what he said, and make it fast passes.
Actually.......the best at this was Knoxxy who has an amazing inbuilt gyroscope, cos having watched him, he is not a nice man to have shooting at your bomber
Try some different planes youself too, and come up underneath occassionally and aim at wing roots. A Hurricane Mk2 C is a 4x20 mm canon monster, but a Hurrican Mk2 B has 12 .303 machine guns, and god as they sound, the 4 canons does it for me,
Try the uber Yak 9 K which has a single 45 mm canon firing through through the propellor hub, and whilst the recoil is horrific the damage is amazing
then try a fast drop and gentle pull out with a FW 190 A9.....this has so much hitting power, and is so fast that the convergance for your guns has to be right out at 400 or 500 metres, cos ytou'll close on the raget so fast you'll be past in a second.
And lastly.....and for the most fun....try an I-153 with Rockets under the wings,
Set the rockets to explode at 5 seconds even if they dont hit anything, then creep up on the bombers from where ever is safe (very low behind?) AND let then ave a few well positioned, very far in front shots.
If you get the rockets to explode NEAR the bomber it WILL die
Lastly......do the honourable thing, grab an IL-2 3M and slowly close from nehind and then let it have both 37 mm canons AND whatever else you're carrying...including geoing over head with AJ-2 cassettes and littering the little monsters on top of the bomber
There is NO game as good or as hard as this
