First remove all real valuable equipment and replace with expendable servo's, rx, bat ect then tape and glue the remains as close to original as possible regular ole shelf paper will work to cover large areas. tape a rock or sock full of sand to the motor mount to maintain cg. Then have another pilot tow it up as high as you can get it release it then try to plant it straight up and down into a garbage can placed on the other side of the runway. This can also be a fun-fly event.
But make sure you have a video camera handy so the rest of us can enjoy.
Some times you have to save up parts from two or three different crashes to get a flyable carcass.
