I want to add, that the sim models the MBG/Jumo 213 right. Only the manual in this regard is wrong.

"The pilot simply has to move the throttle lever to set the desired manifold pressure. The "Bediengerät" takes care of the rest, setting all other parameters to allow the engine to properly operate at the desired manifold pressure, given the current flight conditions." As i mentioned it in another thread, it's nonsense for the Jumo 213. The Jumo was operated only by rpm and observing the fuel consumption. The gauge for Manifold pressure was only for monitoring purposes.

I don't get it, what's so hard to take off in the dora? Flightstick backwards to lock tailwheel, throttle to full power, at 150 - 170 km/h flightstick to center position and the Dora get's airborne. No need of brakes. If the Dora goes left, use the rudder a little bit. That's it.

Ordered it. Well done LN! :thumbup:

5. Verify take-off position by observing the mechanical indicator on the wing. That's right. There's a little hole in the right wing, showing at which degree the flaps are positioned. (30° or 60°) Normally, there is one on every wing, it's reported and should be solved with the first patch, i hope. Edit: Sithspawn was faster.

With MW50 switch off: (max power output: 1750PS) 3000rpm = Kampf- und Steigleistung. (combat and climbing power) 3250rpm = Start- und Notleistung. (start and emergency power) You can use "Steigleistung" as long as you want. Notleistung was limited to 30 min, if i remember correctly. With MW50 switch on: (max power output: 2100PS) 3250rpm + MW50 = Sondernotleistung. Something like "special emergency power". That was limited to 10 minutes, afterwards you had to cool down the engine by lower rpm for at least 5 minutes. Over 5500 meters, you have to turn off MW50, because the critical height of the Jumo is reached. That means, MW50 has little to no effect. Historically, not all Dora's had the MW50 boost system. The auxiliary tank could be filled with extra B4 too. So it was not always available. Hope it helps.

Wieso vereinfachtes Flugmodell, ist doch das gleiche wie bei der richtigen Mustang. Nur fehlen der hintere Tank und die Bewaffnung. Korrigier mich wenn ich falsch liege, aber so hatte ich es verstanden.

Du hast es einfach drauf... ;) Vielleicht hast du den Autopilot der Huey an? Dachte da gab's sowas. Ansonsten poste doch einfach mal ein Video.

If you start the Dora in flight, the oxygen valve is closed and the artificial compass is in the "Fest" position. Nonetheless both instruments are working anyway.

The fuel descriptions on the dora are wrong. The Jumo 213 A-1 was flown only with B4 (87 Oktan) fuel. If you look at the skin of the dora, you can see there are only C3 (100 Oktan) signs. Instead of the C3 sign on the left side behind the canopy, there should be a MW50 sign. All other should be B4.

Hi Blech, about GM1: http://en.wikipedia.org/wiki/GM-1

The Ta152H-0 had no MW50 / GM1. Only the H-1 had both of it.

Maybe there's a reason why it was done this way, oh my gosh, sry doesn't happen again... :( Over and out...

I don't have any problem with that. It wasn't my concern. I said it's authentic, dunno what's your problem?

I know it's strange, but all pictures of the ZSK244 show "wagerecht". If you look into the manual of the ZSK, it's called waagerecht... :D Do we have an ZSK244 expert?^^

It's authentic, nonetheless it's a typo... What i can imagine is, the word waagerecht is to long on the right site, so they wrote it with only with one "a"???

From original manual of the Dora 9: 3250rpm = Start- und Notleistung (with MW50 Sondernotleistung) 3000rpm = Steig- und Kampfleistung 2700rmp = Dauerleistung I don't know the rpm for saving fuel, but 2200 - 2400 should be ok. Can you confirm this Yo-Yo?

Nice post, that's something i want to know, too (throttle start position). It's possible in the A-10C, so it must be possible for the Dora too.

Very nice read!!! Thank you Yo-Yo for your hard work! It's nice that a real Dora pilot helps to get the best modeled Dora of all time... :thumbup: Release it now!!! :P

Hi RNeves, no, there's nothing in the manual. I miss it too. From what i know: The version we have, a Dora with MW50, it should be 10 minutes. After that, a pause for at least 5 minutes with normal power setting. After these 5 minutes, again 10 minutes with maximum power setting.

That's correct. But the more important thing was, the increase of speed was only around 10km/h...

Where did you get your information from? :doh: Only A-8/A-9 had an auxilary tank. FW190 Antons never used MW50!!! The first increase of power output was extra injection of C3 fuel together with a higher boost. This was allowed only up to 1000 meters and only for jabos. That was in summer 1943. By july 1944, it was adopted for fighters, but without the extra fuel injection, only higher boost. It could be used for the Bodenlader and the Höhenlader. Increase in speed was approx. 20-30kmh. Machines with "Erhöhte Notleistung" had a yellow circle on the MG131 cover. MW50 and BMW801, forget that! It was tested, but was never used in a combat unit.

Isegrim is right. On Daimler Benz and BMW engines, the pilot controls the manifold pressure direct by the power lever. You know 1,35ata is Kampfleistung, you move the lever forward and watch the manifold pressure indicator. The pilot didn't control the rpm directly. Every maifold pressure value had it's own rpm value. Daimler Benz 601 or 605 -1,42ata with 2700rpm = Startleistung/Notleistung -1,35ata with 2400rpm = Steigleistung/Kampfleistung On Jumo 213 engines, it's another story. The pilot doesn't care about manifold pressure. He choose only the rpm setting and has to watch the fuel consumption. The manifold pressure was only for monitoring purposes. That's what i meant. I hope it helps.

+1 :P

I have something to add. Page 24: "The pilot simply has to move the throttle lever to set the desired manifold pressure. The "Bediengerät" takes care of the rest, setting all other parameters to allow the engine to properly operate at the desired manifold pressure, given the current flight conditions." That's not right. The Jumo 213 engines were flown by rpm. The manifold pressure was irrelevant, only for monitoring reasons. In the manual of the Jumo 213, doesn't matter which version, it says, the engine is flown by rpm! That's the reason why all power outputs are given with "rpm" and not with "ata". 3250rpm = Start- und Notleistung 3000rpm = Steig- und Kampfleistung 2700rpm = Dauerleistung and so on...
