Dv yeah I had (2)2s hard case lipos on their sides then (2)3s stacked. The lipo placement was a way around buying the flux trays. Not for sure on the diff fluid it's ether 500k or 10k. Feel likes 500k? For my the drive shafts I wanted to use some cheep hacked up screw driver shafts (chrome looking) but they were to hardened for my cheesy drill bits. I found some ornamental steel unhardened roses around the shop and hacked off the stems then I drilled the cross pins, cut up the same size drill bits as used for the hole for the pins. Slide the pins in, hit shaft with hammer to capture the pin, then ca glued them also.
