RE: any simple tie down methods
An inexpensive dog leash and a cheap screwdriver work well. Get a leash with a small metal ring on one end and a holding loop on the other. Stand behind the plane. Stick the screwdriver through the metal ring and into the ground. Take the end with the holding loop, pass it UNDER one side of the horizontal stabilizer, up over the top of the fuse directly in front of the fin, then back UNDER the other half of the horizontal stabilizer. Then slip the holding loop over the screwdriver. Be sure to roll the plane forward a little to take up slack before you start the engine.
