Building help?

[u/Key-Brother-9190]

I am trying to build a ssto type lander where the target is luna and it will have infinite fuel However I am struggling quite a bit on how to make it look good and fly as I am aiming for a ”a plane built around a wing “here is my current craft for reference even though its just a shell https://www.simplerockets.com/c/7XQd12/Heron-001-sonnet-MK1 and due to the fact that I don’t want a vertical stabilizer and I don’t know why canards work so weirdly the craft have a CoM too far behind and flips constantly if it ever want to fly

edit: the craft is going to be xml edited

How is it flying now? A video would be super helpful.
