THE FT SEA OTTER is taking the sea by storm... and the AIR by surprise!!   

This plane is "Otter-ly" amazing!  Whether you are flying off water, snow or land this the SEA OTTER does it all!  The newest model from Peter "Mad Scientist" Sripol brings the sea plane design to a whole new light.  Peter designed this plane to allow for newer pilots to be able to have a simpler design for a better overall sea plane intro experience.  This might not be a "FIRST PLANE" for most people, but it is definitely a great intermediate option!  This plane flies wonderfully and feels great in the air and looks great on the water.  We hope you have as much fun flying it as we did!  So, grab one and let us know in the review section below about your experience... LET'S FLY!

Fun plane for Alaska

I live on a small lake so this is a great plane for me, summer and winter as it works great of of snow or water. This plane does like power, I suspect it is high drag and low weight, but if you try to fly at low throttle it doesn't go well (or I don't do well -- also a possibility). The airframe is resilient. It was my first non-delta ray plane and I abused it quite a bit. Eventually I filled the forward fuse with door/window crack filling foam to help compensate for damage and make sure it stayed afloat if I disabled it in the middle of the lake and had to deploy my boat. This actually seemed to help with the flight characteristics. My next build has flaperons.

Love ft and the way they do business

Love the plane, but I don't seem to have enough power with the b pack. It will not take off from water. It will barely stay in the air with a hand launch, also using 3s 2250 mah. Any thoughts or should I go to c motor. Maybe I put to much glue in it?
