I posted this issue before in the 4.10.1 bug report, not much changed, so here I go again for 4.11.
The fuel quantity of the P-51D-20NA is somewhat off.
Inspired by the thread about the wrong fuel for the Betty I did some testing again and notived not much change to the last time I checked it.
In short:
Test was a simple runtime check on the runway with 51" 2600rpm (70% for both).
100% fuel should be a ful auxiliary tank (85gal) and 2 full wing tanks (92gal each), giving 269gal total.
With this much fuel the engine ran at the given settings for ~152 minutes, burning ~1.77gal/min.
The auxiliary tank, from the time the needle started to move emptied in ~55 minutes, saying its 1.55gal/min.
Adding 2 drop tanks and lifting the fuel to 419gal total, engine ran for ~212 minutes, burning 1.98gal/min.
There are some possible error sources. I did the test with all available fuel quantities (100% - 10%) and there are more oddities !
No range tests done yet due to lack of time at the moment.
If you, TD, are interested in all the test results for all fuel quantities, let me know and by the end of the month I will do range tests as good as I can and write a comprehensive summary of all the results.
Wish you all a relaxed sunday !
