This is my RV-4 equipped with a Saito 150 engine.
I decided to change the color of the plane and doing it wasn't that hard. I think that the result is much better than the original scheme.
The Saito 150 has tons of power and the airplane is not affected by the extra weight (this engines weighs exactly the same as an OS 120 Surpass). Vertical climbs are incredible.
This plane is a blast to fly.......
