I was drawing something like 5 amps if i am to trust my meter.. After reducing the speed i consumed 1400MAH every 15 minutes on the same motor. But getting the speed up by another 15% tripled the draw.
Got my new torquemaster 45turn in today, haven't tested it yet since i have the thing apart but im hoping to do that tomorrow after i paint the undercarriage. Speaking of that
Some early stages of the cab. It is not supposed to look like anything real in particular. I was experimenting with front windshield angles and this one i liked best.
Here you can see the new scale of the machine. The new counterweight will allow me to add about 8lbs of ballast on top of what i already have (im still deciding how high i want to make it, hence as you see it is not really closed up yet). Side to side i've extended 1/4" each way; total of 1/2" (any bigger will look funny on the carriage after i add the walking ramps) Front is about 1/2" and about the same in the rear. So total about 1" of lenght added. Dimmensions are almost identical to a liebher 944 now.
The undercarriage... 2 3s lipos for the drive servos (~250oz torque @ 6v), a full size ESC with active brakes forward and reverse, a 6ch receiver, the turntable and the BEC all fit in there. Want to finish trimming it up and pulling out the switches and charge plugs tonight so i can paint it tomorrow. It goes down all sides, not just on top.
It cannot look any more scale and support the weight and have the unlimited rotation of the body.. I planned it more scale but decided function over form. It is a small model :\ I have the entire beam support system around the sprocket servos, vs gluing them to the side like everybody else does. It will carry a lot of weight which was the point. Stock bruder buckled so there went that idea.
Turntable and bearing are rated at something stupid like 200lbs distributed weight but with the hollow shaft call it 100lbs. Plenty! I do have a solid shaft too but what's the point. This one ain't bending
