If you want to create your own ground restraint to hold your airplane back when starting it, you can make a simple Y holder out of 1/2" coper water pipe tubing.
I use a long plug for the bottom, that way it is easier to push into the dirt. 1 T joint, and 2 90 degree elbo. Then cover the parts that will be against the airplane with 1/2" pipe foam insulation. and zip tie it down close to the corners so it does not hit the plane.
