Hirobo Dauphine 60 Electric Conversion

Upper motor bearing support, battery boxes and electronics tray

Feb 1, 2026

I utilized the original engine upper bearing support. I had to slot the mounting holes to allow for pinion to main gear adjustment.

The battery boxes attach to the frame and utilize the existing motor mount. 2-M3 screws attach the box. The boxes are oversized a bit. The sleeves are used to secure the batteries and have a catch retainer. You might notice the holes in the sleeves are the depth of the M3 heads to ensure no rubbing on the batteries and will not pull out once the batteries are inserted.

The electronics tray holds the Axon, receiver and 900 backup receiver.

The ESC mounts to an existing tray Hirobo provided.
