It seems really a new improvement in micro quad with these new tiny brushless 2S quads from BETAFPV.

So BETAFPV is provided 2 frames here, the 65X for indoor flight, and the 75X for outdoor flight.

The specs of the two quads are really the same, and the only difference seems to be the size of the frame and the motors/propellers.

For the 65X:
Weight: 26g (without battery)
Motors: 0802 17500KV with connector
Props: 31mm 4-blades props, 1.0mm shaft hole
Camera tilt angle: 35 degree

For the 75X:
Weight: 41g (without battery)
Motors: 1103 11000KV with connector
Props: 40mm 4-blades props, 1.5mm shaft hole
