strong textHello, “hi flyer” here. Name is Ed. I’m 73 and into R/C years in /out. Last good number. Helies and multi quads. Had same problem as U. I’ve found a number of reasons this happens. Loose power connections or ‘cold solder’ joint! Power wire comes loose for spilt second is all it takes. Most common, ESC
failure, due to heat or long time use and they go out or some burn. Had that happen too. Some motors will break down from heat or long ware. I’m had some 100 plus flights on some motors but I grease the bearings of all motors when I purchase them. Saves major crashes and repairs. Hope this helps. Good Flying.
I have a number of S550 quads and some home brew and my latest projects are APM with FPV/OSD set up with a 13.5 inch TV 12 volt screen from Wal Mart. How Sweet on the Eyes that is! hi hi
