@RailfanEthan good thinking,thanks for the idea

Well you're still gonna want to insert the wings, they can be small and hidden. SP physics are weird like that.

@AstleyIndustries good idea,i'll try that

@Kerbango I want to make it myself

You can use the gyros

@Kerbango good thinking,I'll try to find

@RailfanEthan what I mean is a flying wing without tailplane,the one that looks like Horten ho-229

Find one that works using the search function, and tear it apart, find out how it works.
Looking and exploring for yourself teaches you much better than someone just saying go do this this this

Insert verticle/tail wings into the actual wing to make it stable.
