-<note>build in progress</note>+<note important>This quadcopter was dismantled on 19.6.2018 after 28 flights. I don't suggest making a copy of this setup. It's too heavy and underpowered as a result even after swapping the separate camera and vtx to a 2-in-1 combo. The custom prop size is also a pain especially when the prop breaks so easily. See [[rc:lantian-l90|Lantian L90]] for a better alternative in the same size class.</note>

 +  - Turnigy nano-tech 450mAh 3S 65C is the suggested battery by Flex RC.
 +    * Not good in reality, produces low voltage warnings early in flight.
 +    * Use Turnigy nano-tech 850mAh 3S 45C instead, even if a little heavier.
 +  - The field of view of the camera is big enough not to require any uptilt.
 +  - VTX video quality is rather bad even when flown outdoors and doesn't appear to be directly related to throttle levels.
