Hello Alex,
My tailplane is the same. This is typical and does not affect the flying
quality or characteristics of the plane. If I recall correctly the lower
fuselage has a slight twist in it. I would suggest leaving as is.
If you attempt to relocate the bushings in an effort to level the torque tube
you will change the alignment of the tailplane with the mating profile molded
into the sides of the fuselage. This mismatch between the fuselage and
tailplane will be very noticeable. Hence, the recommendation to leave as is.
Regarding the modification to tailplane mass balance arm. Again, if I recall
correctly the TP18C Adjuster Body was adjusted to the extreme end of TP18B End
Fitting. This created a large bending moment at root end of TP18C resulting in
its failure. Europa issued mod 70 with a redesigned mass balance arm and
constraint of the TP19 Weights.
The failure was attributed to a number of landing mishaps. Regardless, the
original design did not adequately keep the weights from swinging side to side
as there was no means to tighten or adjust the lateral restraining cables.
Additionally, it was deemed that heavier tube and a stronger adjusting
mechanism were warranted.
Lastly, I noted that you have kit number 529. Most likely your kit has the
redesigned TP18 arm. Per the documentation in Mod 70, kits up to number 194
were affected (those delivered prior to February 2005). So, maybe this isn’t
an issue for you.
