White plane is my Rattler. I built this to test and prove my RO-Jett 40RE Bar Stock engine. It has one of my own pipes and Bolly prop. It  fly's well but is over weight. I out-smarted myself when designing the plane. It has the design numbers for a heavier 61 engine. When I put in the 8.2 ounce 40 in it was way tail heavy. Needed 4 ounces in the nose. Plane was light before all the extra weight. Has a Phil Granderson Diva airfoil and size wing with the rest being my mistakes. 58ounces! 630 sq. Testing over with someone want to buy it?
