iNAV auto flight on Diatone 250 FPV drone.

I was looking for cheap, affordable, open source and easy to setup autopilot system with GPS feature on smaller drone racing size multirotor frame for portable aerial photography solution, few years ago i was on MultiWii Pro but the flight controller was way too big and heavy. Many years later all this tech stuff changed. At first going for Mini APM but not very good handling sensitive PID setup and way expensive to implement. Fortunately the new iNAV autopilot software which is a branched out from CLEANFLIGHT and BETAFLIGHT program offer great solution with GPS navigation capability especially on smaller drone such as racers size by using existing drone racing flight controller. So i purchased an affordable SP RACING F3 DELUXE flight controller board and mini GPS Ublox 7 to add to my existing classic DIATONE 250 quad racer and gutted out 1900KV brushless combo unit from my previous FPV600 project to build me a new mini auto pilot GPS driven 250 quadcopter. On this video just doing some simple test flight testing some vital feature what basic function INAV flight firmware can do on mini quadcopter. Take note i didn't put much effort tuning the PID which take lots of time to do it so i leave it stock setup, the flight overall is manageable even in heavy wind. For those have a mini quad racer you can try it out by adding extra GPS hardware for extra automated flight without burning hole in your pocket.
