Spectre(Codename for Phantom III) - Brake Leverages. ------------------------- Herewith is N. Sch.4054, diagram of the brake leverages, foot and hand. The direct ratio of foot to cam has been reduced to the neighbourhood of 12.5 to 1 to meet the objection raised on the Vulture(Experimental 6 CYL OHV LONG STROKE / Aero Engine), and we are reckoning on a servo output of about 3.
