Progress Thread - 8750 Marion Dragline

[TylerDSAudi]

I have had these on order for a bit and was looking to use them for my build. They are a bigger brushed motor like a 550 with built down stepped gear boxes. I was thinking of using these and building drums onto the shafts or mounting a big gear and building a big drum with a gear on it to rotate it.

These were ordered when I wanted to build it RC and hook these up to a speed controller, but i do want to change plans with your guys help. But without the know how or parts I need to buy I will be lost.

You can still run the model with radio control but use shore power. You can use many different units to get AC to DC, like an old computer power supply or search ebay and there are a lot of choices. You could mount inside if you have room (there never is) or have the DC conversion on the shore side and run the line to the model. Wired works too just more cable.

see I was thinking of using a computer power supply cause that plugs into 110v and then you'll have to convert it to whatever voltage you need. I would like to mount the power supply and such in a box ( switch shack ) like a real drag and run a cable to the shovel! Maybe I convert a small backhoe to move cable around
