 I have a question regarding the ew logger: the place it has it
listed up for sale differentiates between the engine version and a
pure glider version. Mine will be used mostly in the glider, but I'd
like have the ability to use it in a motorized glider as well, for

Hi Race Fans
The proposed contest rules changes for 2009 are available at the SSA
web site  under Sailplane Racing/Rules& Process. Due to a long time in

Needing a replacment, my transponder shop told me that above 15k' the
FAR's require a 250 watt transponder (125w below 15k').

sure a disc brake is the way to go. The cost for a suitable drum brake
is about 2x what a disc brake from Grove or Matco costs, Azuza makes
drum brakes, but they don't seem robust enough for my needs.

Having done most of my flying at lower altitudes, I have wondered
about the contradicton between my unscientific observations when
flying at high altitude and what I would expect from my somewhat
limited knowledge of physics and aerodymanics.  I certainly believe

My 3970 that runs Winpilot has died and I need to replace it. I have a 3900
cradle fitted to the cockpit. What can you guys recommend that will run
Winpilot?
I believe the 5500 series IPAQ will fit in the same cradle. Can anyone

Interesting subject needs new thread.
It strikes me that a glider designed to soar in weak thermals is well
off its design point when running fast in a wave XC or, for that

Caesar Creek Soaring Club is investigating the possibility of winch
launching on our field. As expected there are very polarized opinions
on the merits, value, and safety of winch launching. I would
appreciate any rational inputs on the merits of winching or reference

I mentioned in another thread that I had been experiencing incorrect
mode C reports when the airplane was cold.  Since a few people offered
suggestions, I'm following up with a report.
