One thing I think would work is pitot tubes on each wing tip connected
to a Winter type variometer with the vario rotated so the needle
pointed up. Air would flow from the faster wing tip to the slower one
through the vario which would show rate of turn. It's the only "non-
gyro" rate of turn instrument I can think of.

Yes, I see that. Reminds me that some folk have played with a GPS on
each wingtip and some decode software - not very fast on its feet
though, I don't think - even at 5 frames a second...
