Does anybody have a clue where I could get a "Whiz Wheel" for a

faith in the reliability of their electronic glide computers. Last
week my computer lost its 3-D GPS fix and I was forced to use my
wits...not a very useful tool. I've contacted all the usual suspects
in the US and asked the British Gliding Association for ideas. Whiz
Wheels seemed to have gone the way of my wing-mate the Dodo bird. TIA

All you need for a home made one is time, patience, a copy of the polar and
a computer. If (like me) you need the geriatric version, the rotating bit
makes an ideal use for one of those giveaway "sign up to AOL" CDs.
