Been flying my CS X8 with a single 12,000 centered on the top for some time now, and I still have been getting "Bad IMU Status" indicators even with the new IMU V2 (WKM, 5.26). I am attributing this to being top heavy and since the IMU is located below the battery and above the PDB, plus normal vibrations throughout the frame. My plan is to go for dual batteries on booms 3 and 6 to free up the center frame for better avionics placement, but my question is what battery sizes to go for? I have been getting around 10-12 minutes with my 12k and a Zenmuse/GH4 payload, but i think two 12K's might be an overkill for that payload. We still will be flying heavier payloads such as RED/RoninM as well so I'll need to save some AUW for that as well (two 10ks?) What dual battery set up/payload/flight times is everyone running on their X8's? I am thinking dualies between 7000-10000mah. Also have to consider traveling with lipos: easier to have two small ones rather than one monster. Propulsion is: KDE 4014's, 17inch props, 60a ESC, Gryphon PDB.
