Yeah. The word doesn't break down as "heli-copter." It comes from Greek "helico" (spiral) and "pteron" (wing). The correct split is "helico-pter" — a spiral wing. Which means helicopter and pterodactyl share the same root. And "heliport" isn't a helicopter port. It's technically a spiral place. None of this changes anything. You'll still say "heli-copter." But it will sound different in your head now. Bet you won't unsee that now!
