You need a special add-on for the fly-cam one to add TX controlled movement or triggering.

However this is inexpensive.

Since you are just starting out, the FlyCamOne is the easiest and one of the cheapest ways to go.

You may find that after taking video a few times, you will not be that interested in this, so you will also have saved the cost of a more expensive system or a downlink type setup.

The FlyCamOne is light enough to use in about any plane. There are also headband holders for it, so you can record video while doing active sports, such as biking, skydiving, bungee jumping, etc.
