Ah, finally landed right, very funny! They actually seem to have found the problem for the third incident. The O-ring that got loose and blocked the hydralics was actually for the nosegear and thus smaller than the correct one for a main gear.
I've been trying to fly the authentic Cardinal model I got for FSX but the joystick is really twitchy, or rather, it acts twitchy when looking at the virtual cockpit controls, and as usual it seems it reaches maximum deflection clearly before the joystick does.
