The 1947 Hughes H-4 Hercules

They were altered as a part of SU12. During the beta I reported that they seemed to have been alter to to be too high. I noted similar temperature behavior as you with the cowl flaps and oil.

I reported this, but the bug was closed, indicating no fix at this time.

There’s a rabbit hole to dive down. In my own testing I’ve noticed #1 runs at a higher RPM too, even at the same MP. As for the cowl flaps the climb checklist notes “Cowl Flaps - CLOSE as cylinder temperatures permit” The During Flight checklist notes the following:
5. Adjust Cowl Flaps as necessary to maintain proper cylinder head temperatures

  1. Engine Operating Limits -
    Oil Pressures above 2000 rpm - 80 psi
    Oil Pressures above 1600 rpm - 65 psi
    Oil Temp 85 C
    Cyl Head Temp 218C
    Fuel Pressure 25±1psi
    Carb Air Temp 38C to 10000 feet
    Carb Air Temp 15C above 10000 feet

The plane looks and feels still truly awesome. I was just wondering, would it be possible to do a prestine state cockpitenviroment? I have no clue how much work this would be, but thought I just toss the idea out here. As of now, the paint at some points is chiooed away and there is wear and tare sprinkeled here and there (Cockpitglasses and so on) I just thought, would it not be cool to have a version of the cockpit the way it probably looked back in the 40 on the test flight, when all was still fresh, untouched and clean?

Most of the video shots are from October 2022, I reused them to make a tribute video . ^^

Did somebody already spot that the copilots yoke doesn´t hide 100%? Some elements floated in mid air when I hid the yoke:

Of course it looks funny, but I found it quite practical to have a sens of the yoke movement while it is hidden. So from my point of view it would be great if in general (for all planes) the stick/yoke could not only be hidden completely, but made transparent (something like 80-90%). So you could still see the yoke a little but also the instruments behind it… :slightly_smiling_face:

I will add this to the list of bugs to solve

Please don’t interpret this as me “bird dogging” you about this, but this didn’t end up being rectified before final release:

I just wanted to give you a heads-up.



I was thinking about taking this wonderful bird out for a proper flight some time soon,
If you guys have some good flight plan suggestions I would be more than happy to hear them. :slight_smile:
I’m trying to figure out as much as possible in the meantime, cheers!

Do what it was designed for and fly massive cargo from the US across the Pacific

Not a bad idea, any specific origins and destinations I should use?

I’ve often thought San Diego to Honolulu. The naval base there can take supplies and raw recruits to the main Pacific base. If you wanted to beyond that pick a date and fly Hawaii to wherever the Marines just took. I also enjoy Long Beach to San Fransisco for a shorter hop.


This is excellent, thank you.

I would like to second that thought. We expect more historical accuracy. It really threw me off the first time I read that because in 1927 things were not so advanced.
