On your latest F4-E, mod/version, on landing approach your landing gear indicator is activated at 400 knots, once gear is down at same speed upon approaching runway at 340k loaded with missiles and fuel, at wheel touch down without aircraft wobbling as it some times prone to do if too slow., I can touch down rear wheels first at 320 knots , airbrake will give a sooth stop with no chute used at less than 270 knots. In my flanker 2.0 manual, depending on the aircraft approach speeds at 5k from airport 450 to 500k after making final run 50 meters height 280 to 270kts, and as slow as 250kts, depending on your sink rate /AOA you can damage landing gear. if the aircraft sinks too fast ( F4-E for me ) increase throttle. I am not questioning your expertise in making and flying excellent mods. Just letting you know that the 5 flight simulator manuals, Jane's USAF, 1999 Jane's WWII fighters, Israeli Air Force 1998, Flanker 2. 0 Lock on 2 manuals, show various landing speeds techniques depending on aircraft load outs and fuel when landing. They also state that landings can be as slow as 165Kts. I am no expert, only real pilots are, but the speeds work for me.
