Learjet bounce and Jet drift

    It has to do with the trailing suspension struts, when they are fully extended the "knee" is a bit too stiff right now and doesn't move aft as easily as it should when the wheels are not yet rotating. This needs more fine tuning of this particular landing gear setup.

    i hope this will be fine tuned soon it's the same with 787 nose gear & few smaller aircrafts like the cessna. it needs to be damped way more than what it currently is having a bad landing after a really long flight just ruins it for me & might as well for some other users, I hope this is prioritised.

    also some fighter jets and even commercial jets like to drift to the left/right either while takeoff or landing what could that be?

    Changed the title of the thread from “Learjet bounce” to “Learjet bounce and Jet drift”.

    Jan if you are adjusting oleos could you make the P-38 nose gear a bit softer and the main gear stiffer and possibly 'pump up' the main gear oleos and let down the nose gear just a little. The P-38 is very bouncy and the nose gear consistently launches it up again (even with greaser landings, which are exceptionally difficult).

    If you have the P-38 folders open the roll instability at 100 mph could be toned down please,

    I hope you regard this as thread relevant and really hope you are in the mood to tackle the P-38 again.

    Thanks again for your dedication to keeping us all happy.

    (Edited. Initially tried with the default empty weight!)

    Could the F-15 main gear (or landing behaviour) also be looked at, perhaps when you are working on the Learjet. It does not seem to properly respond to a landing contact.

    I did one particular 300-400 feet per minute rate of descent flare for landing, a main gear only ‘greaser’ and the F-15 just soared back up with no aircraft pitch change. The torque links and oleos barely compressed on touching down, after a fairly hard bounce the F-15 soared up a second time and again the oleos had only compressed very slightly, only really doing so on the third and final arrival.

    A strict 300 fpm ‘greaser’ also bounced with almost no oleo compression. The oleos did compress with a more firm arrival but the F-15 still bounced back into the air. The simulation main gears seem to be hard.

    (Small Planes’ mod) Battery saver low power mode setting off and on. No difference seen.

    (Edited. I noticed the airliner early take off at default empty weight comments, I had not changed the freshly downloaded F-15 default 100% empty fuel and loads. At maximum (available in the sim) landing weight it looked a lot more normal but the F-15 still bounced consistently, apart from with one exceptional, sustained 100 fpm flare ultra gentle landing).
