The P38s wep still doesn't work properly on one engine, you can wep #1 if #2 is dead, but you can't wep #2 if #1 is dead.

From what I remember, the P38s wep was independent of each engine, however, the battery recharge was run from the #1 engine.

Also, from I remember, the P38 had outer wing reserve tanks on the P38L. From what I was able to put together by a vet was that these were used to take off and land primarily.

Now, if you want subjective, let me know.

Also...I have an extra throttle on my stick so I mapped it to the RPM. On the 38 it only affects one engine and not both.

Great Idea!!

This wep "bug" was always like this in AH1 as well. It's not a new thing but good to bring up. I think HTC just modeled it that way. I'd imagine 1 engine carrying a plane that is meant for 2, with wep... It would probably over heat very quickly.

The P-38L had a generator on each engine. Yes, WEP was independent on the engines. The fuel is independent as well, unless you cross the fuel over.

The P-38J introduced 55 gallon wing tanks in the leading edges of the outer wings, they replaced the leading edge intercoolers. They were not reserve tanks. There are reserve tanks, they are used for the first 15 minutes of flight to drain them because the fuel vapor return fills them back up. Veteran P-38 pilots told me that after emptying the reserves, they switched to the outer wing tanks to empty them next, unless carrying drop tanks. Emptying the outer wing tanks made it roll faster. With drop tanks the order would be reserve 1st, then drop tanks, then outer tanks, then main tanks, then back to reserves if needed.

By the way, I notice the fuel tank indicator reads that fuel is burned one side at a time. Is this how it is actually modeled? If so, this would create CG issues, as the plane would become very unbalanced.

On one engine, the P-38 could cruise at 255 MPH at 20K feet. I have no data for single engine WEP performance. I doubt there is an endurance difference for WEP between single and twin engine operation.

By the way, last night I took a hit in my right main fuel, but I had white smoke coming from my left engine as if it were overheating. It still smoked on landing. But the only indicated damage was right main fuel. The damage model of the P-38 appears to be either bizarre, or filled with bugs, or both. I do not think it has been updated in AH II.

Another thing I notice is that on takeoff, the elevator trim is run all the way up, and I have to manually set it down. The manual says 11 degrees up trim. Also, it yaws to one side on takeoff. The brakes do not hold well either. They should hold the plane still on the runway at 54" of manifold pressure.

By the way, what stick is it that has two throttles? I'd like to have two throttles. I'd prefer two throttles independent of my joystick, but I'd settle for two throttles onmy stick if I liked the stick well enough.

Many guys have been doing this for quite a while now.

There is a stick made by Suncom that has the dual throttles, however, its gameport.

I haven't seen any dual throttles set ups in USB yet, and the CH Throttle Quadrant isn't due out until the end of the month.

Thanks Virgil, for the assistance. Though I still think the generator was on #1 only, at least on the early P38s.

I have a CH throttle and the stick also has a throttle on it. RPM never meant a whole lot in AH1, so I didn't map it, but as its integral with the new fuel burn eeking, I did so. Would be nice if it covered both engines as the throttle does.

Speaking of, this new stick has a twisty rudder axis on it and as I already have pedals I was trying to think of something to map it to but can't seem to come up with anything constructive...anyone?

Can't remeber if the is a set up for a panning view left/right. That might work, if possible

Like I said, the L model had a generator on each engine. I think the first model with two generators was somewhere along J-10-Lo.
