RPM and MAP

[Batz]

I have read Cav's post previously about the f6f and someone mentioned the p51.

Looks like more testing needs to be done.

I just think for response it is easier to have RPM adjusted via throttle control.

You still aren't getting it.  In most RW flights you only adjust RPM a few times: takeoff; climb; cruise; landing.  In a WWII dogfight  they probably set it for climb and didn't mess with it much after that.  Mapping RPM to your throttle would be like mapping your landing gear to the same button as your flaps... not very practical.

Great information,

But all I really wanted to know is if I could map RPM to my throttle control with or instead of MAP.

I just think for response it is easier to have RPM adjusted via throttle control. I thought this was more realistic but it seems not to be.

Has anyone changed there RPM or throttle mapping?

Hum ... you may want re-read my post. Imagine you play a car game where you map your"gear shifting" on your accelerator pedal.

Hehe,

I like RA's rsponse about mapping my gear to my flaps. I am still considering doing that lol!!

I wonder what else I could come up with? Maybe I could map fart sound to my guns, or a flush sound when I drop a bomb?

Don't mind me I'm a little tired;)

This is first evidence I've seen that RPM was modeled independently from MAP in AH.   -Blogs

Having tested the F6F-5 in the past I can say prop pitch definitely affects fuel consumption.

F6F-5 fuel tests

Chart 3 and 4 will show comparison with diff MAP and RPM. Constants were alt, loadout and cruise speed.

Thanks for the time and effort to do these tests....  I appreciate it.  It's gotta take alot of patience to do these.  (And even more patience to put up with folks like me "whining" about your hard work.)

But......

I cannot determine what caused the variation in the fuel consumption, MAP or RPM, each test had different MAP settings.  Wouldn't MAP changes skew the fuel duration and range of the test, if you are trying to test RPM to fuel relationships?  MAP would have to stay constant to test the range and duration of RPM changes.  Speed would change as a result, but this would give a closer idea of range and duration, true?

Thanx!

Wow, you guys are out of it aren't ya.

I had RPM mapped to my sticks slider since early last year (earlier mebbe even?).

I now have it mapped to my TQS dial (one of them).

RPM gives less drag during an engine out (esp tiffie), better fuel efficiency (quite helpful in the La's), and also useful for generating less thrust (especially in the jets). You notice a big difference in slowing a 262/234 down using RPM and MAP for landing.
