Flankers' flaps

Why does the '27 only have flaps on it's wings?

[Black_Hawk]

No, I meant why doesn't it have ailerons on its' wings; the only moving surfaces on the wings are the flaps (and the leading edge flaps).

Those are called "flaperons" and worked as both flaps and ailerons.

Like an F-16 do :)

Last I looked, it had ailerons. Flaps too.

The basic Su-27 has not. It's derivatives (like Su-33, Su-30MK) have them.

But the SU-33 flaps are only a single stage full on/off? I could have sworn someone said the logic for removing the 2-stage way back when was because it had "flaperons", but the splash screen photo (loading) for the 33 certainly does not support that.

Yup, once we did have 2 stage flaps...

I just wanted to know if the flaperons were better then the regular ailerons in terms of agility... But in Wikipedia it says that it's to reduce the weight and complexity of the a/c wings.

Ya... There is also what is called "drooping alierons." This is seen in the F/A-18 and (I think) on the Su-33. The ailerons actually "droop" down about 10 degees when the flapes are extended to help create extra lift and extra flap area. the ailerons are still operable, but are just pointed down a bit more.
