Octocopter makes perfect sense. Everyone understands immediately what it means, and that's the only purpose of language: to convey ideas. It should be clear, which this is, and concise, which this is.
Fidelity to ancient Greek is not, and should not, be a goal for English.
Comments
Counterpoint: -copter is a perfectly cromulent suffix. https://en.wiktionary.org/wiki/-copter
gyrocopter, helicopter, quadcopter, hexacopter, octocopter, parcelcopter, and—most famously—
roflcopter, https://en.wiktionary.org/wiki/roflcopter#/media/File:Roflco...
They all have their own dictionary entries.

Great examples. The English lexicon is continuously embiggened by the adoption and expansion of terms.
9/10, missed opportunity for "cromulent terms" at the end there.
The reference in the parent comment was already suitably frabjous.
