See why everyone is crazy about this now RTF plane, the revised Dolphin from AtomRC, with INAV6 and DJI o3 on it. Link: http://bit.ly/3JI8pFA
Thanks AtomRC for supplying this unit here for the review!
Massive thanks to TJ for helping me with the external shots (don't miss that part starting at 10:22!!!!) check out his channel: ‪@dynashot1‬

Build was quick and easy!
servos, linkages, motor, ESC, FC and GPS were already installed
Wings and vtail needed to be glued on
prepared DJI O3 cable (long with plug for FC was supplied, other end open cables)
connect CRSF RX (on UART 2!)
printed a custom O3 lensmount for the little cutout just behind the nose
make sure o3 has enough cooling! Don't use rocksteady as this makes o3 hotter?
created a little air scoop to help the airflow https://www.thingiverse.com/thing:590...
installed a heatsink on the O3 (25x25mm)
Tip/correction: bending the cable like I did with the CRSF antenna is not recommended!
3d printed latches for securing the canopy https://bit.ly/3AoxRKA

TECH SPECS:
Wingspan: 845mm(33.2")
Length: 710mm(28")
Weight: 520gr with dji o3
Motor: 2306 1700kv
ESC: 30A with 5V/3A BEC seems to be strong enough to supply DJI O3
Servo: 2pcs 9g servo
Propeller recommend: 6~7 inch, incl. 70x40 (cw and ccw)
Batteries: 4s 1500-2200mah LIPO or 4sLiIon 3000 or 4000mah good cells (30-40amps)
CG on the "nobs" works fine, maybe use a slight bit forward

SOFTWARE - INAV 6: "horizon hawk"
it had INAV 5.1 preinstalled, with basic settings
if INAV configurator (use the correct version!) doesn't connect, use the ImpulseRC Driver fixer. It's still a valid tool - and GOLDEN!

INAV 6.RC3 (as of 11.3.2023)
firmware: ATOMRCF405NAVI
CRSF: UART2
GPS: UART4
DJI: UART5
FC has barometer!
all SETTINGS are here: http://bit.ly/3Fpu8zu
______________________________________________________
ESC: ATOMRC BLS 30A (input: 2~4S Lipo)
Continuous current: 30A / Max Current: 35A
Output: Built in 5V 3A BEC
ESC doesnt need calibration if you use DSHot 600
Set motor brake with BLHeliS config! (or reverse motor direction if you want to use other prop)
