Anybody have photos of such a collar? Or able to give a good
description?


Pretty sure there's one in Tony Bengelis' books. But you just take a
collet and slide it over the tube and then experiment by moving it
back
and forth until your ASI is doing what you think is right.

I tried that on my Johnson Rocket and got it to indicate 200 MPH in
level flight! Of course, it stalled at 100 instead of 60. ;)

All it is is an O-ring or something similar placed ahead of the static
pickup in the pitot/static system. This works only on planes that have
a
combined pitot/static head, not on those that have the flush-mounted
static port on the side f the fuselage.



Ah, OK, you mean the ones with two tubes, right?
