BD1 "Chimera" - 2.2" 3D printable drone | analog / P1

Chimera is 2,2" freestyle cinewhoop type drone, for 3S batteries, with fully 3D printed construction
Chimera are able to carry light action camera, like osmo nano or insta360 go 3S
Weights:
~170-180g with analog / P1 video
~220-230g with analog / P1 video and small action cam with mount

It's not cheap project- don't do it because of lack of funds. Buying a ready frame will be cheaper than buying CF filaments

one battery for one 2-3 minutes flight. Make sure you have more than 1

project contains configuration for HD version with BZ- pin used as VTX power switch.

If you are building remotely:

choose analog OSD Protocol and type OSD_HD in custom defines, to build firmware with both- digital and analog OSD
In other options add Magnetometers, Position Hold and Altitude Hold

BD1 stands for "Bart's Design 1"
