I bought a KF5 that had been completed but phase I not flown off. In checking the empty wab it is near the aft limit. The plane flies fine and behaves in all stall configurations and phase I is complete. Still I am concerned about loading the plane up until I have a better understanding of the cg as everything I put in the plane will move the cg farther aft. Has anyone else had experience where the weight distribution for a model 5 is differs significantly from the example in the builders manual?
