Someone asked about where to buy titanium rod. You can get it from www.mcmaster.com. Look for the Ti-6Al-4V titanium rod and better sit down before you check the price.

Have to say again that this is exactly the right stuff for tie-down stakes: light and strong.

Default And the ropes -

A couple folks asked about tie-down ropes.

Avoid climbing ropes. They are designed to be stretchy. They absorb the energy of a fall by elastic strain energy, and this is exactly what you'd like to avoid with tie-down ropes.

Using Regatta Braid, I'd recommend 5/16" but 1/4" would probably suffice. I use 5/16" on my Cessna 180. http://tinyurl.com/c2xpwqg

Using a fancier line like Endura Braid, http://www.apsltd.com/p-22155-endura-braid-5mm-316.aspx, I'd be happy with 3/16".

I'm fond of Samson's Warpspeed, http://tinyurl.com/ckxswmv, and if you can find 3/16" that would do. The link is for 1/4" which is overkill. It's a nicer line to your hands than Endura Braid.

Default Climbing ropes

Actually there are two types of climbing ropes, static & dynamic. Static lines don't stretch.

"I always have a good angle between
the tie-down ring and the ring on the wing
and wish the tie-down 'testers' would have
also tested the tiedowns at an angle.
I'm not sure their results would apply in a
real world situation."

They don't say what material the stakes are made of but, since they claim zinc coating, I would guess steel. The 8lb kit weight also supports that.

Default Really light stakes

The almost ultimate light stakes--but at 6" long, seem a bit short...

The leg brackets on the "Claw" tend to break off if you have the ropes at an angle. Saw many broken ones after the Sun 'n Fun storm. When using the "Claw", I tie straight down.
