Help with rear-propelled planes!

40.2k Awsomur  7.5 years ago

I can NEVER get planes with jet engines in the back to work. I try and it always fails. What could I be doing wrong? Any tips?

    In short, it's very complex and it takes perfect fine tuning. Thanks for your help. @ChiChiWerx

    Yeah...with heavy jet engines, you need to make sure you put fuel or ballast forward to get the CoM (red line) ahead of the CoL (blue line). In SP, the engines are a small assembly; however, in most aircraft, even fighters, the lighter tailpipe or afterburner section is much longer, so the engine's CoM is further forward than what it is in SP builds, moving the total CoM further to the rear than what it is in real life.

    @Awsomur Center of mass should be ahead of the center of lift

    It's behind. Should it be ahead? @EternalDarkness

    It shoots straight into to sky and flips out of control. I think it has something to do with what @EternalDarkeness said about the CoM and CoL. Thanks for you help. @DisferGoatz

    Engines are heavy. Check if your CoM is ahead of the CoL.

    What happens when you test it to fly?
