What are the sustained turn rates of the MiG29, Su27 and J10?
Not a simple number I fear.
The answer will depend on weight, config, power, height and IMN/IAS. The number may be surprisingly small if all the conditions really are sustained.
I remember Victor Pugachev arrving at Paris in 1989 in a clean Su27 and doing a prolonged yank through 360 deg in the circuit in a tad under 10 secs which had a few people stupified. But I am sure it was not sustained.
Given that for good truly sustained g you need to have a modest induced drag (comes with a high aspect ratio) plus all the poke you can muster then I would guess that the order of merit for the aircraft you mention is likely to be 27, 29, 10.
