So basically i should be opening radiator (and oil rad?) on start up - then closing to half way on take off. then throttling back as soon as airborne?

well, for the start the pitch should be on fine to get the best acceleration. So you have also to be carefull not to overrev the engine. And overrev with a cold angine is even worser !

As example, when you have the Mercury of the Blenheim at the desired 200°, the propeller at fine (you have only the two setting fine and coarse in the Blenheim) giving FULL throttle is very dangerous as the revs are very high..........i personally dont get over 2400rpm , 2500rpm only for short time. But, thats part of the game, everyone has to make his own Pilothandbook ................
