MM,
This would have been very useful a couple years ago when Tom Morris had a spell while flying his electric Carvel at the Palmetto Contest. Luckily, he was able to get someone into the circle to take the ship while he got down. Having the ability to shut it off wound have allowed cleaner access to the circle to attend to Tom. Fortunately, the ship was able to stay out of the way of the paramedics and didn't have to be crashed.
I know we have to use the 2.4hz radio per the general rules section but it seems that for a simple OFF only, if there were a better way we could get something done. Tim, Ken?
Best, DennisT
