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 che
cklist: 
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 cyc
ling the trim motor through its range whilst holding the stick fully back, a
nd listening for any labouring. 

In my aircraft I did have the problem, as I also didn't know about shortenin
g 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 v
ery easy task to undertake.  As Bud said there is not a big amount to be rem
oved from the clevis/fork ends, just enought to ensure you get no binding be
tween the belcrank and the TS05 push rod when tailplane and trim tab is in t
he configuration as described above. 

Kind regards
Donald(G-PUPY) (Nearly flying, awaiting paperwork from LAA to conduct flight
 testing)

 the only thing better is to remove it from one and check the operational cl
