Developer      

Remember all of the naysayers when this sim first came out, I was one! Where are the addon aircraft? I eat my words in your presence. 
I've downloaded all of these aircraft and each one of them worked in CFS3 the first time!
On CFS and CFS2 I ran into alot of problems getting the first new aircraft to work properly.
Thanks for posting the list with hyperlinks.

Thought I give a quick headsup.
A beta of HerbieG´s B-17 will be available probably by Monday 21 or Tuesay 22at Avhistory.

If you'll check over at the Sim Outhouse CFS 3 downloads sections there are also

betas:  
Me 334 (+ an extra skin)
B-29

Finished:
Fw 190D
Ta 152Cv7
Ta 152C-1
3 or 4 P-40s
plus several others not listed above.

Also if you're interested in the Great War birds,
Taz has a beta Fokker E-IV Eindekker at http://www.tazsdesignshop.com/
and there's a Sopwith Pup that's also at S-O.

Kinda shocked not to see Tom Stovall's standalones on the list. Thanks Tom for the great work. I do injoy http://www.shasta.com/stovall/CFS3Downloads.htm

I know the P51's (the HO and Old Crow scream) out do the stock big time and the P40's, is all its on, but im not sure about the rest of the others. All i do is download them, install them and fly them. You might want to download and have a look at the files if you know what your looking for in a change other than stock.

Also there are a few planes here as well http://www.simnetwork.com/listing.php?cat=14 ; But you need a good popup killer.

Big thanks for getting them all down in one place. I can see one or two I must have overlooked. Cheers.
