Complex engine management

[Azimech]

It's true, early spits had only two prop positions, like manual shifting in a car. So it's very important to memorize the sound of the ideal rpm range, and act immediately on every expected deviation. So if you're going to dive in that spit, set the prop in coarse and lower throttle. This reduces your acceleration but will keep your engine healthy.

Also note that not only high temperatures are a problem, too low has adverse effects as well. And now we need to check both oil and coolant temperatures.

And don't forget the manifold pressure! If manifold pressure is too high and engine speed too low, detonation/pinging/engine knock will occur, temperature will start to rise sharply and you run the risk of burning holes in your pistons, destroying the big-end bearings or worse.

I've written a huge amount of info on these subjects, I'll look it up and post it here.
