The youngest of these ships are around 33 years old, only 129 of them
were built (and a few don't exist anymore). So, let's face it - we fly a
rare (yet tremendously beautiful) ship....

Hmmm, I would hardly call any plastic ships built in numbers over one
hundred "rare", although I completely agree the Kestrel IS
tremendously beautiful (at least the 17m Glasflugal version with the
removable rear canopy; I never acquired a taste for Slingsby's 19m
wing or the hinged canopy, although I'm sure the latter is at least
convenient...).

I can't see a reason why flt computer/recorder manufactures/designers
left out the Kestrel, other than perhaps it is neither at home in Std/
15m, 18m, Club or World Class. Although it can be flown in the Open
Class, it is really outclassed there so really only finds itself able
to effectively compete in US Sports Class in addition to pleasure and
record flying, but numberwise, certainly enough were manufactured to
justify stock polars on the computers and recorders were there not
other reasons. YO Dave, why no Kestrel polar on SN10?
