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:

If you're bouncing it means you're hitting too hard, full stop. The FM may influence it, but the #1 determinate is your vertical speed. 5ms is MAXIMUM. You should TRY to touchdown 1-2ms, or in general as gently as possible. Guaranteed you will not 'bounce' if you touchdown gently. It does seem to wobble a bit in the above video, but the gentler you touch, the better it will be. Also watch your weight. Most aircraft land with minimal fuel and stores.

exactly if she bounces, you're not gentle enough, which means sink rate is to high in the moment of touchdown. Even ironhands landing as he said himself is still on the rougher side


If you watch sour sink rate and your aoa there are no issues - at least in my case

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.

+1 on the sink rate (1-2m/sec); the final flare should take you there (no rhyme originally intended).

The MiG-29 is fairly easy and simple to land...

I don't think the problem is my technique. I land F-5E, Mig-21, and AV-8B, without a problem. There are two issues with Mig-29 PFM (both A & S). First is pitch control. I use X56, and my pitch curve for -29PFM is 40. Normally it is 25. So a pixel's worth of pitch deflection, as seen in on screen stick control, causes inordinate amount of pitch. Second is exaggerated bounce. There are two types of bad bounce. First is main gear bounce, due to excessive VV. Second, more insidious one, and one that does not make sense, is front gear bounce and rebounce, with each one picking up more energy, untill A/C is back in the air, despite throttle down to idle, and drogue chute out. Like Flubber from Disney.
