What do I need to power up an EDF engine? [on hold]

An EDF is an electric ducted fan, so I assume you're not interested in the fans powered by internal combustion engines (or actual turbines).

Você vai precisar de:

1. an ESC (electronic speed controller) that is rated for at least the maximum current and voltage of the motor in the EDF.
2. a battery that can provide that current and voltage.
3. something to provide a throttle signal to the ESC. Usually this is a transmitter and receiver, but for bench-testing a simple, cheap option is a servo tester.
4. a charger for the battery. This must be able to match the battery chemistry, voltage and capacity (they normally handle a range)
5. if the charger isn't mains powered, it will need a power supply.

There are loads of on-line shops for all this.
