Brett65,
A popular ground restraint at our field is a heavy bag of lead or steel.
Attached to it is 2 leather or nylon cords that go up under the
the stabs to the top of the fuse and are tied with a quick release knot.
When you are ready to fly untie the cords and taxi to the runway and take off.
The reason these are so well liked is it prevents the need to pick up a plane with a spinning prop.
You'll have to experiment a little to make sure you've got enough weight.
I think they weigh around 10 pounds.
Good Luck,
