Avata improvements / hacks?

Hi, this is a shooting the breeze question, I was wondering what improvements or hacks were available for the Avata?

I’m aware of the FCC hack (create an empty file, without an extension called " ham_cfg_support ", and place it in on the SD card within the goggles in the root directory).

I was just wondering what else was available?

(I’m presently trying the Master Airscrew 3 blade props, and they do seem quieter / less whine at distance… but its very subjective. Not sure about flight time etc, but there are a few youtube clips on this sort of comparison against the STD props, 3 and 4 blade props. but it’s no where near as quiet as an M3P, but that is a different animal with a different purpose).

other than bumpers, and battery clips and gopro mounts are there any other software hacks / improvements that are available?

Again just a shooting the breeze question of wondering what is available?
