Responding to a different problem, LVG overcame the tail heaviness of its machines by increasing the sweep-back of the wings. Late production by SSW and LVG became obsolete, hence many aircraft were finished as trainers with lower performance engines (Argus As.III or NAG C.III).
LVG addressed the problem of its aircraft's weight at the tail by increasing the wing's curvature. Later models produced by SSW and LVG became outdated, so many planes were converted into trainers with lower-powered engines (Argus As.III or NAG C.III).
