Hello and many thanks for introducing the F-16 in DCS!
Could I draw your attention in the sequence of the retraction of the wheels shown clearly in this HAF video at min 3.45 you can see that the rear wheels are closing just before the nose wheel which is opposite to the sequence is shown in the video WAGS has posted.
I am not sure if it is only the HAF block 50 vipers that have that sequence
many thanks
Tolis
