My Gen 1 Foil Drive is on the Cedrus project integrated mast and I desync’d the ESC when the plugs became partially unplugged intermittently. It burned out my FD original ESC and I replaced the battery box and ESC with a Maytech 160 amp ESC and had to change remote and receiver to get voltage telemetry. It ran okay for a few weeks then suddenly started lost power and was growling every time I put in more than 23% power. AI said it was likely the bearings and I checked them and the bearings were a bit gritty and a tiny bit loose,
To get the rear bearing out I literally pried the nose off, pulling the metal threaded inserts out of the nose. I pushed the wires up the mast to all the rear half of the motor mount system to be removed but i can see two screws coming from the front through the stator base plate but the heads are not visible, apparently behind the sealed front surface of the mount. I plan to grind a hole through the glued in surface but don’t understand how this thing was made with the heads of the screws going forward and backward both being concealed,
