Last year when we were at Sun N Fun it was really windy both Sunday
morning and Friday evening. We made sure our planes were tied down
snugly, then looked at the other planes around us. Quite a few had the
doggy tie downs, and several, close by, had them only screwed into the
ground about 1/2 turn! 95% of the tie down was out of the ground! How
dumb can some people be?

I agree with Ed, the doggie spiral do not work well at EAA. I belong
to EAA Chapter 444, we make our own tie downs and sell them on the
north end during EAA. I can not tell you how many times we help remove
broken doggie ties from the ground with a pipe wrench, or how many we
find when one brakes and we just find them in the ground, not good for
tires! We sell them for $20 or rent for $10. I plan on being at Wausau
for the National event. I would be happy to bring some with me if I
knew how many! You do need a hammer to put them in the ground, but
they work. You get three ties downs with rope for each, We sell about
150 - 200 per EAA event. Also, it's a county law that all planes must
be tried down at EAA.

Rick,
Those dog tie down connector loops look to be about the same
thickness of metal as the rope-loops on the spiral doggie-ties
that break off so easily. I trust you aren't tying your rope to
the loops that came with the dome tie-out stake.
The pull on the tie-down rope has to be greater than 500 lb. to
lift the plane and might well, in a good micro-gust, be way higher.
I've seen some of the spiral doggie ties break both at the
rope-loop and at the main stem. I certainly wouldn't willingly
use one of those. The dome tie-out stake you advocate looks like
the spike might be thicker, at least.
Since they are so cheap, you might want to test three or four of
them to see how they stand up to 500-1,500 lb. pulls, both in the
strength of the metal and their ability to resist pull-out in
various dirt types. I'd be interested in your results.
I'm inclined to go with the claw. It looks more substantial to me.
Ed

Several people asked for more info on this.... I found a site on
line that sells them - with a picture. I got mine cheaper at
wal-mart. I use the swivel hook in light winds and tie under the
flange long-term parking.
I got the leatther gym bag in a flea-market type discount store
for 2-3 bucks.

It's an option!
