Aviation content- Check. Informative - Check. Breaking shit- Check. This is great Rich! I second the Plane Perfect products. I got my bottle of eyes outside based on your recommendation. Thanks for that too.
Great video. For those heading to AirVenture if a storm approaches (😂 we know one will), another safe precaution if you have a tail dragger, is adding a 4th tie down directly out the bottom of the cowl. My friend Joe Champagne showed me the trick in Vintage camping with the Pacer & Luscombe.
Great video Rich! One caution on the cable type anchors...I had a few of these installed to keep the kid's swingset from rocking. I moved the swingset yesterday, and every one of those cables was rusted in two after about five years in the ground. Maybe I bought cheap ones and stainless ones are available? I've had good luck with screw-type anchors in our black soil (the kind with a screw welded to a shaft, not a corkscrew dog tie down. They do take quite an effort to install though.
Good note on the cables. I don't know of anyone selling a stainless solution, but the company that makes duckbills will sell you just the anchor portion and you could attach your own stainless for a permanent installation like that. Thanks for sharing your experience.
In 2012 I had 3 pieces of #5 rebar welded with a T at the top of a 2 foot long length and then painted to prevent rusting. Using a 5 lb small sledge hammer and hammered it at 90 degrees to the direction of the tie down rope from the aircraft. All the way to the ground with the T just showing in the grass. Tension of pull is 90 degrees to the direction of it being hammered in. Works great, but I have to bring the small sledge hammer with me. Pulling the stake along its direction of installation when taking them out is relatively easy. Never had any problem with it for all my Oshkosh trips from 2013 to 2022. The secret is the rebar protrusions. They work in soil the same way they work in concrete.
I'll test anything people want to hook me up with. Happy to test anything out there now that I've figured out how to do so. Even willing to test homebuilt solutions if people want to get some numbers for their personal contraptions.
There’s also the one that EAA published plans. That would be interesting to see, since any decent fabricator could make a set pretty easily at much less than the Claw costs.
TLDR; Longer anchors, planted at 90 degrees to pull. The angle of the pull relative to the anchor, multiplied by anchor length. If you drive a stake straight down, it takes the least amount of force to pull it straight out. Change the force to 90 degrees, and the force to pull it out is a factor of the lever arm. The longer the lever arm, the more force. Also, if the force starts to generate soil movement, the anchor is failing. continued movement will weaken the anchors and they will eventually fail. The best anchors you tried had the longest anchors, with the best lever moment.
Rich, long overdue and a great topic we can use...next to food! To go along with the tie down base, equally important are the tie down ropes or straps. Keep up the great job
Nice part about the EAA Tiedowns..... the chapter will pop your EAA purchased tie downs in the ground for you every year for no additional cost. No need to bring you own hammer to install. The North 40 is littered with rocks from fill especially north of 09/27. Multiple marriages have been saved by having someone else install your tie downs after flying the OSH approach, being overheated, and having to use the bathroom.
Not saying the dog stakes are great but turn it 180º from your video example and it will perform better than posted. Also what if you fastened it to the ring, not the handle. The handle was never designed for fastening.
Great testing! If you do another round try out the Ground Grabbas, they are a giant screw designed to hold into many types of soil. These are what I’m bringing to Oshkosh: www.groundgrabba.com/

Thanks for this. This is the first time I’ve seen a comparison of various solutions. Very relevant information!
Very welcome!

That plane perfect kit is awesome, I will be picking one up for sure!

I'll be picking up some of the Plane Perfect to try and get C-FMVU polished up for the show.
Good part 1. Can't wait for the next part where you test the Claw and StormForce.

Great Video Rich! Glad to another video!
Glad you enjoyed it!

The shipwreck search I mention at the end of this one has camping and food. Stay tuned. :-)

Great information! And thanks for sending a kit so we could include it in the video.
So much for my dog stake idea. Great video!! Thanks @Just Plane Silly for the link!
Interesting test. Thanks.
very good!
Thanks!
Here, Here for plane perfect!

If the Short allowed comments I would have suggested watching this video.

If you have a contact there, I'd be happy to have them send me a set for testing. :-)
