Flanker vs F-15

yes Flankers have a switch which over rides the FBW limits, that's the only
way they can do the "Cobra" manuever. As I recall F-15s started out with
hydro controls with FBW as back up, then later models went fully fly by
wire.

The Su has a pull-through fuction on the fbw ISTR. Might be a factor?

Probably not since the the F-15C isn't FBW and only has an overload
warning function. You can over G a F-15C.

The F-15 started as conventional with conventional backup and an
analog FCS. It eventually went to a digital FCS, but not to FBW.

The E might be FBW, but the A-D aren't.

Or you can simply apply an extra 33lb of stick force.

That is a lot, the F/A-18 breaks out at 20 lbs.

Not true - you are confusing this with aoa feedback in the stick above
20 alpha -to get more g than the programmed limiter (usually 7.5) you
must engage the paddle switch, which will then give you 33% more g.

I am refering to the force required to move the stick. My F-18 (AV6) had a
swich on the left panel to cut out the FCS much like the MiG.

The stick moves to operate the cable actuated system control system.

Do you know the airplane at all, monkey sock?
