concvergence is overrated in american planes.
say you are flying a 109G 1x202x13mm then convergence IS important because your small, concentrated firepower needs to get where it needs to.
First thing i noticed was around 1:00 to 1:03 - wasting a lot of ammo.
P-40 C has six guns, yours has two different gun types and they are located in 3 different spots.
using convergence to get the Bullets on target is like shooting a .303s held in each hand, and shooting a.50 off the top of your head.
... nischt possibeul.
The yanks use shotguns a lot. Your P-40 is a Flying shotgun. as is a Mustang, a Thud...
do not approach from behind, with the target having a small area.
come in from below, and pull the trigger when you can not miss - only then will the 4x.303s do the job.
sniping with a shotgun aint fun. Ram the barrel down his
nose exhaust pipe before even thinking of the trigger.
check out around 0:40... you banked left and had the reflex to stay way below them, keep them well visible in the sunlight.
but you didnt... you were greedy to get close - and stayed in their fire arc.
at 1.17, after the first pass you dove - out of range. good.
but then popped up and seemed to have resumed to fire from their 6.
1.26 , yea, that's more like it. distance is good, now the approach angle...
a bit nervous? knowing the cameras are rolling?
5.25: much better i thnk, but the camera does not let me see vthe Kate. still think you did good.
keep it up!
