This proposes to be the world’s smallest Drone (God I hate that bloody word), whatever it is I broke it.
After smacking it into a wall it had a remote control distance of about 30mm.
Here’s it in bits and some pictures of the insides, I eventually found the SMD part missing only by comparing it to another.
I bridged the gap and also extended the curled up antenna which really increases the control distance so much you need binoculars to fly it.
The screws from the bottom are smaller than ants.
The curled up antenna.
That part missing is 1mm long about 0.5mm wide
