I built mine with the last bay removed and rounded tips. Also moved the elevator servo to the rear, and used pull/pull for the rudder. As a profile mine looks like a Corsair, so a rounded cowl would be perfect for it, maybe round the tail feathers too for a more Corsair like look. I found mine to be too nose heavy and set it up with flaperons, to help slow it down, so my gear is a bit squashed from too many hard landings, so need a different gear now. I got the balance right now, so my landings are much more gentle.
