Here's a general checklist for initiators of collaborative projects:
1) What will you contribute?
a - The model
b - The textures
c - The flight dynamics
d - The soundset
2) What will you do if you do not find people willing to participate?
a - Not start in the first place.
b - Do it entirely on your own.
c - Do something you are able to do (i.e. model or soundset) and upload it in the home of someone else picking it up and finishing it someday.
3) Are you willing to learn the tools of the trade to make the aircraft entirely on your own?
a - Yes
b - No
4) Would you be willing to pay others to do one or more element (i.e. FDE, sounds or else) of the aircraft to accelerate development despite going for a freeware release?
a - Yes
b - No
Best prospects for success:
- Picked one or more replies for question #1.
- Picked b or c for question #2.
- Picked a for question #3.
- Question 4 does not matter, but should be kept in mind.
Worst prospects for success:
- Picked none for question #1.
- Picked a for question #2.
- Picked b for question #3.
- Picked none for question #4.
The reality is that aircraft projects take a whole lot of time and unless you're at least willing to go for it on your own, chances for success are nonexistant. You might be able to pick up some other contributors on the way, but expecting to contribute nothing more than hollow ideas and information and having other people do the real work will get you nowhere.
Good luck anyway.
