Hi All,
SC, doing a tutorial that covers everything would be hard.
I was thinking mostly about the FSDS1 Aircraft. How to re-anamate rudder, elevators, add props to the AI. etc.
If anyone was interested we could do the fixes together and I could answer questions as we went along. That is if I know the answer.

Just fix one or two things at a time. It would take a week or so.
SeagullV,
The short answer is... You can just about do anything as long as you sanity holds up.
I4_Ro37 fuselage thing you be better off doing a new aircraft.
The Se-100 the front wheel would be interesting to try to make happen. Don't know for sure.
Adding points to wheels could be done, but then you would have to re-map textures and that is rough, and I don't know how to do that in FSDS1 models.
Removing parts is fairly easy. Adding parts is not too hard "if you have a part that you can hijack".
The lower turret on the B24 I built using modified parts and polys that I created, but it took forever.
I did try to lighten the antenna wire on the Helen but without success. I guess you just can't get much smaller than a line.
Demirroring parts on newer models is not too hard. I have not done it on FSDS1 models yet.
Adding LOD's is not the hard part. The question is where do you get them from?
I just did my first breaking parts. The time consuming part is you have to id and regroup all the parts.
I hope I answered some of your questions.
