Maybe some of you remember when I signaled I found out that RPM indicators weren't showing correctly values. In fact, it seemed strange to have values remaining around 3 to 4,000 rpm.There are 2 points to correct this:
- to modify in OPS the max setting of the RPM indicator (4,000 works fine)
- to modify the gauge, in order to display correct values STef ------------------

My RPM indicators show the right values.. TS IP: Logged |

Tailslide,Let's take the Spit Mk Ia you made as for an example. At full throttle, it shows around 3.500 rpm, about 1/3 of the rpm gauge.
I just think that the display should go upper. It gives feeling the throttle isn't at max power. Tell me if you got the same result. STef ------------------

If I set the engine to 3000 RPM the guage displays 3000 RPM. How is it not showing the correct values? TS ------------------

okay, I'm talking in an aesthetic way.My point is the rpm gauge should be redone to match the maximum rpm values.
If the engine can't beat 4.000 rpm, so the top of the gauge should be this max rate. There are no needs for a 9.000 rpm gauge if it can't be reached.
If I'm wrong, give me a link where I could check this (with Spit mk Ia). At full power, the needle should move all the way of the gauge. This my 2 cents and opinion though!  STef ------------------

right now the biggest problem with rpm guages IMO is that they are tied to throttle instead of engine rpm in openplane. Such that if you change the engines maximum rpm (to simulate damage) it takes no effect.IP: Logged |

Ok, I just tried all the americal planes that shipped with the game (B-17, P-38, P-51). Something is wacky with all of them. I noticed this when I first got the game, but didn't really bother to see what exactly was wrong with it. This is what I notice when making throttle adjustments (the same thing happens on all 3 planes). At idle, all engine instruments read normal idle readings, but as soon as the throttle is nudged up.... say to 1/8 to 1/4 throttle, all the instruments jump up to max throttle readings. Apon short throttle increales (say in jumps of 1/6 throttle), the needles would jump up to a higher value, but then fall back to the previous max rpm value. If you continued this patern, the gagues would do the same thing up to max RPM. Now if at any point between 1/8 and max throttle you decrease the throttle a little bit, the needled would dip down, but then return to max throttle readings (untill at idle).... I think it would be more realistic IF the RPM gague was slaved to the throttle. I mean, this is what you use to control the RPM anyways, and there should be no difference between the throttle position and the RPM values at any given point.... Besides, RPM settings are sometimes measured off of how far foward the throttle lever is anyways.------------------

The planes in SDOE are simulated as constant speed variable pitch, the RPM is set in the .sm file. TS IP: Logged |

This isn't nearly as distracting as the fact the speedometer is true air speed not indicated air speed. TS

"constant speed variable pitch" aaahhh ok.... but still, thats very extreme! the RPM should only vary by a few humdred. It's definately not enough to make the prop move at max RPM at minimal throttle.------------------

FWIW, war emergency power and takeoff power on the p38 was 3000 RPM. Cruise was around 2400 RPM. But since we can't overheat the engine in SDOE and we have no engine controls.. Anyone have a pic of a p38 tach? TS IP: Logged |
