Follow me as I attempt to build an fully autonomous flying craft (based off the movie The Terminator) called a Hunter Killer.
Part 5: More Parts On The Way.

I’ve ordered a few more parts which are needed for phase 1.
EDF Ducted Fan Unit 2.56 inch 6 Blade
This is a fantastic EDF unit, the look, size and specifications are perfect! One problem I see is the motor that I ordered has a shaft of 2.26mm which could pose a problem. But hey, we’ll resolve that problem when we need to.
Hitec HS-55 Micro Servo Motor
Servos will tilt the EDF units, 2 have been ordered. Another component that may cause an issue, this is due to the torque being rather low. But again we will have to do this by trial and error.
SFE Single Axis ±300°/s Gyro Breakout Board - LISY300AL
The gyro will allow the Axon micro controller to determine the angle of the HK which will keep the craft stable while hovering – which is actually more a phase two feature but it will be important to start work on this early..
Next testing, then construction… We’re well committed now!
