This Aircraft of the month is the Volmer Sportsman, This is a design I just recently learned about from long time friend and fellow EAA member William Wynne from www.flycorvair.com Reading the spec’s a Corvair power-plant would actually work on this bird. It can be setup as a Pusher or Tractor configuration, while the pusher configuration gets the prop further away from the cockpit and water spray.

This aircraft first flew in the late 1950’s and actually has quite a bit of history to it.
This aircraft is very similar to a Home build sea plane I am familiar with the Anderson Kingfisher: https://gouldaero.com/2020/03/15/anderson-kingfisher/
