Noob Question - CEM and Prop

[louisv]

Think you are drving a bicycle, propeller pitch is like your speeds on a bike...

If you are climbing, go to easy speed...fine pitch

If you are going straight and level, you will gain speed by going to harder speeds...coarse pitch.

There are 3 types of props (and the 2 pitch on the hurricane), fixed, variable and CSP (constant speed prop). The CSP automatically keeps the same RPM all the time, so its like an automatic transmission, no need to change it as often (ex: spit IIa)...generally not during a digfight. With the variable (non-CSP), there is more work to do (ex: Bf-109)
