Following the exercising of the servo movement, it was obvious that some tweaks were necessary.
The first was toenlarge the cutout where the servo rod exists from the elevator, so I marked it out and then ground the necessary material away using the Dremel - a very handy tool indeed.
There are a couple of other things to be done yet, too - but I'll leave thos euntil the next session. The fist is to gently band the lower lipof the trim tab skin up, to avoid fouling on the elevator aft spar. It.s not much of a foul - probably less than 1/4 of a mm - so anly a gentle tweak should be necessary
The other item to address is that at full servo arm travel the clevis pin attaching the rod to the servo arm catches slightly on the servo attachment plate cutout. Whilst expanding the cutout hole would fix this, I think that putting a very slight bend in the servo rod (which the plans allows to be acceptable) might also achieve the same aim, and would be more elegant. I think I'll sleep on this, and consider the feasibility and options
