Hello guys! Crashed my maviczoom couple days ago,props got broken ,and that shiny ,mirror looking piece on the back dropped but somehow retrieved it...i was actually expecting a lot more damage,after glueing it back,replacing props managed to get it back up but it sounds like the back sensors  are
malfunctioning coz that radar chart obstacle avoidance beeping sound won't stop,drone can't go backwards either unless I disable all obstacle avoidance and that's dangerous..I hv noticed one of the two upward back infrared red sensors isn't coming on...Are they both suposed to be on ,..theres also that error saing BRAKING,BRING STICKS TO CENTER,something like that...what needs to be replaced,i can probably do it with your videos assistance..Thanks

Not interested in warranty issues....just tell me how to fix it based on the details I've given you,whether it's esc board,back sensors etc that needs replacing..I expect steps from you on how to troubleshoot not this bs you giving me! How does putting back props or that shiny piece warrant disassembly?
