Although my RG has not yet flown, I installed guides as an ounce of
prevention. The side load requirement will vary with the pivot drag, as you
suggest. Trouble is, in the real world, not all pivots will always be adjusted
properly. And there is at least one additional failure mode: a shimmying

Although extremely rare, there are probably other ways the wheel could be
turned during flight. We've identified two, but there could be more. The point
is, IF the nosewheel ever becomes turned while retracted, there is simply no
way the pilot can get the nose gear to lower.

I have not heard of this. Can you give details?
