300 Gallon drop tanks needed for OH P-38

Done...
If I am not mistaken, David Copely's P-38 G_H_J_L all used "lightning drop tanks" that were 300 gallons.
Let me go fire up AirEd and take a look at the drop tank capacities in the file.

I'm back.
There is a P-47 308 gal drop tank.
I placed both under DC's P-38J_20-FG_55-FS_Jeanne and they will mount and look fine, but you have to play a bit with the location numbers.

The DC P-38s did not have any drop tanks listed in the air file.
Which means that you will run out of fuel unless you go in and add up all of the internal and external gallons and change the air file for the 3 internals to equal total fuel divided by all tanks.
i.e., you have to add the 600 gallons of the externals into the total fuel contained in the two wing tanks and one center tank.
If I remember, they are 150, 150 and 120, so you will have to make them 450, 450, 120 to give you the fuel you need, as the air file will not recognize the fuel in the external drop tanks.

Ah, I'm using the OH P-38. I updated airfiles to bring things to G and H specs, in addition to adding paint schemes, fixing the ammo bug in dp so they have 2000 .50 cal rounds and 150 20 mm rounds. Also have a P-38J , forgot who did it but its clearly based on the OH.I created a P-38L out of it by mods, adding textures etc.I plan to release them once secure permission.They perform great.When fly the F, then G/H and then J/L can definitely tell the difference from the F model. I have later models upgraded to carry fuel, have yet to test a real long range flight.I was reading about the Yamamoto mission and if fly the mission was in RL, will def need the big drop tanks for low level , long distance
flying.
How do you add a fuel tank in the airfile? im not sure how to add a new entry for anything actually.
I did switch out the fuel selector for each panel, so can select main tank or the left or right internal tanks.The stock p38 fuel selector could select both, right, left, reserve, or drop.Now engines cut out when I select reserve.Airfile only had tanks listed as R, L, Center(main). Drop tanks work fine, will test the 47 tanks tomorrow.
I did the J model that is based on the stock CFS2 F model.
The only changes from F to G where more powerful engine and radio.
The stock P-38 fuel tank set up will work just fine for the later model. With the stock Fuel Selctor reserve is 531 * Fuel Center 1 Tank in AirEd. Drop on the stock Fuel Selctor will use both fuel tanks.

Sure did, I looked at the readme again.Very nice model.I tweaked airfile a little, added ability to feather props thanks to blood hawk I have the 308 gallon drop tanks attached to the G, not sure if need a mount but looks decent without one.Now question is will it make the flight for the yamamoto mission , a lot of fuel but will have to play with speed , rpm, mixture to see best results.Flying a low level like the actual mission will burn fuel quickly, sure it's been done in the 15 years or so of CFS 2.
My stock P-38F listed wing tanks as 90 gallons, center tank in airfile as 0 gallons. I had to change it based upon real life P-38F specs by adding the 120 gallons to the single listed reserve tank.
Then changed DC's P-38J to model real life specs:
P-38J had a range of 2260 miles, enabled by its 1010 gallon fuel capacity:
- 110 gallons, in two 55 gal. leading edge tanks
- 180 gallons, in two 90 gal. main fuel tanks, located in the wings between the engine nacelles and the center
- 120 gallons, in two 60 gal. reserve tanks, also between the engine nacelles
- 500 gallons, in two 250 gal. drop tanks
Since the airfile doesn't list separate leading edge tanks, I just modified the fuel capacity in all the tanks in the airfile to equal the 1010 gallons.
I don't know how to modify the airfile to allow for drop tanks or would have done that to DC's P-38s.
Yours will have the 2600 mile range with the 300 gallon drop tanks I suspect.

You must be using an airfile that is not stock. I just checked the stock P-38 and it has 120 gal in the tank.
With AirEd to add something you will need to open 2 AirEd. One will be the one you want to edit and the other will have the thing you want to add. In this case open the DC P-38 and the stock P-38. Copy the drop tanks from the stock P-38 and in the DC P-38 you want to paste it. Do this all by right click.
Also thanks to the warp fuel bug, You will never get the range that you would get if you flu the mission in real time.

Nice, I just updated the J model to those specs as well. What about the G? I will add a 300 gallon and 150 gallon DT to the DP file.Internal, 120 in main tank, 9 in win tanks? Same as the F yes? Just wondering if in the sim it will be enough to get me from Fighter 2 on Guadalcanal, fly the historical route at wave top level, make it to bougainville, combat, and back.Of course flight back does not have to be a wave top level.38 burns fuel fast unless cruising at high altitudes and like any plane when running full bore in combat.
ah, i rarely warp when i fly a mission unless just testing for specific parts have had to fix.Mission goes by pretty fast at time set to x4 and goes by quickly, set ap to hold alt and heading between wp if need to step away etc Guessing from my past testing with P-38 mixture, rpm, and throttle settings I can prob make it at 185-195 knots on low power and lean mixture flying the deck, prob have enough to get there on drop tanks, fly some combat and make it home, can always land and refuel in russell islands if needed.
