Where do you get heliport blueprints on mysims kingdom?

1) Get the Heliport Plans by earning a medal in a minigame. Some people get theirs from the Vegetable Game in Town Hall. I got mine from playing Tennis.

2) Take the plans to Torajiro the carpenter and give them to him using the gift icon.

3) Talk to Torajiro again and select the wrench icon to have him build things for you. Choose the Heliport option and have him build you as many Heliports as you have Heliport Markers (the ones you buy from the pilot that sit in your inventory).

4) Go to the places you want to have helicopter access to and place the Heliport Station buildings in each area. You cannot place Heliport Stations if you do not have Heliport Markers in your inventory. You will use up 1 Marker for each Station you place down.

5) You have to buy a bunch of Heliport Markers from the pilot in order to fulfill him anyway, so you might as well buy them now and get yourself all set up with lots of Heliport Stations.

6) Start flying! It's great when you can travel this fast! Saves a lot of time.
