Hi all,
I recently cracked the mount that holds the upper front arms. I’ve since replaced the mount with an aluminum HR model, but once I got her all back together and took it for a spin, I noticed this high pitch, grinding sound which gets louder with more throttle. I then thought it was the motor and pinion gears so I ordered and swapped for Arrma factory replacements.
Unfortunately, the sound is still extremely audible every time I take it for a spin. Without a video (currently away from home), can anyone recommend an issue I should check? Thanks in advance!
