Long before Colorado legalized pot, I installed the slab/T-tail on my Zuni
upsidedown once (similar to LS, but with two pins)...then wondered why I had
difficulty getting the two indicating-safety-ing pins to indicate all was
well. Turned out, it *could* be gently forced aft until the indicating pins
snapped into the "safetied" position...but to do so definitely required
noticeable installation/aft force, when proper installation was essentially
force-free. Also, the fore and aft stick motion would've been restricted due
to the cross-sectional shape of the horizontal stab's vertical stab cutout.
Still, it was a thought-provoking experience...
