I have not flown much in the past year or so due to real life issues, but, personally, I've always had good results with the F4U series. If you and are not afraid of carrying 100% fuel and drop tanks, and if you are willing to take the time to climb to 25-28k and utilize good fuel and engine management, and if you have the patience to track bombers on radar to put yourself on an interception course, I think you will be surprised with the way the F4U handles at high altitude and the results you can obtain with patience and cunning. The reason I fly the F4U series almost exclusively is because of it's versatility as a fighter, fighter-bomber, bomber hunter, and add in the fact that it can take off and land from aircraft carriers, well, it just makes the aircraft one of the most rounded and challenging aircraft in the plane-set.
Caldera offers several choices for bomber hunting and I do not disagree with him; but I will point out that each aircraft requires a different set of skills to fly well against bombers...that's a lot of skills to learn, and none of these aircraft are available on aircraft carriers!
109G-2 and later (gondolas preferred)
110G with light gun package (no rockets)
190
P-47
Mosquito
La-7
410 with 30mm
152
P-51
Tempest
Spit 8, 9, 14, 16
P-38
DrBone1 points out that patience is not in his game bag when it comes to bombers and he prefers to resort to his perk pool and he wants more than a single set of bombers to make it worth his while...and that is fine, also.
If you have the patience to go that high you are a lot better then me.
If they ain't below 10k I ain't going for them Hehe! honestly you are wasting more time climbing for those buffs when you can shoot down more than 10 planes in the time it took you to climb to that 1 set of Buffs, now if you are speaking if there are multiple sets inb and early warning about 3 sectors out I may roll a 262.
Just my whole look on the Buff hunting deal too much time for little reward. salute
There are many options available to do the job, but I challenge you to learn a single aircraft that can do them all, the F4U!
Oh! Just as a side note and if you are interested, I set all of my guns' convergence to 275 and have learned to fly with it set there. I have learned that there is no "magic" convergence whether fighting at 25k, or on the deck, and whether using 50 cals, or 20mm hispanos, the end result is the same.
Good luck, and good hunting!
