Just checked and forgot to include Ben's airfile.
My apologies.
This evening I will load up the correct package.

I used Ben's value as a test for the other 777 versions.
After having done several landings with the 777-200 GE and the 777-300 PW  with their original airfiles I came to the conclusion that they too had little spoilers drag.

Then I tried Ben's value and it was way better.
Therefore I used that value for all liveries.
CS also used the same value for all liveries.

I am at work now. Line I wrote , this evening I will upload the correct package.

Just try it out.


Edit : the correct package has been uploaded
