Kappi Posted April 18, 2021 Share Posted April 18, 2021 Hello, I noticed that there is no RPM drop in the Spitty when switching one magneto off, like you do during the run-up check. According to the RL manual there should be a drop which shouldn't exceed 150 rpm. Also the rpm drop can be heard in this YT video: Please find attached my trk.-file. Greetings and thanks for checking out, Kappi Spitfire Mk.IX No RPM Drop on magneto switch 1 ___________________________________________ [sIGPIC][/sIGPIC] Looking forward to it, Belsimtek!:thumbup: Link to comment Share on other sites More sharing options...

grafspee Posted April 21, 2021 Share Posted April 21, 2021 I just tested it. Definitely rpm drop is present in spitfire.

You have a noticeable (tachometer and sound) RPM drop when switching one magento off and keeping the other one on? ___________________________________________ [sIGPIC][/sIGPIC] Looking forward to it, Belsimtek!:thumbup: Link to comment Share on other sites More sharing options...

No, rpm drop will depend on sparkplugs conditions, if rpm drop is higher then 150 then you need to replace or check left or right bank. So in RL situation you wont change spark plugs before every flight, so this test shows pilot how good or how bad sparkplugs are. In case of DCS you have brand new engine every time you pick plane, expect minimal rpm drop.

The only warbird in DCS which has a serious and audible RPM drop during mag check is 109. Fws are less noticeable, while in all Allied birds the drop is minimal and thus not audible at all. But it's there allright. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10. Link to comment Share on other sites More sharing options...

Well, I'm aware of that, but nevertheless would it add more immersion if all the engines had a 'used' sound/behaviour and won't behave like brand new engines. For example, like Art-J mentioned, the 109 has exactly that drop. Let's see what the devs make out of it. ___________________________________________ [sIGPIC][/sIGPIC] Looking forward to it, Belsimtek!:thumbup: Link to comment Share on other sites More sharing options...

For example, like Art-J mentioned, the 109 has exactly that drop. Let's see what the devs make out of it. 109 has different engine, and it has brand new engine as well.

In the DB605 of the 109 you should burn free the plugs or change them having a drop of more than 50 RPM, which is definitely more right now in DCS. So I don't share your opinion that the engine in the 109 should be brand new. But I agree that we disagree. ___________________________________________ [sIGPIC][/sIGPIC] Looking forward to it, Belsimtek!:thumbup: Link to comment Share on other sites More sharing options...
grafspee Posted April 25, 2021 Share Posted April 25, 2021 (edited) At least ED always says that engine and plane are brand new. Anyway original post was about no RPM drop while checking Mags, which is obvious not true.
