The instability issues on almost all planes have more to do with set up than design. BJ Craft has a good product as you can see by how many are being used in competition today. The Allure uses my setup methods and takes the guess work out for the modeler. Although if set up incorrectly , even this plane can give you problems. My goal was to provide a good basic launching pad for success for all classes, experience level , and power systems. This gives more options to the modeler. BJ has done the same with his models, not an easy task.
There are no bad designs out any more really Just busy modelers, we all look for short cuts but in competition, there are none. Just pic the plane you like and go have fun.
