I have following experience: when landing in latest Open Beta (1.5.3.52875) after touchdown in around 140kt, if I do not apply airbrakes, Mirage FBW is holding AOA 14 for aero braking. Once speed drops to 98kt, AOA begins oscilating between 12-17 AOA, but speed stays at 98 until airplane crashes at the RWYs end (without using wheel brakes). Engine is idle immediately after touchdown, but after slowing down to 98kt speed stops droping.
With speed brakes activated after touchdown, Mirage slows down and below 100kt, nose begins oscilating between 12-17 AOA, but speed continues to drop and around 70kt front wheel touches down. Without using wheel brakes airplane leaves RWYs end at about 40kt. I have been testing this at Mineralnye Vody airport, with 4000m long RWY.
In previous version (Open Alpha 2.0.2.52658 ), its possible to land in Groom Lake (3600m RWY) using aero braking (with or without airbrakes) and Mirage stops itself before the end of the RWY without using wheel brakes at all.
It seems in new OB version, aero braking is less effective. Wheel braking seem weaker as well, I feel that now it is a bit harder to stop the Mirage after landing. I have noticed as well, that on idle Mirage is moving forward very slowly, same as Su-25 do...
