RE: recovery craft
Various ways to retrieve a plane
Photo 1 was grabbed from an earlier post here on RCU. It works as long as you have an intact plane. A lapful of sharp fragments might complicate things.
Photo2 is the way it's supposed to be: Taxi up to the beach and a helpful soul grabs your plane for you.
Photo 3 was an experiment with r/c boat retrieval.....not particularly successful.
Photo 4 is the 100% reliable electric-powered man-carying boat. 2-man crew lets one grab the plane while one concentrates on driving.
