Fox,
Here's a pic that ChrisSpad showed me a while ago. You just run a piece of music wire up through the elevator hinge, and rudder hinge, bend it 90* and stick the bent end through the flutes in the rudder. It may work better if it goes through the rudder between the control horn base and the control horn. The bottom is just a tail skid, but you can put a 90* bend in the bottom and put a wheel on, then a wheel collar and a piece of fuel tubing CA'd to the wire to lock everything on. This works like a charm and has survived literally hundreds of take offs and landings in a grass cow pasture (beware of the moo-moo poo-poo![X(][:'(]
).
Blue skies,
DL
