Standalone Flight Recorders for Club Use

The Tucson Soaring Club recently purchased two of the EW units and are
very impressed with them. I haven't personally flown with one yet but
they seem to be ideal for club environments, and set the standard for
ease of use.

We have been flying with the microRecorder for a few flights now and
have these comments;

1) The antenna needs a good clear view of the sky. I put the antenna
under my turtledeck in my fiberglass glider and found that I missed a
few GPS fixes during the flight. Nothing major and wouldn't have
invalidated the flight. No problems when I mounted the antenna to the
canopy. This problem did not occur on the Cambridge-302A version so I
can only imagine that the EW GPS receiver isn't quite as sensitive as
the Cambridge.

2) I was using the defaults for the configuration. After two flights
separated by 20-30 mins I found that there was only one log file
(which contained both flights). I am unsure if this could be a
problem for multiple flights with different pilots. Looking into this
I found that there was a 90 min auto-off timer. I reset this to 10
mins.

Otherwise the unit is working out well.

I would concur with John. I have the antenna on top of the EWMR and
that sits behind my head (under fiberglass) in my 19. Has worked just
fine there so far. One thing about the auto-off timer though. I was
down at Perry at the XC Camp. We were gridded and I was near the
back. I turned the unit on so that I wouldn't forget to do it once
strapped in. However, I sat in the grid for longer than 30 minutes
(which is the default value) and the unit shutoff (as it should). I
didn't notice and when I came back, no log file. Luckily I had the
one from SoarPilot so all was right with the world. :-) Just
something to keep in mind.

Later!

John,
I sent an email direct to you but my guess is that it got lost as
spam. Do you have a source for those nify lexan boxes you have for
the EWMR on your webpage? Our club is getting one as well and that
would be a nice thing to have. The surgical tubing idea is VERY good
as well.

Thanks for the info.

Hi John,

I don't recommend setting the auto-off timer to 10 minutes. It may turn-off
while you are waiting for an aerotow. I recommend a much longer time.
