I recently purchased a Phantom and I'm curious if anyone has tried (or heard of someone trying) to attach the unit to a cable guideline. My goal would be to capture a long distance "follow cam" of a downhill mtn biker thru tight trees in a straight line. If I can somehow rig a guide to the top of the phantom (think a hollow tube) and then attach that to a rope or cable it would keep the phantom from hitting a tree and allowing it to get some pretty cool high speed shots. Thanks!
