of the range.
Ahh that was Andy!
As I wrote a fish scale did the task fine.
I used 4,5 kg.

All,
Before bonding on the top, I want to be certain that the Trim Damper
Assembly is properly adjusted, particularly w/ respect to the amount
of friction when it moves in the slot in TS01. As far as I can tell,
the Build Manual does not address this question, yet it would appear
to be key to having the pitch control system function properly without
burning up the pitch trim motor. I can't seem to get my mind around
the function of this seemingly elaborate confusion of spring, tube,
thru bolt, and nuts of various sizes...it's complexity suggests that,
when properly adjusted, it performs a critical function.
I reference Fig. 2, p. 19-2, and Step 4 & Fig. 6 on p. 19-4.
Can anyone please enlighten me on what proper adjustment would be?
Thanks in advance,
Fred
