Today when i was going taking off, i heard a single metallic noise in one motor.
It only sound once, and tried to replicate it moving from side to side without results.
Landed, Took off and didn't made any sound.
About 2 hours later i was going to make the second flight and it made the sound again. Landed and took the drone home.
I've been moving the motors to replicate the sound and try to have it on video, but it sounded just once (moving the motors with my fingers) and haven't been able to make it sound again.
The sound is like something inside the motor clicks as the motor spins, but it only sounds once.
PS: There is nothing wrong on the flight, it moved and reacted propperly without lose of potence or anything. Didn't check for temp on the motors, my bad. The sound doesn't continue after that first time (per flight?)
Edit: Got it on video: at 00:04 sounds weakly and then at 00:07 sound like the other times (first time i notice/heard the weak sound).
