Draco does not currently ship with a transmitter - you will need to purchase one seperately. The reason for this decision was to keep the cost down to the consumer who may already have a transmitter to hand. In the future, we will be offering bundles which will include a transmitter with Draco. At this time, we have no ETA on when this will be.
In the mean time, check out our supported list of transmitters which will work with Draco.
