I have been having some issues with my drone the last few days! As I am flying around thinking everything is going good, my drone drops out of the air. I have no idea what would be causing the issue. In the video you will see several times that I caught this on video. There were many other times this same exact thing happened that I was not able to catch on video. First set of Clips: I was running Cobra 2207 2400 kv Motors. One broke and I switched out all the motors to EMAX Special Ed's 2450 KV. Race Course Clips: Only difference in the quad was the motors I switchedto EMAX Part List: Frame: Armattan Rooster FC: DYS F4 PRO ESC: Spedix 30a ES30 HV Motors: Cobra/EMAX (see Upper) VTX:TBS unify pro hv QCAM: Foxeer Arrow V3 Receiver: FrSky XSR GOPro Hero 4 Session. (wifi was not on, as this was happening when the GOPRO was no on the quad as well) Taranis QX7 Below is the video that goes into a little bit of detail as to what is happening. If anyone knows what is causing this and how I can fix this issue, PLEASE, let me know. Thanks in advance!!!
