I've been playing KSP for a while but really haven't tried hard with spaceplanes. But I have made some awesome planes. And really the problem I'm seeing now is that they keep bouncing when SAS is on. Is that due to the center of mass fighting the lift or vise versa? or is it just KSP mechanics. It's probably just my design or something. Can anybody shed some light on how to fix it? I do have FAR installed and some common part packs.

How did you get it to fire? I've tried everything

Yeah im having the same issue. I dont know what im doing wrong :[
