Lag times and arena population is one of the biggest issues in my opinion.
As I fly EU timezone, there are days when I fly between 5 and 9 pm, I hit quite well with the 30 mm. Yet, after 10 pm, or, when arena tops about 200 people, the issues start stacking up.
Strange enough, as soon as arenas top about 300 it feels getting better?!
But that is my personal view.
Not only in a dogfight but also versus Lancasters or any other form of 4 engine buff.
When I see 3 to 5 big splashes on a rudder of a Lancaster or below the cockpit I expect some damage.
When I want to send film to Skuzzy, is it okay I have watched it first or does it render the film useless?
Most important things to me regarding the 30 mm:
I. Try not to fire simultaniously 30 mm / 12.7 mm, except on bombers
II. Learn the grizz way. It just works.
III. Analyse your shooting on film, very slow motion, check the range when you open fire. Does it fit with your convergence?
IV. Tracers off. To me it works as you try to learn the gun and the plane and don't do erratic stuff because you see your tracers all over the place.
V. Stick with the gun!!! One day in WW I arena and my 30 mm aim ( if I have any ) is absent for 2 weeks. A day in a Dora cost me a week. It's that bad.......
VI. Unload your plane! Let the engine do the work to pull the lead you need.
VII. Be patient and get close. Really close. When you take damage due to your own round exploding is just about right. I like to get within 200 yds or less, preferably at speeds that allow flaps.
Carry on.
