>>>toy helicopter gyros. Yes, but…
I was down the beach the other day and watched someone using FPV glasses and a waterproof quadcopter, launch it, fly it over the sea and then track a surfer along a wave. The copter then was flown back to the beach where it hovered, close to motionless, over the beach. The operator then removed the glasses, turned around to see where the thing was flying and picked it up out of the air. There are other FPV aircraft systems which have a "panic" function. If the system loses the signal from the controller, it returns the aircraft to a pre-designated spot and it either circles or hovers until the control signal is picked up again. From memory, the entire system of inertial guidance platform, transmitter, receiver, glasses etc was under $400. Toys… well yes, buy folk like NASA would have paid an awful lot of money 30 years ago for something a fraction this sophisticated.
