This weekend I went to "fly" OpenROV 241 in a pond and could not get it to go straight, it would only turn in circles. My left motor had a 'clank' noise and it was not the prop hitting the motor housing. You could turn the prop by hand and at a certain spot the shaft would shift to the side. I removed the motor and you could see the shaft shifting left and right as you turned it. Taking the motor apart, which is a challenge, the front bearing was shot. The rotor (magnets) were hitting on the stator. You could see a shiny spot on each part making the noise.
Has anyone replaced the bearings in the motors? And if so where did they buy them? Or are we just replacing the motors?
The way the motors are mounted and how the wires are hooked up this is not a fast fix.
I have probably 22 to 25 dives in only fresh water (pond, test tank, lake).
A 2nd motor shows the same problem and needs replacing.
