Would require water to land on and a boat for retrieval. Lifejackets, oars, motors, water skis, assistant to drive while skiing. WOW, starting to look expensive. If you have access to a rowboat, go for it. Wrap rx and battery in plastic bag to keep dry. Have marvel mystery oil/automatic trans fluid in 50/50 mix for flushing water out of motor to avoid rust. May want to rinse in denatured alcohol first to clean.
I'm sure there are others here with actual float experience that can help. I like my planes dry.[
