womenfly2, I feel your pain. I checked out the ROF forum on this topic. One of the devs stated that the DVII does tend to be twitchy with nose bobbing (which is a reflection of the real thing.) Now, the Spad is supposed to be more stable, especially when firing the MGs. Here's what I'm finding: The DVII is harder to control in gun runs and bobs up and down, conversely, I find the Spad in gun runs moves from side to side.
I realize the devs are trying to give us a realistic sim, but when your enemy is not having the same problem in a 1 on 1, the dogfight can go on a long time even if you ARE a good combat pilot.
I've flown the 1vs1 Russian Roulette mission around a dozen times. I've played around with my gun convergence range. In the ROF settings under the Camera Tab I've unchecked "Shaky Camera." These changes have helped somewhat. In the 1vs1 engagements I've gotten better. In one particular flight I shot down five of them in succession as they respawned, before being downed myself. In 1vs1 there doesn't seem to be much variance in the enemy AI.
On the ROF forum the dev stated that "you need to have a light touch on the stick and slow the plane down when firing your guns" he also stated "that it was easier said than done." Well, no kidding! When you're in a dogfight and constantly trying to dive, climb and out-turn your opponent its' a bit hard to "keep a light touch." Short MG burst also help when you've finally got your enemy in your sights, too.
As I said, this twitchy thing to the extreme needs to be addressed in a patch, or at least give those of us that aren't fanatic hardcore simmers an option to make the Combat Gun-Run FM more stable to our personal preference.
