GPS Racer project is almost done. Last week I’ve assembled al the electronics I had and maidened it over the weekend with partial success.
Build is still missing FPV gear: RunCam Owl and VTX did not yet arrived so. Without them, final specification is:
- Frame: Realacc X6R
- Motors: Emax RS2205 2300KV
- ESC: FVT LittleBee 30A
- Propellers: Gemfan 6030
- Flight Controller: Airbot Omnibus F4 Pro with INAV 1.6
- PDB: Matek PDB-XT60
- RC link: FrSky X4R-SB with SmartPort over SmartPort inverter
- GPS: Beitian BN-880
I must admit: that tower in the front, while required for magnetometer to work properly, is one ugly piece of plastic. I really have a talent for building ugly looking UAVs and this is not an exception.
Since I had no FPV over the weekend yet, I was flying only GPS assisted modes. Must admit, that was fun. Position Hold and Altitude Hold was rock steady. Very little if none wobble on descend. But the biggest fun was high speed CRUISE and RTH. By high speed I mean 15m/s (54km/h). Seeing how UAV goes by itslef at 54km/h and then breaks hard to landing is little scary.
Unfortunately, I was unable to test waypoints navigation. GPS module (Beitian BN-880 that I just a few days ago called the best for INAV) died. Probable cause: voltage regulator burned. I have a spare, so this weekend second part of testing…
