If you nevered flown an airplane your better off getting a trainer plane to start off to learn the ropes of flying before going near the water. Once you understand the how to fly you can always add floats to land on water. Also a .50+ engine is a little big to start if you ask me, I would start with a .40 first. Just a suggestion!

What lake you plan on flying this thing on? Simcoe?
