Herewith is N.Sch.4306, Diagram of the Brake Leverages in the Semi-servo system now being erected on SpectreCodename for Phantom III. The only modification, which we should like incorporating in the system when possible, is the substitution of the intermediate lever shewn on N.Sch. 4379 for the one now on, thereby increasing the front braking.
