With reference to BY6/G22.3.29., this same point was raised with Hs.{Lord Ernest Hives - Chair} at the time of the experiment. It is understood that the heating of the servo is so slight that no difficulty will be experienced even on long hills. We feel however that the fabric should first be tested under these conditions before we actually go into production. DA.{Bernard Day - Chassis Design} | ||
