[RCSE] Some hard facts of launch

Message text written by Paul Clark:

"Does anyone know if this actually happens - do you get a little
more launch height when you throw your sailplane into rising air?"

Way yes.

Also...we have been measuring launch heights with great precision
utilizing a Laser range-finder... and  some may be suprised with the
results.

With a 7-9 mph wind JOE WURTS and MARK NAVARRE were throwing
VERY consistant 29-32 meter launches...no sweat.
Joe was throwing his ancient 6063 Encore and Mark was throwing an old
own-design (wizard rip-off) with the wing tips cut off (that zona saw
again).
and yes Joe was out-launching Mark by a meter or so.

I'm guessing that not everyone throws that high, and today we lasered some
ordinary mortals, and sure enough thier launches were more like 15-21
meters
in the same conditions.

Now you have a goal, and some HARD NUMBERS.   Go for it!

John,
I resemble that remark!

Tom

PS  I was one of the mortals launching at ~19 meters today (which was
actually higher than my precision-calibrated eyeballs were guessing prior to
this).  Hard number comparisons are nice to gauge against.
