In the RC world, many people use a spare radio channel to release things like parachutes,etc. I know that the vision plus does not have a spare radio channel, but I have the following need. It can take a few hours for a high-angle rescue team to arrive at a hiker or climber stuck on a ledge, and I want a way to fly a phantom to the subject, and drop lightweight things, like insulin, medications, SAM Splint,etc. It is too dangerous to tow a line and expect the subject to remove it, we risk losing the entire craft if it tangles. Any ideas would be appreciated. It can be: 1. a separate receiver, which does not interfere with the Phantom frequencies 2. some ingenious way of doing a release when you make 2 clockwise 360 degree turn-arounds,etc. 3. a line that disengages upon x lbs. of pull. 4. anything else you can think of. Thanks.
