I'll keep the transom angled because I rarely ever use water rudders on my float planes anyways and i think the angled transom really looks good on the plane.
This is the plane here. wish i had a digital camera so i could post a pic of it all fleshed out with balsa and ply, still have to build the wings, cowl and floats. Should be ready
by the time the ice leaves the lakes for its maiden flight.
