I installed the new servo arm into the spring system and tested it, but in one of the trials, the crook where the servo arm is placed into the bulkhead broke off, so I had to redesign the bulkhead so that the fillet value on the corner where the bulkhead crook broke off to a greater value. The increased value on the fillet will hopefully increase the crook’s resistance to snapping. Also I had to solder together a female XT-30 connector port to another wire that plugged into the Li-ion charger because I didn’t have the adapter. The old wire was a female XT-60 connector which didn’t work with my male XT-30 connector. I also epoxied the bungee cord connected to the nose cone to the upper body tube.
