Oh,ok.Thanks.

To keep the wings low and have it not go up, change the angle the wings are angled at and move the CoM around @FastDan

Thanks for the advice dude!I didn't add Windows cause the style I wanted wouldn't work.I put the wings high to make it not veer upwards.@Mustang51

I can see potential in this but a fair bit has to change. I would put the wings much further back and lower on the aircraft (look at pictures of airliners for reference or even take a look at other peoples planes). I would also add windows! Details such as windows make a build feel much more complete. The cockpit could also do with some work but airliner cockpits aren’t that easy. What I do really like about the post is the door you added and the engines!
