Graham,
You are right. I forgot the effect of T bar weight too. I still believe the
corresponding
error is less than the error caused by the slightest bearing friction.
The weight to be added to accurately compensate for the missing T-bar error
could be easily calculated. As the T-bar cannot be removed from a completed
aircraft, could any one in the early building stage provide me with the weight
and CG of the trim tab T-bar, ?

I forgot the weight of the trim tab control arm does affect tailplane
balance, so balancing outside the fuselage is not quite so simple.
