Hello peeps. I noticed this clicking sound today when i was switching the prop to the recommended 11x6 for tanks 3 & 4. I know this engine had a roller bearing at the rod so i don't know what is normal. Everything else feels very smooth with the exception of the sound. Video exagerates the volume of the sound a bit, it's less apparent in person.

Opinions?

Thanks!
