I installed an old door hinge in the hangar floor with Tap-cons ( so it lays flat when not in use (toe stubber!)). Drilled an oversized hole in the leaf that flips up.
Flip up when needed and hook a small block and tackle to it and the tail tie down. I actually use a couple pulleys and a cleat thing I saw at Home Depot. Works great. If you have a helper, you can just have them push the tail down while you hook it with a short rope or chain.
