Here is a link to the MaxfordUSA site where they have a seaplane called the Neptune. From other posts I've read, it is nearly identical to the Seamaster 40. I had a Seamaster a few years back and loved it. I may get a Neptune to run a brushless conversion on it . . . let's see if it shows up under the Christmas tree this year.
