Hi!

I know there has been a lot of Bruder 574 conversions, but not one like this one..

The goal was to try to convert the Bruder 574 to RC with the very least amount of work during a weekend. (Easter had a long weekend and thus it would be possible)

Note that there is no steering servo in this conversion!





There are some 3D-printed parts in the front and in the back:



The front and rear axles are 30mm aluminum tubing with 2mm walls.


I re-used the wheels:



All the wheels are drive by a 12v 24rpm gear motor:




The hubs I got from Ebay didn't have a thread, so I tapped a M4 thread in them:




I 3D-printed a stencil to help guide where the holes should be:




Then I assembled the rear pivot:




















Cut away the fake axle to make room for wires going from the front to the back:




Assembled the front section:




Like in the rear there is a small screw holding hitting a small hole in the axle that fixes it in the printed part:






The motors are held in place by two M4 5mm long set screws, one on each side (for balancing the position in the tube):






I remove one screw from the firgelli actuators and re-insert that into the holder. That way the actuator is fixed inside the holder:
