I’m glad that you have as much fun as I do with the amphibians. I also hate to argue and have only made friends along the way with this great hobby. If the water rudders suite you then that is great. I have hopes that they will get even better! Just for fun, I include a video from the old days just to show the difference when the water rudders are deployed. Take care. https://youtu.be/IKm3dr7v5Pw
