For those out there that implemented mod 70 (tailplane mass-balance arm
replacement) and hacked out the cables, how is it going? While flying
through steep banks or turbulence, can you feel (through the stick) the
mass-balance weights thumping up against the guide strips? Maybe it can be
felt as a slight resistance to fore/aft stick movement? Due to the very
small clearance between the weights and the strips, and the tendency for the
arm to wiggle laterally, this is sure to be happening.

I built the 'H' support with precision, as if going to use of the guide
strips, but am expecting to switch over to the cables if the tufnol method
did not perfectly satisfy me in the end. Part of the satisfaction is in how
it works in flight. I cannot find anyone weighing in on this yet..

The turnbuckles and nicopress clamps have been sitting in a box gathering
dust, and they would like to know when they are to do their part.
