New Fulcrum A PFM is very susceptible to PIO and excessive bounce on landing.

Be aware of slat behavior, deploy at,roughly 10 degrees AoA but stay on until 7 degrees. Keep approach speed over the fence 300kpm and no less than 250kmh at touchdown

Slats are automatically controlled. There is no pilot directed slat deployment. Perhaps you meant flaps. I deploy FlapsDown at 400 and FlapsLanding at 330, and TD with 270 IAS. But now Mig-29 bounces a lot, PITCH is extremely sensitive and prone to PIO. I adjusted my Pitch axis curve to 45 from 25, and it is still very sensitive.

I believe they deploy at 7-8 and retract at 5 degrees.

Yes. I'm talking about the sim. But, then again, I'm only going by when the cockpit indicator light turns on and off. Haven't checked the external view to see if it coincides.

And, so, they don't coincide. While the cockpit indicator illuminates as soon as the slats begin to extend (at around 9°), it doesn't extinguish until they completely retract. They begin to retract at 7° as the manual indicates.

Thats all good and fine, regarding slats programme. Still does not help me to not bounce like Flubber when my main touches runway.
AOA 10-11
IAS 290kph at threshhold 270kph at T/D
Stores: empty or 2X R-73 on outer pylons
Fuel: 500-1000 kg TTL

And what's you're sink rate at the point of contact? It's too high, whatever it is. But, you're right, she will bounce. It's a little known fact that the Russians incorporated rubber technology into the aircraft to lower the RCS.

Anyway, here's a track that may or may not help. It's not the smoothest of landings. Made with the latest update. Ignore the first minute or so where I was trying to figure out what my dog wanted.

EDIT: Here's a short video from the track (in case it doesn't play back correctly) focusing on the HUD, VVI, and AoA Indicator:

use trim on landing... i use thumb rule of having trim nose up in approach so that distance number on hud equals my touch down. Then do not exceed AOA 11 at touch down and watch your variometer not exceeding 5m/s.
