Propeller guards are not field replaceable therefore this is not a travel friendly drone. Neither is it business friendly if you are using it for your e.g real estate business. It needs to be sent back to DJI for guard replacement, therefore your business will have downtime. This was a HUGE mistake by DJI designers.

We understand your concern. The built-in propeller guard is lighter compared to separately installed guards, allowing for longer flight time. Also, thanks to the integrated body design, safety in scenarios like collisions and falls are higher. Please rest assured when using the drone.

Confirmed/verified: Ham File works and unblocks FCC in Avata 2. However, we still cannot change channels. But the most important thing is that we have the full speed and full power. There is also no manipulation of the software by an external application that could affect the warranty or Care.

As an avata 2 flyer in CE region I can confirm that the ham file does unlock full speed in manual mode.
Also my drone or goggles are fully up to date,

Same, it is still working. Hopefully with new firmwares they keep this functionality.

For anyone still looking around, thisVideo should explain that the ham file now is an insane buff and wether you are in CE or FCC areas the HAM fixes it all, unlocking higher max speed, custom channels and more channels.

I would like to be able to change the power on my Avata 2 but I'm afraid the ham file will result in a denial of DJI CARE-REFRESH service. Ideally, the class of drone would be selectable. Currently I find it dangerous to fly in manual mode. I found this out quite painfully yesterday when the drone had too little power to recover from a short dive.

The ham_config_support file is used by many for years on DJI FPV, Avata 1 and Air Units. I never heard of a denial of Care Refresh because of it.

Power is same just lower top speed?

no, max rpm of motor is less, so also less power.
