I had a crash which snapped the right front arm. I've made successful repairs to the drone in the past. So i thought I'd order the part, study some videos and attempt the repair myself. The drone is out of warranty. Everything about the repair went well, I followed what I felt were good instructions. I grounded myself and the drone and soldered carefully. upon finishing the repair the drone would no longer power up whereas it did prior. Any thoughts would be greatly appreciated.
