Do they sell scaled down FULL engines?
Literally the same with seals and everything.
I'm pretty much interested in learning the engine inside and out so preferably a kit that comes in parts and you build it back up.

So far, I only found this by Revell, but not sure how 1:1 it is when it comes down to parts.

Living on the 3rd floor of a dorm with minimal storage so can't buy a real engine lol
