Sparks,
The short answer is no. If that was the case the physics of the flight model would change on different speed PCs, and the end result would be rather obvious. The only real issue is the relative latency of the connections. The more latency in the connection, the more the difference in time between when he does something and when you see it. However, the delay is normally pretty constant, so the other guy follows the laws of physics and the flight model, you just see the results a half second later.
The only thing that throws a wrench into the works is packet loss or a widly varying latency. You'll know it when this happens, because the enemy plane will obviously warp. Not much can be done about that, it's the nature of the beast, however the poor fellow with the bad connect should be seeing everybody warp, so he'll normally have to correct the problem or be unable to shoot anything.
