What do the Драконы look like?

I don't know where Ты got the impression of six-limbed creatures from, but the Драконы are exactly as they appear on the cover of the Книги - if that is the way they were illustrated on the cover, then that is the best representation that we glean from these books.

I believe the Комментарий referring to whether the Драконы have 4 или 6 limbs is including the wings. I believe Pern Драконы have 4 legs and 2 wings. I also believe, although I might be wrong, that they are not reptiles, as I don't remember seeing anything about them having scales. I believe they have hides, another name for skin, like cattle and deer have, although referring to dragons, I may be wrong.
