Not many "ultralight gliders" in the US until they built the

There's still more Carbon Dragons than SparrowHawks... * nearly 2/1
IIRC (might not all be in US, hmm), but even added together it's still
not many... *Gary Osaba knows a great deal about the fine lines of the

set a respectable one of TX in a too and would know the nitty gritties

His Silent was 281lbs empty for the flight, within D/U *limits. If it
were the motorglider version, it would have been 140lbs heavier and I
think out of weight for the category. You should be able to
extrapolate whether Leah and her Cherokee are too fat for this
category or not. If they are over however, I recommend different
verbiage to convey this point

not to mention there are a few woodstocks out there.

Good point Paul, I'll check in with Gary and Leo. I had read Leo's
flight report in Soaring, what a story.- Hide quoted text -

the entry for the Silent 2 pure glider on the Sailplane Directory
says:

---
Several World records have been set with the Silent 2 in the FAI Class-
DU. A basic airframe combined with reasonable pilot weight will
generally result in a take-off weight under the 220kg (485 lbs)
maximum allowable required for the FAI's DU Class.

and the maximum allowed weight (mass) is shown as 245 kg. This seems
to indicate that the mass at takeoff is all that matters.
