I flew mine until the ESC cut out, several TnG's, didn't time it but est ~12min. Loops and rolls well, post maiden inspection revealed battery came loose and slid back in compartment, will add some velcro to hold in place front to back. The only other item was the tail, out of the box one of the vert stab bolts was too short, barely got a nut on it, it seems like it may have pulled loose, as now there are threads to spare, may need epoxied back in. I spend a lot of time tweaking the elev/rudder linkage rods to reduce binding as well. I love this plane.
