The He 100 was interesting in that the radiator could retract while in flight, leading to lower drag. I don't think this is worthy of a special key, but I would like to tie it to the gear so when you clean up it raises.

The 100 also had two small "posts" on the wings painted red, when the gear were down they would raise so you could see if the gear worked (instead of using a cockpit indicator).

What's the basic concept here? Are items like this tied to the movement of the gear, or are they simply all tied to the same input?

This will also work with the AI I believe. The AI knows the gear is actually gear to raise and lower by the DOF used. Copy/paste the DOF property list to the radiator and edit the direction and axis of the DOF. Then when you press the G key, the gear along with the radiator will raise/lower. The same for the little gear indicator poles on the wings. Dont forget to delete the oscEndDisabled and EndHidden in the DOF property list for the radiator and the gear indicator poles.

Do you know how it figures this out? Is it by a name somewhere?

Ahhh, I get it.

Got it, I think. Just to make sure, when G is pushed (or the AI does it) anything with a particular type of DOF will react - is that it?

Very cool. Actually the poles should disappear, they retract into the wing.

Do you know if the drag for the radiator will work OK? Is there something I can do to make the drag go to 1/2 when it's retacted? I assume the gear drag goes away automatically when it "disappears".

Any part with the Gear DOF property list will move when you hit G or the AI raises/lowers the gear.

For the radiator to have drag, it MUST have a drag airfoil. I have no clue about airfoils however....

Maury, ArgonV is correct. The keyboard.inp file contains a line "cmdGearToggle = G" so when you press the "G" key it invokes the "cmdGearToggle" command, Any dof with this as the command will be started. Even if it is by the AI.

As for the drag from the scoop. Look at the landing gear in the level with the wheels, you will see something like "g3310" this contains drag properties, so that when the gear is lowered it will produce drag. When the gear is up and in the "oscEndDisabled" position, the airfoil properties are disabled and does not produce drag.

You can copy the "g3310" object from the gear and paste it to the scoop (it will be renamed to something like "g33101", this will make it a child of the scoop. You will need to change the name of the object to be disabled like "oscEndDisabled 'scoop"

You can take a look at the P-51D beta 5. It has a scoop with a drag airfoil added. However it uses a different command and instead of the airfoil producing drag, it is designed to break off in order to call a function. The setup would be the same.
