I-153: cheap or not?

LOL thank you. You just disproved your statement ("Actually.. both turn radius and rate of turn have nothing to do with lift, but a lot with speed."), and reinforced my argument that the 153 can turn tighter because it has more lift due to having 2 wings instead of 1.


EDIT: thus, making it a cheap plane to whore in online matches. I rest my case

Agreed, that statement was incorrect in retrospect. Again, the general rule to aviation forces is: everything affects everything. Conclusion: you, Soviet and me were all right: you need low speed for the best turn, and high lift to maintain it.

P.S.: The formula goes for every plane, you'll just have to check if the airspeed and bank angle used can actually be maintained in a constant non-accelerated flight. E.g. you can't say 'A Spitfire has a turn radius of 14 ft if you fill in v = 30kt and bank angle = 80 degrees', because the Spit can't fly 30 kts with a bank angle of 80 degrees while maintaining altitude and a coordinated turn.
The constant was for conversion so the answers would be in knots and feet.
