I am currently building a XL with a Jett L90. From what I have read about the plane (Patriot XL) is like the GP f-15 I had. I CG it to spec and it took forever to take off and landed like a rock. I moved the CG back and the more the better the F-15 got. The f 15 CGed way back was awesome. It sounds to me a CG error ratherthan a design one. Got to get the nose up. My first question has anyone moved the CG back. It will not be long before my XL takes flight and sure would like to know.
