I decided to start repairing my 380 that I crashed a couple of weeks ago, while waiting for my 450 replacement servo to arrive. First up was to replace the bent blade grip arms and inspect the spindle shaft. Luckily the spindle shaft wasn't bent in the crash :). After installing the new blade grip arms, I reassembled the rotor head. Job done!
Next up I removed all the cyclic servos, as they all broke in the crash. It was a pain to get the servo case apart! Then when I did, it popped open so I didn't have a chance to take a photo of the gear positions! Luckily I found a photo online of a similar servo and was able to figure it out. I then took a photo of the new installed gear set as a future reference. It was a pain to line all the gears up on their shafts! Especially the center shaft as it went though 2 gears. I coated the gears with some white lithium grease and closed up the case. Job done!
It turns out that the output shaft which the servo horn attaches to snapped in half during the crash. Probably because this shaft has many steps and features on it. Once the servo was assembled I plugged it into the servo test port of my iCharger 4010 Duo. It worked! Whew! Onto the other 2 servos.
The repair of the other 2 servos went much smoother, as now I knew what to expect.
