Dick Johnson's wing flattening jig?
JJ- You're not spillin' the beans on th Mark IV version with the 4th
order reflex compensation are you? I thought we agreed to keep it to
ourselves till 2015.
Are you selling out on me?

At the time of his death, Dick Johnson was also working on a ground-
loop prevent'er and I have his concept drawings. The heart of the
system is a gyro that instantly detects lateral motion while on the
ground. The unit is armed via an oleo-strut micro switch and directs
high pressure air to the opposite wing (ground-loop detected to left =
air directed to right wing). A 2 inch plastic sleeve is mounted inside
both wings with a 10 pound sliding slug that will instantly fly from
the root rib to the wing tip just as soon as the gyro detects a ground-
loop developing. I believe the concept to be sound and I am presently
working on a method of stopping the slug when it reaches the wing tip.
Stat tuned,
JJ
