Hi Tony
I believe the fouling is between the bell crank and the TS05 push rod.
The following is a copy of a check to be undertaken as part of the final checklist:
Check that trim bellcrank does not contact TS05 push-rod when fully forward (tab full down) and tailplane is trailing edge up. This can be checked by cycling the trim motor through its range whilst holding the stick fully back, and listening for any labouring.
In my aircraft I did have the problem, as I also didn't know about shortening the clevis/fork ends. I therefore had to do the remedial work with the top on and was working single handed through the fuselage access holes. Not a very easy task to undertake. As Bud said there is not a big amount to be removed from the clevis/fork ends, just enought to ensure you get no binding between the belcrank and the TS05 push rod when tailplane and trim tab is in the configuration as described above.
Kind regards

[quote]Hi Bud,
Could you please elaborate where the fouling is more specifically? I appreciate knowing this, so I am thankful Bob brought it up. I have the top still off so its ideal I overcome these issues now.

You are right on the money. Every aircraft I have built needed about 1/8 off each clevis on the pitch mechanism to allow the trim bar to clear at full elevator and trim travel. As for interpreting the English Language.... No comment.
