The arrival of the DJI O4 video system that weighs only 10 gm means high quality video has become available for small indoor drones.  The DJI O4 is also called DJI O4 lite to distinguish it from the heavier DJI O4 PRO video system. Note that HD Zero also has a high quality video system for small whoop drones.

The 1S Meteor75 1S drone is smaller and lighter than 2S drones, and is easier to fly in tight indoor spaces.

OTHER DRONES  ... not recommended for indoors

HAPPYMODEL MOBULA7  O4 2S racing drone
review By Kim: https://www.youtube.com/watch?v=tiSsAEWvXOQ
Arrived on Feb26. 

See this review Squadding Quads  https://www.youtube.com/watch?v=MX4c1OggGQA&t=251s
prop: HQPROP 45MMX3 tri-blade propellers(4cw+4ccw)
Albert Kim    https://www.youtube.com/watch?v=tiSsAEWvXOQ
Camera angle: see 8m10s on Burns vid, https://www.youtube.com/watch?v=BHSYllLw35g
This drone has the camera pointed up at a high angle, suitable for racing; the angle cannot be altered and makes it unsuitable for indoor or slow flight.

I was looking at the mobula 7, so it's good to hear that it's not really suitable for indoor/slow flight before I bought one, thanks!
