February 9, 20214 yr Hi @efferman, Long time lurker here - finally registered to ask my burning questions . Love the rotator! Could wee see more of your rear axle setup? The render you posted above doesn't include any linkages/control arms. I am very curious to see the geometry because I do not see the use of a extendable driveshaft. That brings me to my second question; with the model so heavy, how are you able to utilize stock u-joints? I do not see any gearing on the axle, which makes me believe the torque transmitted through the driveshaft must be high. Both of these are areas where I encountered difficulties when building my LPE-powered truck. Thank you in advance!

The beams in front are pushing the frame while driving forward. The Suspension travel is only an half stud, so a extendable driveshaft isnt neccessary. The whole reduction is at the diff. Additional up and downgearing adding a lot of resistance, so it is better with the single reduction. With the allwheeldrive the U-joints should survive, if not, there are metal u-joints on the market. Edited February 10, 20214 yr by efferman

Looking forward to seeing more. Those 3D printed axle housings also look quite handy :)

February 14, 20214 yr Author First Prototype of the Trailer, The Kingpin has to move 1 or two studs forward, but everything else seems ok. 9x6 plates would be cool
February 22, 20214 yr Author This time i have spend more than 2 minutes to the video. Hopefully it was worth.
February 23, 20214 yr Very nice video. It told me everything I needed to know about this moc...thanks! It will be a terrific build.
February 23, 20214 yr Author Thank you very much, but there are two functions not shown. The difflock, and the freerun on the winches.
February 25, 20214 yr Author got a small pre production motor and integrated it into the 42122. The Servo and the Battbox are a little bit Visible.
February 25, 20214 yr Oooh, that looks very interesting. 5x3x2 studs right? Loving the connectivity options, much better than m-motor in that sense.

But there are no pin holes in the direction of the drive axis, right? That is useful even on the PF M motor because you can just put it on an axle and "secure" it with at least one pin in the same direction, But the motor shown should be more easily integrable in vehicles. Do you plan to sell these in the future?

The Serial Motor has two pinholes on the output side which i have mentioned to the manufacturer.

I see, with half stud offset, of course than its possible.Thanks for the link, the stats look promising - I imagine many small cars with multiple of these driving one axle or more. I'd love to have a servo motor in that size and form factor.

February 25, 20214 yr 9 minutes ago, efferman said: me too, but when this would be pf compatible...... Yeah, "Has a working voltage of 3.3 to 6 V" - what a pity. This is more oriented to something like Arduino or MicroBit, even the bigger one which would fit to the TECHNIC theme better.

March 2, 20213 yr I just love this cab design of the TGS so much... also makes me sad that there is currently no truck in the Technic lineup in the scale of 42043... Are you intending to add suspension on the rear axle?
