Hello Stefan
That is correct those two animations are missing and if you would like to
do them again that would be great.
Here are the objects that now make up the nose gear.
...
So rotating everything from " collar" down should do the steering.
And compressing everthing from "nlowerstrut" down should do the
compression.
Did the wheels rotate as in aircraft rolling along the ground then no.
Did they rotate as in nosewheel steering then yes I think so.
Attached is a patch for adding nosewheel steering, nosewheel compression
and engine fan spin animations.
It works, but I'm not sure if it's correct. For steering I only needed
to rotate the "nouterstrut" object. In fact doing anything with the
other objects does just nothing. I noticed that, when trying to make the
tires spinning, too. Seems like everything is linked with this object,
but I couldn't find something in the .ac file.
