| contd:- -3- HS {Lord Ernest Hives - Chair} 1/LGS.1.5.21. -------------- with free steering, we get bad steering wobbles. We have now arranged the friction on one pivot - we tried it on both pivots, but it was too much. The exhaust system on GoshawkAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine 1, is very efficient although it is good as regards silence, there is very little power absorbed. The maximum increase at any speed up to 3000 R.P.M. with free exhaust is, 1.5 HP. HS. {Lord Ernest Hives - Chair} [Watermark: DICKINSON] [Watermark: MADE IN] B. R. {Sir Henry Royce} H. {Arthur M.
