Hello there !Another post from the same guy (I am flying a lot this bird those days)Using my MD11, I got an overspeed (thanks to the wind change and a faster speed given by ATC).Speed reverted to protection... afterwards, I made a direct to a point in my FMC using DIR page... and the plane started to go to right then left then right... between old set HDG and the FMC new heading...To go out of this surprising problem, I had to put plane on HDG SEL mode then do the direct again and put NAV mode back online.No other isue afterward anyway...Regards.

I use registered copy of FSUIPC to tame the MSFS weather. I set the change rate to 8 seconds per deg/kt change and I set the pressure/temp gradiants to half (FSX).

I think I do not made correctly my point... Overspeed is not hte problemAfter overspeed alert, AP mode changed as it should and came to protection... But NAV mode was s till activeI set back to FMS Speed when able and have to do a direct to a waypoint.Plane started to turn to make the direct but... rather than going to fly direct, it started to go to the point (on the left at this time) and when nearing the correct heading he goes back to the HDG like if I was setting "HDG SEL" then when at the HDG on the right he goes back to the NAV hdg and does that indefinitly...Seems to be a bug... I got an issue using HDG button as well... if you make more than 360

on a similar note, i noticed that while the MD11 is overspeeding the elevators will not return to neutral when the yoke is neutral. If you pull back the elevators lock in an up position and if you push all the way forward the elevators lock in the down position, turning off the LSAS seems to return things to normal

I have this problem occasionally as well, although I can't really remember if it's after an overspeed condition. Basically, after a while, the aircraft begins to waver left and right by about 1-2 nm left and right of track. Pretty much exactly what Francios is describing.I have a registered FSUPIC and it tames the weather changes for me, but this problem shows up occasionally still.Using MD-11 with the latest 1.10.0051 installed in FSX+SP1 (<- perhaps this is the problem?)Win XP SP2a

Not a SP1 on FSX issue because I use PMDG MD11 on FS9 ;)
