Tony,
As stated by others it is far easier, with no other problems as a result, to shorten the plastic clevis so the total length is about 1/8 inch shorter. Normally 2- 3 mm is OK 1/8 inch .125 is the max I have ever trimmed.
Leave the trim rod alone then and you'll be fine.
Regards,
Bud Yerly

Tony
long time ago but I shortened the plastic a couple of mm.
Maybe the simple way would be to assemble the whole thing without fixing
the servo to the bulkhead, then work out where it needs to go without
causing the fouling

Hi Craig,If you shorten the link rod, don’t you change the geometry of the tab displacement? I know Bob Harrison did a similar thing, and he hasn’t had any problems with the consequence. I will have to take a closer look, as it is an intricate mechanism, and I take my hat off to Ivan and co for designing it. How you do that makes me envious. I might get another link rod and experiment. Scott from Ray Allen is very helpful, so if I stuff it up I’m sure he will come to the rescue
Thanks for replying.

[quote]Tony, have a look at the link rod between the servo and the bell crank
I had a long hard look at it and ended up shortening that link rod about 2mm, trimming the plastic will fix the issue, mine only needed about 2mm total to gain
The required clearance, I filed a bit off each one and problem solved, prior to that 2mm it would foul
And try to push the servo up at full travel
Hope this helps, it may be another way to attack the problem

Gidday,
Well, it seems my Trim Tab Link Rod, TS05 is conflicting with my plastic forks of the servo, like many others. I think I have to eat humble pie here. The issue is that the vertical of the two rivets that hold the insert AN490 HT8P in position, its head is the culprit. It looks like to me the easiest fix is to take a little of the fork excess plastic away, but there isn’t much, and any finer adjustment needs to be made by removing the offending rivet, and repositioning it. Thats my current plan, and to that end I’d like to ask what the length of the insert is that is within my T bar tube. I am thinking of removing the offending rivet and repositioning 45 degrees offset. I would like to double the spacing that exists between the current rivets, in side elevation, for the placement of the next one, so I have double the metal since I have half the offset, as the holes from the removed rivet will have created a wall weakness. Still, there shouldn’t be a ridiculous amount of load on these, and the second one is probably more of a secondary means of attachment, aviation double check anyway.
If anyone has not constructed the T bar, can I please ask for the insert length? I will ask Europa if the list is unable to help. Thanks.
Regards
Tony Renshaw
