First the M2 .50 cal that most wwII US aircraft where fitted with is a browning m2 .50cal just as with colt guns being produced by browning (and general motors who made the m16a1 I was first issued). but the m2 50cal is still in use today and it is typically a browning even from day 1 (most of the early heavy MG's where brownings). The USN and USMC wanted the F4u's F6fs equipted with 20mm to help knock a kamakazi down faster. infact they put bigger AA gusn on the ships for just this reason in the later part of the war. the hispano had a problem in ETO at high alt due to extreme cold. the south and central didn't suffer this as bad due to lower flights and warmer climate. this is one reason the 38 started going more to the PTO and less to the ETO. The USAF put 20mm hispano's in the p51H for operation olympic (invasion of mainland japan). for the same perpose as the USN and USMC to stop suicide kamakazi's dead before a dead pilot in a nearly destroyed aircraft could coast into his target inflicing massive casualties and dammage.
The best solution to the f4u1c is for people to stop crying about it. all of the big gun planes have a problem low ammo. if you spray and pray your lucky to get a kill in them. you need to have good acuracy and make your shots count cuase you don't have alot of ammo. 50cals are effective at killing most planes. I wouldn't tank hunt, assualt hangers or go buff busting with them but they are great for clearing AAA with there lazer like preformance and for cutting another fighter to shreds. wait till the p51h ki-84 ki-100 ki-61 spit ix all get here. hell you thing f4u1c's are bad wait till you get hit with a stuka or airocobra and their big guns. I can't wait for some of the early war stuff myself the ju-87 stuka, the p-39 airocobra, the p-40 warhawk (kittyhawk), the huricane, the f4f wildcat, the ki-34 oscar, the a6m2 zero, the p51b, and the swordfish.
I mean realistically the f4u1c and f3u1d are perty much the same plane. maight as well just call it an f4u with the option of 4 20mm, 2 20mm and 2 50cals, 4 50cals, and 6 50cals. I bet there would be alot less whining.

Iam ammazed theres more crying about the f4u1c as there is a n1k2-j. the n1k2j is absolutely evil in its leathality with ammo options of 400/400 and 400/500 for it's 4 20mm type 99 cannons. It turns and climbs better then a f4u holds it's e better and is almost as fast. personally the most scarry thing for me is a high 109 or 190. usually the 109 and 190 pilots have been around longer have more skill (specially the 190 guys) they know how to use their alt and E and have some of the most leathal guns in AH (30mm). add the frank jack and tony to the japanese plane set and the f4u drivers have to fly in groups and use tactics beyond the head on.
the head on that brings me to another point of why people cry about the f4u1c, they try with thier 50cals and 303s to drop a chog in pure straight head on. guess what he's gunna win. your really want to mess mr head on chog drivers day up... avoid the head on. typically a head on is a 50/50 deal any way. you have the colision as a factor as well as the guns. i bet more then 75% off all succesfull head ons end in both players loosing. the best way to even attempt a head on is in a off angle rather then straight in. namely cuase he has less of chance to get you and even if you miss or don't kill him with a light pull on the stick your right on his six.
The solution to the chog is simple. if you don't like it don't fly it. Don't get into head ons with it unless your in a fw190a8 and stil then its the same thing 50/50 with a colision factor to boot. force it to overhsoot you in the head on leaving him infront, under, or infront and under you. Use your planes strengths against his weaknesses, and stay off his nose get on his tail. killing the f4u1c is no difrent then killling a f4u1d.
personally I love the f4u1c and d. lately Ive been spending more time in the n1k2-j p51d 109g10 and bombers. why becuase there already to many people flying the f4u iam better in a n1k2 and I want to try more aircraft while not ading to the whining about the f4u1c. I don't want it perked and wish peopl ewould save it for assualt or buff busting.
theres nothing funner then killing a f4 who is trying to Head on shoot you. I avoid the Head on by rocking my plane back and forth on the way to the merge slightly diving under him before he gets within gun range i nose my plane down then up rolling around him and out of his gun solution. then I roll over going over the top in a shallow immelman or high yo-yo puting me above and behind him. If he has to much speed I just press him and as he tries again and agian eventually he ends with to choices run or continue and die. If he has alot fo alt on you remember he has to come down to kill you. force him lower and lower if he does get lucky he will be so low one of your buddies will surely get him. but avoid the head on with him and try to get him to blow his alt and E the f4u doesn't do so hot slow low with no E. It works great with spits yaks n1k2s 109s 202s 205s and the zeke (remember the zeke is slow so keep that in account) hell i bet even a good f6f driver can do it.
