RE: Newbie to seaplanes
The salt water is bad for electronics and engine.
If I were you and were going to fly in salt water I'd get this setup:
-Plane:Falcon Trading Ready
-Engine, I'd invest as little money as possible in the engine since it might be spent pretty fast in salt water...Second hand two stroke 46-51 size.
-Bag the reciver in a latex glove to waterproof it.
-Seal the wingseat with latex to prevent spray from coming into the radio compartment.
ps. I don't fly off water. this is just my "theoretical" thoughts to help you with some ideas.
