Niki performs too well in the vertical, frankly there is no doubt of this anymore even pyro said a while back that there is something off in its verical climbing performance. I have outclimbed expertly flown P51s at 28k in a 75% fueled niki, so much so that I forced them to dive away as my closure rate would put them in my guns range.
Nikis retain E far too well for vertical manuovers after extremly hard turns and breaks. I speak from experience here lots and lots of both flying nikis and fighting them in G-10s, and have seen them keep with me in zoom climb even close unless I had tremendous initial speed advantage. A 109 G10 will outclimb a niki no doubt but the advantage is so minor due to nikis reluctance to stall in pure vericals as to give the 109 few options to attack the niki. The 109 will always stall before the niki in this situation, often I find myself flopping like a fish stalled on top of my zoom and the lower E state niki is still climbing and of curse spraying madly with its cannon. This is another issue that drives me nuts it seems that recoil isnt effective in slowing planes down in zoom climbs and causing them to stall. There is a recoil effect in autoclimb and level flight, but i have not noticed such an effect at all in zooms- the vsi keeps at 4000fpm plus all the way till stall when it suddenly drops- there is never a gradual decline caused by gun recoil. Nikis arent right, im no aerodynamics expert but it doesnt feel like the other planes in here. Im sorry if that isnt good enough for some of you but I can only speak from my extensive experience flying in and fighting vs the niki. Ive said this before and will reapeat in endlessly the niki roughly has the FM of the Janes WW2 Fighters Spit9, climbs turns at will, regains speed immediatly after stall, useless stalls etc etc- I flew WW2Fighters for online almost 2 Years on a dailiy basis and I swear they have damn simmilar FM. This is a shame on AH.
