| To HS.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} Copy to CJ. ORIGINAL. RE ARMOURED CAR TEST.X4195 I think it would be a good thing if you took one of our standard chassis where there is a short steep hill and make tests of a known gradient of 1 in 5, where it is quite safe in case the load is too much for the power or brakes, and load up the chassis a few cwts. at a time, and find out the limit of weight that the brake will pull up on this grade from a slow speed, and see with what load the low gear, the clutch and the engine are capable of starting on such a grade.
