CEM in the Yak, best RPM / Prop-pitch question

[oho]

How do get the best performance in the yak with which prop-pitch setting. 

In the specification for the Yak-1 thread it is said:

 Engine RPM has an automatic governor and it is maintained at the required RPM corresponding to the governor control lever position. The governor automatically controls the propeller pitch to maintain the required RPM.

Are there any rules of thump which rpm are the best in which conditions?

There is no hint regarding the best RPM.

Hey oho,

check out this youtuber's videos:

 

 

 

This is great for info on the Yak and how to use it in combat.

Also check this from the guides part of the forum.

All that info is also shown in-game in the map screen in single/quick missions.

Official war guide for this engine stated simply go full prop and throttle. You theoricaly can gain some kph by reducing slightly rpm during level flight. You can gain approximately 20 kph by closing conopy and 6-7 by closing radiators (to maintain nominal temps). You can lose almost 10 kph if forgot to switch second gear from 2000 m up. Same leaning gradually mixtures above 4000m gives some more kph.

Yeah, the M-105PF is by far the engine that's least vulnerable to mishandling. It was basically designed to never go above its safe rating (which is why it is so weak compared to contemporary engines), so that it could be run practically without a care at full power and RPM all day long. In the long run doing this of course still would reduce time between overhauls and pilots were often reprimanded for flying entire missions at full power, but it was fairly safe to do so.

 

Apart from heat issues and fuel consumption, there really is no need to ever reduce throttle or rpm.
