| DA.{Bernard Day - Chassis Design} from HS.{Lord Ernest Hives - Chair} 49910 HS{Lord Ernest Hives - Chair}5/LG9.4.24. With reference to servo leverages. We have compared the leverages on the WW. agreed scheme servo with the original slow speed servo instructed by Rg.{Mr Rowledge} which gave us reasonable results. We attach herewith figures which show that we were using nearly twice the pressure on the servo. Hs.{Lord Ernest Hives - Chair} | ||
