1) It may be different between phones, but on mine I can pick Internal Storage from the menu on the left in File Explorer.

2) Should do

3) An example from one of my planes:

Part id="2" partType="Fuselage-Body-1" position="0,2.743354,0.7562499"

rotation="0,0,0"
drag="0.1292781,0.1292781,2.755342,2.755342,5.156407,5.156409"
materials="0"
FuelTank.State fuel="0" capacity="0"
Fuselage.State frontScale="2,4" rearScale="2,3.34" offset="0,-0.33,6.5" deadWeight="0" buoyancy="0" fuelPercentage="0"
cornerTypes="2,1,1,2,2,2,2,2"

That's for a fuselage block. So, to break that down bit by bit:

• Part id="2" - every part has a number to identify it.

• partType="Fuselage-Body-1" - this identifies the type of part.

• position="0,2.743354,0.7562499" rotation="0,0,0" - these define where the part is and how it is rotated.

• drag="0.1292781,0.1292781,2.755342,2.755342,5.156407,5.156409" - I don't think drag can be changed, because it is reset when you load up the level.

• materials="0" - the colour.

• FuelTank.State fuel="0" capacity="0" - how much fuel the part holds. I'm not sure what the difference between these two is, I've never really played with it.

• Fuselage.State frontScale="2,4" rearScale="2,3.34" offset="0,-0.33,6.5" - the front width and height, back width and height, then the offset, which defines the length, run, and rise.

• deadWeight="0" buoyancy="0" buoyancy="0" fuelPercentage="0" - pretty obvious

• cornerTypes="2,1,1,2,2,2,2,2" - 0 is hard, 1 is smooth, 2 is curved.

@Skua I am very confused...
1) what category is internal storage in?
2) will any text editor work?
3) Is the text in, like, code style?

And on mine its stored in sd local hope it helps

This is exactly what i do and i use the same phone :)

The files for your planes are most likely in Internal storage\Android\data\com.Jundroo.SimplePlanes\files\AircraftDesigns. They may be elsewhere if you store your files on an SD card. Anyway, find those, then open the one you want to edit in a text editor. Once you're done, save it, then reload the plane in SimplePlanes and your changes will take effect. I recommend backing up any planes you edit, it's easy to break them
