Hi Jim,

That's pretty much what I did. When I tried to steer with rudder alone, the model tried to dip its wing tips in the water. Eventually I was holding full down elevator and using aileron to keep the model level while using rudder to steer. But the model pointed into the wind the whole time. The best I could do was to get the model to move back and forth.

Thanks for the information. I don't know a lot about seaplanes as you can see. I figured a water rudder would at least allow me to turn the plane around.
