A few things I've noticed. The manual doesn't necessarily correspond to what is actually being simulated. There are also a few bugs:
1) When looking over the left shoulder to check that the gear is indeed up, the gear fairing door is not modeled from the VC, however the right side is.
2) There is no flap indicator on the left wing, so there's really no way to visually check how much flaps you have applied.
3) Oil cooler flap switch logic makes no sense. From what I can tell, it, and many other switches are actually spring loaded toggle switches. In the sim they move through four positions, each only seeming to open or close them, and then a middle switch that does something, but does not correspond to the manual. I have no clue what's going on with this, or any of the intercooler/oil cooler/coolant flap override switches, making it impossible to operate the engines properly. Some switches, such as the oil cooler flap switches are actually supposed to operate in automatic (up)/manual (down)/manual open (down left)/manual close (down right), with the latter two being spring loaded back to the manual (down) position.
4) Mixture is set to auto (=1) in the aircraft.cfg, however, the manuals state to set it in positions that correspond to the real world.
5) No oxygen mask visible on pilot.
6) Prop condition switches do not appear to work like the real thing, and according to the manual.
7) How do I tune frequencies? I see that the knobs on the control box correspond to a frequency, but how do I select them?
8) Oil cooler doors are not symmetrical on both left and right engines, regardless if they are put in the same position (as far as I can tell).
Alright, so it might sound like I'm bashing the product, but that's not the issue. What I'm confused about is what actually happens in the sim, and the supplied documentation. The site says
In the Milviz P-38L, your actions (or lack of them) will have consequences: Not only are we including full systems modelling, but it's now possible for those systems to fail. You'll be required to manage your engines properly and to pay close attention to the instrumentation. Start-ups and shut-downs can be performed according to checklist, and failures will need to be acted upon as prescribed in the included pilot operating manual!
When I try to follow proper instructions, I just get strange feedback from the plane, gauges and switches. May I suggest creating a new manual that corresponds to the aircraft you simulated, or perhaps do some recoding? The problem is, I have no idea what you are asking for simmers to do, and so I have no idea how to correspond to what it's telling me.
I hope that makes sense? Simply put, I can't use the manual that's provided, and there are many features not documented anywhere.
Okay, that being said, it's a beautifully modeled aircraft. I've sat in a few P-38s and this is the first simulation that seems to get the feel of the interior correct. Sorry if it sounds like I'm bashing the product, but I'm very passionate about the P-38.
