ElAurens - it only takes few minutes to warm up Mercurys in a Blenheim, too - minimal cylinder head temp. is 200C, you got to watch it very carefully and make sure you take off on the lower treshold as they go very hot on full power. Ideally, roll into take off position when they reach some 120C and if you happen to go past 200, idle till the temp drops to 200 and only then take off. Don't forget to trim your rudder fully left and do a small run up to synch your RPM.
Warming up is much faster with rads fully shut (unrealistic on the ground I know), add more power in steps (you can hear and feel when the engine stops running rough). But don't forget to fully open them on your take-off run. Once airborne, coarsen your prop, lower your boost to some +4PSI (I think) and work with your rad shutters constatnly to keep her between 200-250C. She climbs slowly, the trick is to find a sweet spot between Coarse and Fine pitch in the area around 5 -30 percent.
