Currently left/right movement direction change triggered by blocking movement and it is essential for makeing paddle defelecting ball. And friction on sliding 8t gear is caused by.... uh... It is very hard to explain. As a possible explanation, the problem arises from the fact that the 8t gear need to sliding on axle axis while transfer power to up/down movement. It is almost like trying to put a beam in the center square hole of a 28t turntable and move the turntable at the same time while beam is rotate. As the clearance disappears, severe friction occurs in that area. Of course I seen this before making my model but this used mindstorm and I want pure mechanical. Because using mindstorm on this kind of machine is to easy to make.

How about put extra PF batterybox and use PF switch with geekservo?

Version 1 is failed. Seems like has to much friction on sliding 8t gear on up/down movement. I tried to fix it for almost 15 days ~ 1 month but nothing improved. I need to scrap this and remake.

I never heard that part can assemble with joint ball. And even if it can, that part didn't sold separately so meanless.

For me it looks like F1 set's front tire. Bruno conformed that tire can fit on 1:8 wheel on few pages ago

Next cada 1:8 is mercedes AMG GT3.

Few days ago I finally finish to build B model of 8479. The raider transporter vehicle. Of course like my previous 8480 studless A and B model, this is also made part from A model. Because of that, few part looks different with original model. Main reason is I used lot less angle connector in studless A model than original version. All function in original B model is still work same on studless version except motorized drive. I will make video and instruction soon and make C Dune buggy and D Walker model too.

Because CADA is china company and one of the kick sauber driver(also alfa romeo which they made before) is chinise driver Zhōu guànyǔ.

It must be a radio certification issue. At least in Korea where I live, any device that uses radio waves must be certified for sale. However, infrared and Bluetooth do not fall under this category, which is why PF and PU used infrared and Bluetooth, respectively.

Than super rare part 56908 wheel on yellow will come too. (4 in 1 set currently)

This will work. Or if you don't want connect with turntable, this will work.

There is some overlap in the concept since a medium-sized wheel loader model is planned, but a mining loader flagship would be fine too. And if this year's flagship is construction vehicle, I want see tower crane. If it is not construction releated, I want see this kind of firetruck.

Are you know this forklift's model name? It looks perfect to use this.

1. Don't have any offical motoried switch. Normal switch even look like need lot of torque but you can find some example of motorised switch on internet. 2. Current version of pneumatic is work only with overpressure way. You can create vacum using switch with cylinder like video under here but if you don't want it you need this part from very old set.

Every lego set can fly If you throw strong enough

Is the new black battery box can proportional control servo?

When those 6L screw was relesed, I instantly thought it will very good for some kind of XY machine. And as I thought about that, the Pong game naturally came to my mind. After some research, there is some of lego pong machine on youtube but at least I can find is only one is pure mechanical and it has very small screen. So I decided to try making a larger version using those screw, but the first version I made almost half a year ago was a complete flop and I forgot about the theme for a while after that. But then I realized that this one fits the theme of this contest perfectly. This is working prototype of game board. In order to implement this game, a mechanism that changes the direction of rotation when something blocks it during rotation was essential. All the mechanism I tried to make my self or found on YouTube failed until I finally succeeded by using the method in the video below. Very thanks to @TechnicBrickPower. All other mechanism is failed to working. I little modifited it using newer parts. And at first I used screws for the up and down movement too, but since that didn't work out well, I ended up using a chain with a link with a stick from Pac-Man arcade machine. The chain skips a little bit when the paddle touches the ball(red 1L beam on video), but overall I don't think it'll be a big problem. Currently game speed seems little slow but it will solvable using 2 L motor with up gearing. Currently use 1 L motor without any gearing except for slowdown up-down movement. Now I need to make paddle, score counter and arcade machine itself.

I tried use this part as balance spring before but failed. That hose idea looks good.

Thank you for making it clear.

Suddenly rule become complecated. Considering new rule, this is not allowed. Right?

As far as I know this is only part which has plate thick pin.

Vespa wheel with 7 GBC balls can work as bearing.

Thanks.

Oh and sorry, but I have one more question that's on my mind. I think there was a similar discussion above, but I didn't understand the conclusion. I've decided what I'm going to make, so this is a curious question that has nothing to do with my current build. Are these kind of characters allowed? Technically those are not vehicle but also can't count as animal or some living things. Game Metal slug - Jupiter king Rick and Morty - Butter robot
