Perhaps somebody will enjoy this. I re-did the floats. Now it lands smooth. Take off is also smooth. This is version 1.1. Did not install v1.2 yet. As you can see it also goes in reverse when on water (depending on wind direction, etc). I FINALLY have Mallard (hehe). Link: https://youtu.be/P7M41f9Oxjo .
