I was almost yelling at the screen at the point where he was explaining how he manually had to adjust the pitch of the propeller. That’s where a simple circuit and actuator would have excelled.

I haven’t seen the original video, but my guess is that the creator of Blackbird wanted the car to be free of all electronics, to dispel any claims that it could only be done with a motor.
