So I just recently got MSFS 2020 have just been having fun checking out the scenery. I really want to fly the F/A-18 but every time I do I have problems with HSEL mode of the AP and for some reason the plane will just turn randomly for no reason so I cant maintain a proper heading. Is this a bug with the plane or am I doing something wrong? I know how to fly the F/A-18 since I have the VRS one in P3D so I think it's a glitch more than anything.
Also,how do I get the AP on the CJ4 to fly the path I have set in the FMC? I've got the the basics down and get it to hold a specific heading but I don't see a NAV or LNAV button.
Thanks
