Hej,I bought your (famous) 737 NG after you had left the stupid registretion procedure.Your 737 became my most used plane in the FS2004.But now .........Everytime when I try to make a "flight", the plane rotates in the longitudinal axis to the left and explode.BEFORE I start the engines.Nearly everytime after 1 till 2 minutes when I am working with the FMC.I tried it on different airports (AddOn and Default) and with different PMDG 737 liverys.What is the prob?Jan (ESPC - sweden)P.S.I installed the SU1.1

JAn this is known problem when you use the APU...it has happened to me a number of times..simpl esolutionstart with engines on and NEVER turn on the APU..it works..APU=death!enjoyRob

Hmm-I always start with a cold and dark cockpit and then start the APUin the correct seuqence.Never had a problem - and I have had thisplane from the beginning.regards,David Pedder

I have never had a problem with the APU, and I always start from a Cold/Dark cockpit as well. Jeff

Yes I have to agree with the guys, I too always start with the APU and never have had this problem of explosions due to the APU. I hate to say this, but that is a little bad advice. I have had the PMDG737 from the start with all the updates and this has NEVER been a problem.I think what is causing this problem is either a bad set of contact points, or a weight and balance issue that got corrupted. I would suggest to delete your current configuration and re-install. Since you said that it happens on both default and add-on sceneries it it not scenery related.Bottomline however is that the APU does not cause any explosions.Bob Johnson

Thanks for your answers!But I think you all missunderstand me.It was no problem with the APU.After a couple of minutes got I a massive rotation to the left side ("bank angle over 180
