Hi Raz!
One of the best advice I like to give to people who RP flying machine pilots is to use the /mountspecial wherever you’re about to dismount, this little trick makes the gyro shut off and land. Regarding the pilot gergo there isn’t any particular words used by gnomish pilots, aside from the stereotypical codenames.
My character isn’t an expert but he knows how to pilot a Flying Machine. I don’t really emote much when mounting but sometimes, if I’m required to transport something extremely heavy, I like to emote taking out a rope and tie the cargo to the skids at the bottom.
Oh and if you’re interested in joining a guild suitable for your character, consider joining my guild: Assemblage of Uld, all of us are flying machine pilots! I’ve been in this guild for a while and it’s incredibly active and involved server-wide, generating and attending RP events multiple times a week. We’re a group of dwarves and gnomes who seek titanic artifacts and relics, check us out!
