Bonjour Olivier. I have found the same differences in three of my quads. I have an X210 racer running Betaflight. I just recently finally reflashed the ESCs and now fly with DSHOT600. Its amazing 🙂 Like a smooth extension of my eyes and mind.
I also have a Martian II and a Reptile500, running very different hardware but both flying iNAV1.8 firmware. Both need more tuning, but still obviously lack the performance and stability of Betaflight. The Reptile uses old DT750 motors though, which make it a heap more vibration prone than the ironically more stable Martian II.
Do you know the reason that iNAV does not feature better ESC and gyro performance? Is it a hardware limitation based on the capability of the FCs we use, considering the processors have to handle GPS data and navigate themselves at times as well as simply fly smoothly?
Happy flying man!
awesome comparison, inav was more smooth and betaflight was more robotic. is there any particular reason why you choose 2600kv instead of 2300kv. because you said you doesn’t like racing. I’m currently using emax rs2205 2300kv version because of wide range of prop selection. Bon Journee
Hi Oliver, nice comparison. Can you share the complete settings you used in INAV? Seems like we can optimize the “Racing” preset some more. Oh, and I’ve also noticed the yaw vibration issues with 2600kv motors on my quad. Must invest some time to figure them out.
This gives me hope for my 6″ Inav build witch at the moment flies like crap lol… Thanks for posting 🙂
