We send herewith N.Sch.4950 showing a strengthened servo main lever. Tests made on the present lever G.83903 have indicated that it is quite strong enough for the present duty. However, by calculation, this lever is the weakest part of the system and we think that an increase of the strength of the lever should be made at the first convenient opportunity E/HDY.{William Hardy} N.Sch.4950 herewith. | ||
