Polikarpov I-16 Stalling?

[MadMel69]

Thanks for the info in these posts, I have only just got on the game and was enjoying it until this plane popped up.
I had wondered about altitude but had stalled quite low down, then considered too steep a climb, but still my engine died. I had used WEP but stopped. The 80% throttle limit will be tried tonight.
I tried to restart the engine with a fantastic dive, which resulted in a really quick death
