What do I use to secure a bungie in a super flat field with nothing around?

My small hi-start has something that looks like an 8 inch spike, probably a good size tent peg would work too.

Perhaps for a small one with a light pull. I've never tried a heavy duty one but I would think there is a strong pull on it, you would hate to have a failure at that point.

You want to be careful there - imagine what ever you use coming at you at full pull ...
I always use one of these things, no idea what they're called in english, but I figure every outdoor shop carries them.

Works fine for my F3B bungee pulling like 40 pounds ...

You can buy the screw-in dog tether from a pet shop.

Be careful...

Any peg needs to go deep. If I recall my local club regulation correctly for winch turn arounds, each turnaround needs two or more pegs each of 40 cm (16 inches) length that are as thick as a finger. They are driven in at angle to where the pull comes from using a heavy mallet. With a bungee/hi-start the pull is not as strong as a winch turnaround. I use a corks screw peg that came with my hi-start. It goes in about 30 cm (12 inches) and has a 5 cm (2 inch) diameter to the screw. The corkscrew is great. No hammer/mallet required. Just turn it in.

Make sure that no one is near the peg in the ground when you start to pull back!

The screw in dog tether type item above works very well. You can screw it in deep rather easily and you can unscrew it easily at the end of the day. Pulling directly up on the stake does not pull the item out of the ground.

I have used a plastic tent stake in the past and have had it pulled out of the ground after the plane was at a good altitude. The 100 foot heavy duty rubber looked like a constantly changing black line moving higher and higher, totally taking my concentration away from the plane I was flying. When I realized what I was looking at (the rubber was now about 200 to 300 feet up in the air) I began to worry about where it would hit the ground!! After that I made sure the stake was placed deep and at a good angle into the ground. On wet days or with loose soil the stake had to be placed into the soil as deep as possible. For these reasons, the dog tether shown above is superior to the tent stake.

What do you mean by bungie? Here, the term bungie usually refers to what slope flyers use - a length of fat rubber tube with little or no string to launch slope planes at extreme speed.
Are you talking about a high start?

Usually something made of iron/steel 12"long or greater works fine... I put mine in at approx 25 degree angle... the exposed tip leaning away from the pull. (Rod lenght mostly depends on how solid the ground your staking in is.)

home depot has concrete spikes. They are anywhere from 12 to 24 inches ( or maybe more,,,dunno).

they have hole drilled through them os it is easy to put big washers in with cotter pins.

works great !! Very stable, and the pins make securing your bungee ( which I use snap rings from keychains for the bungee ends) easy as pie.

You can find these stakes by the rebar ( at least at our home depot you can).

Depends on the type of ground.

If its soft sand, you need a sand anchor.. looks like a post hole digger for telephone poles sort of.. helical plate blade that you twist into the sand (so that the thing has to pull 50 or 100 lbs of sand to move the anchor)

If its rich black farm dirt.. I like the corkscrew dog chain anchors. The soil of this class is firmer than the sand.. but not firm enough I trust a peg.

If its a clay based soil I use a 3/8 inch dia 12 inch "spike" nail.

If you can't drive that spike in.. its rock. You need to drive your car out and use the trailer hitch as the anchor.
