While I am sure that your battery is dead by now, taking your transmitter on the hike into the swamp can help you. I lost one in the forest to the south of our field. I hiked into the forest and spent 2 hours looking down. I hiked back out and got my transmitter and went back in. I got into the general area that I figured it had gone down in and by operating the sticks I could hear the plane. Did I feel stupid for having spent so many hours looking down as the plane was parked perfectly in the top of a tree. Once we got her down, she had a few holes in the covering and one broken wing rib. Had her repaired and ready for flight in about an hour. I hope that you can find her. Hopefully Mikes camera can help locate it. Good Luck, Dave
