I have used my pool vaccum pole. It adjust out to 35 feet, taped a large sponge to the end of it. It allowed me to jar the plane loose from the tree. Once the plane came free from the tree, I dropped the vaccum pole and was able to even catch the plane before it hit the ground. It was a perfect soft 3 point landing in the tree, so there was no damage to the plane. At work a friend of mine got a bipe stuck in a tree. Limbs were between the wings, he eventually got it down with tennis balls. He took and needle and threaded fishing line into the tennis balls, and just kept throwing them until the ball and the fishing line wrapped around the plane enough to allow him to dislodge the plane.
