IMHO the cockpit views towards the rear are decent, but not great, the heavy framing around the rear of the cockpit limits your vision, this was alleviated some what a couple updates ago by allowing more forward head travel, but maintaining SA is more challenging than a lot of other planes. You may be able to get some angles vs the SpitV early in the fight because the P-39D is actually pretty good at shedding massive amounts of E but once the E is gone I would be surprised if the Spit didn't just power around and get behind you. I also think the 30mm tater chucker on the K4 is a far more desirable weapon because it has a much higher ROF, the difference in damage between a 30 and 37mm round hit is irrelevant against most other fighters and under the current damage system 1 round of either on a heavy bomber isn't likely to cause catastrophic damage in either case the better ROF of the LW cannon far outweighs the larger caliber of the U.S. gun.
i havent had much problem with cocpit view, the only times i do is trying to look out the side car door windows. i absolutly love the p39's gunsight tho. i think its the best gunsight ingame and would put it in all my planes if i could, its just so clear un un obstructed. plus the cocpit design i love aswell.
i have outturned a few spit1's (and a hurr iic once) in EW, but me saying a p39 can outturn a spit comes from a documentary on the p39 i saw. where they stated the british analyzed that the p39 could easily outturn a spitfire, but couldnt outclimb it or fight good in a vertical. therefore the british went with the spitfire instead of the p39. plus both the D and Q models are pretty good at withstanding deep dives and still handle pretty well at high speeds. and lets not forget the p39 is a very rugged and reliable aircraft. she can take hits pretty well. (taters includeD) i have no proof of it, but a year ago i was in a p39Q in MW, got into a DF with a hurr IID, took a 40mm round right to the wing. nocked my guns out in that wing and gave me a fuel leak, but the wing stayed on and i ended up wining the fight.
im not saying at all that the p39 is an uber plane, it can be outperformed by alot of LW fighters, im just saying it doesnt at all desire the bad rep it has. it can be deadly in a furball, and most people underestimate it, which is a fatal mistake.
its deadliest in EW and MW. and can still be a strong contender in LW under the right conditions.
