We are re-arranging the control by putting the spring which closes the throttle direct on the throttle to avoid the position of the throttle being dependent upon the slack in 2 or 3 joints. It is absolutely imperative that the controls should be fitted up in the way instructed as to angles of levers etc. so that the butter-fly valve opens slowly at first, and more rapidly afterwards. Mr. Elliott sends with this a revised instruction which should clear the matter up. It was very wrong on No.3 Goshawk (limousine) which caused some just complaints of difficulty of delicate control.
