Time to finish installing the power train. Completed:
- Glued in the styrene stiffeners in the front of the lower hull
- Installed drive shaft bearings (height was adjusted slightly as a result of switching to the Mato gearboxes)
- Gearbox attachment points were reinforced using aluminum tubing (1/4" ID, 9/32" OD, .014" wall thickness)...their lengths extend an extra 1.5-mm (total of about 5.75-mm long) to replace the washers that were used as spacers to raise the gearboxes.
- Gearbox mounting plate is secured with #4 (#0 drive) self-tapping, square pan head screws. They’re ½" screws that have been cut down to about 7 mm. (possible source:

I’ve put some lithium grease and 3-in-1 oil into the gearboxes following thecommander’s guide (
