First 7" to join the fleet. All 3D printed parts were designed by myself EXCEPT for the air unit antenna. If you want any of these parts.. https://www.thingiverse.com/thing:4128701

2x 1300mAh CNHL Black batteries in parallel gives 8-12 minutes of battery depending on flying style. Plenty of time to do multi mile mountain bombing runs which is what this build will be used for.

UPDATE
As of March 2020 this build moved to crossfire because R9 is trash with multiple pilots.

UPDATE July 15th
Still flying like a champ. Soldered SMA pigtails into the air unit to eliminate the terrible mmcx connectors. Added a new antenna mount to the rear which puts the VTX antennas in a much better location. Also added a BN220 gps above the gopro mount. Locks 10+ sats fast, and keeps locked during flight.
