We are not falling out so far as I know, just contributing to a discussion.
Agreed

What puzzles me in all this discussion is though, I have never experienced the trim change and possible elevator anomalies due to boom/wing rod fit.

Neither have I, but lots of people have, so can not be discounted, have a look on the " Elan has arrived" thread

The boom wing rods on my XL are so floppy you can lift the back end nearly two inches, the aircraft performs flawlessly, no trim change whatsoever and no woolly feel to the down elevator?

Are you saying that your tailplane can move two inches out of alignement i.e. change incidence and you don't notice a difference?

This condition I believe is either jet wash under the tail plane sucking it down (this was the problem with the Bobcat) or the wing section, which is not symmetrical behaving differently during sharp negative push. Either way I cannot see this being due to elevator power or boom movement.

If it is jet wash it should have an effect in straight and level flight by a noticable change from low too high power, as I said some have experienced this, but the majority have not.

jmo.

Also just my opinion.
