Tyrannis,
first of all, its a great little bird, good choice in the early war.
Its pretty fast in the EW standards, also its climb rate is great, even when compared to some LW monsters. But its weak guns give you trouble when BnZing.
It can turn well, as long as it has speed. The stall speed/cornering speed is high, you will have trouble keep your flaps open, and they arent the best. Its a stabile plane tho, you can try bravely in the vertical reversals, it wont let you in trouble.
Against hurricanes, the best use is the rolling scissors. The hurries have very poor flaps. Same against the spit1, it has better flaps, but try to force the spit into a negative G maneuver, and the fight is yours. P39s are easy meat if you can catch them, same with the 190a5. Against p40s, f4fs, you can scissor against a less well trained pilot, but basically go to the vertical and rope them. Flat turn is acceptable against the f4f too, it doesnt have the power to get around quick once it deployed its flaps. Brews will be really hard nuts while your guns are weak and you wont be able to hang on their six long enough to fill them with lead.
One thing, leave the 7.7mm lil mgs at the hangar. They are useless.
Best luck with this beauty.
