I clamp the rope between the axle and the disc, in both cases. It doesn't matter that the wheels can turn, as long as the rope is tight.

I did not buy the set, but built the set with my own bricks. So I also had to rebuild the spool (left on photo). By adding 2 wheels now (right on photo), I have increased the diameter to reduce the number of windings. After recalibration it was better, but still not completely. I don't know how much extra thread I used. Winding up a piece of thread beforehand will not solve the problem. It will then roll up completely, but will not unroll completely. I made the thread twice 25 cm shorter, without recalibration. Now it rolls up and down completely. Only when the crane is in its highest position, the hook will no longer touch the ground.

My hook stops halfway! If you look at Liebherr's documentation and use the lower structure as a reference, the Lego upper structure is only 45 till 55% of the original. I have extended the booms to 85% and therefore also had to use longer ropes. The calibration in the app seemed to work fine with those longer booms&ropes. The app works well with the longer booms&ropes, except for the hook. During calibration, the app rolled up the longer rope completely. When I use the app now to pull the hook, the motor stops halfway. Even the joystick in de app will not move up anymore. Down still works. Then you can again pull the hook till halfway. Even in the REcalibration of the hook (separate option in the app), everything seems fine, but the problem remains. Has someone the same problem?

I ordered 4 extra Large Angular Motor on bricklink.com for 15€ each and 16 black 3x19 frames on Lego.com in july. Unfortunately, I saw only the 26 yellow 3x19 frames and not the 9 gray ones. So I build it with my own bricks and without: - 9 3x19 frames - the new yellow 5x15 and 7x15 frames - 7x16 girders - 7x11 weight bricks - al lot of smaller bricks Luckily, the good old Power Function AA Battery Box fits in the weight brick holder. I had problems with the calibration in the Control+ app. The engine pulled until the mast fell over. I had to start over and block the rope by hand before it went wrong, for each calibration . Control+ app works fine now. Next step: extend the boom and jib to reach the normal proportions and see if the control+ app still can handle it.

Last week, I build it using my bricks (from other boxes) and Sariel’s speed build. The only missing necessary part was 6317490 light grey Large Angular Motor (called "MOTOR, NO. 15" by Lego). So I bought 45602 light blue Large Angular Motor. I was able to control the 3 motors with the BuWizz app, but it was difficult to change gear. Today I tried the Control+ app. Yes!!! The Control+ app accepts the 45602 light blue Large Angular Motor! Everything works fine (except the uncontrolled wiggling during the calibration)

I build the 42099 "4x4 X-treme Off-Roader" using the Lego build instructions, but without the new bricks and power functions. The new XL motors were difficult to replace, because they are a part of the structure. I had to use the old L motor, because it has more connections than the old XL motor. I used 3 L motors, the 8878 battery and 1 SBrick. Front axle solution: Motor and new 1x3x3 connector solution: Rear axle solution:

I build the Liebherr R 9800, using the video and photos above. I didn't buy any additional bricks, so I had to find a solution for a lot of missing bricks. I works with 2 SBricks and 8 motors. It's not completely finished. After 3 month of building, I had no desire to continue.

About the turn table: When I see these 2 photos, it seems that they are using 2 double wheels at each side: So I tried to build the a similar upper part of the turn table: Full upper part of the turn table: My conclusion : No new big Lego thurn table, not the 42082 contruction, but a new combination of normal Lego thurn table and wheels.
