The Scarplane is a type of transportation found only on Otomai Island. As the names suggests, players are able to ride tamed Scaraleafs to various parts of the island. Anyone is able to use the Scarplanes - but first they must complete the Quest needed to use that particular station. It does not cost any Kamas to use them. You only need to complete the Quest for the Scarplane stations that you wish to fly from - it is possible to fly to the other stations you haven't completed.
