Why does my shuttle rip-off have so much drag?

[The_Joe]

Im trying to make an SSTO and this was my starting point.  It carries a small mun lander.  I was planning to expand tanks and figure out what it needed to reach orbit but it's got more drag than I think it is supposed to?  Any suggestions?  Craft file: https://drive.google.com/file/d/1-6aYOiDFg2835wKpiv6XiH4yC7bBeXWp/view?usp=share_link

Ya got multiple things going on here.

First off, the shuttle sized parts got significantly more drag then the 1 size down parts, you can generally tell how much drag a part is going to have by the size of the connecting node, and shuttle parts got beefy and thicc nodes.

Second, all of the cargo bays are bugged. With the smaller sizes, you can put an aerodynamic nose cone inside of the cargo bay on either ends (as long as its not stitched together and is a single piece) but with this bigger one, you need a large cone which has tons of drag on its own.

Id suggest trying to take the cargo bay down by 1 size.

you could check my ssto pack to see how i get around drag if you want some pointers.
