"I dunno about that. Have you seen Kirk's F-16 for FS2004? He modeled the arms and legs in there too, and it look GREAT. very smooth and realistic. but I agree with the above, it would be best to not be able to see the floor!" 
  
  
I don't know Kirk's F-16, but why not try this solution if it looks good and real. 
  
My main request is immersion and when I look now at an empty cockpit, after having played Lock-On, it doesn't work anymore, I feel it fake ! 
  
I can't really explain why, but, in Lock-On, I enjoy seeing the legs as if they were my legs, but if I imagine seing too the arms, I would say "hey, who is in my cockpit". 
  
In fact, I do like how the legs are modeled in the Lock-On cockpits and how only the upper part of the stick is visible, so no problem for me not to see the right arm. 
  
As a resume: 
  
No legs: a ghost is sitting in my cockpit 
Legs and arms: who's flying in my cockpit, it's not my arms? 
Only legs: I'm in my cockpit 
  
It's not really rational, I admit it, but I feel it this way ;) 
  
Cheers,
