it is flaps on the trailing edges. the inner ones act as flaps while the outer are ailerons. i have tried taking off with flaps on and off. off i get the result listed above, on i get a violent jump around 100 m/s and the plane blows up. i'll get a FAR display for you later if you want one, but won't be able to until this afternoon as i'm at work until then. Anyways, you are basically right about where the two centers are, except the COM is a bit further back. i tried to make sure the rear gear was very close to it. are you saying though that the COL needs to be very close to the COM? because currently that is not the case. I'm still fairly new to FAR mechanics, and i know having a COL far away from the COM in default is not a major issue. thanks for the help

can someone help me figure out what is wrong with this plane? I have tried everything: 1 engine, 2, 3, engines on the top, on the bottom, near the tail, near the front, slanted wings, high wings, low wings, v tail, cruciform tail, and pretty much everything else. landing gear is aligned with the absolute grid. yet i can't get a bit of lift. if i clear the runway, it goes into a very slow, inevitable descent no matter how hard i pull back on the stick. http://imgur.com/c4DAMmE.jpg
