I was flying my spark and landed on a grass, grass wasn't that high but I got a warning saying motor obstructed? How do I check if motors are clean? Everything seems fly when I fly it again though.. I'm scared it might get worse if I don't clean the motors or something?

Thanks for your help

Everything seems fine *

The motor hit grass blades thats why u got message so im sure when u restarted drone it was ok

Please clean the drone and restart to check the performance first. If the error message does not pop up and everything works well, no worries, it perhaps hit grass or misinformation. Take care when you test.
