I sure like the hinged electronics board idea, makes for easy inspection and service. The wires on the voltage side of the Talons run inside the C-Channel and might make it tough to hinge in our case.
I can reach in with my hands and change breakers. The wago connectors on the non-battery side are positioned so I can fit the screwdriver in and change a wire (the battery side is more difficult, but three bolts and the battery case is off the electronics board).
Metal shavings coming out of the gear boxes is now concerning me as well.
Mounting on top of the transmissions is out because the shooter will be above the transmissions and when down will not leave any room to mount anything up there. When the shooter is up, there is plenty of room to see through the motors. Might have to see if there is a way to raise the shooter to make room for the PDB.
Sure would be nice to have a smaller PDB
Thanks for all the input so far.
