It was Sariel's video featuring Efferman parts...

So in the end is it like Efferman's diff?

The boat is awesome, when I look at the sails I see wings for an ultralight powered by rubber bands.

Looking at the picture the gear looks.. painted?

Some diffs are a PITA mostly because sometimes under stress the small bevel gear in the center likes to fall and there is little you can do about it. A preassembled one solves the problem allowing to focus on what to do with the diff instead of how to prevent it to fail.

Still given the number of parts and the price of comparable sets without PU or PF, that puts de PU parts at 80€ and that isn't cost effective at all. PU is overpriced in all its forms.

I trust the designer didn't put the gears in such a way just to cause unnecessary grievance, specially since children need to operate it, Hubris and sarcasm make a poor combination.

My only concern is that raising the boom may take ages. I like they added something to lift, but no metal hook?

Look at the steering! I'm liking this a lot, no bricks wasted.

Oh, is kind of cute.

Three thoughts: I don't understand this set. Why Top Gear? Make up can help but can't make miracles. Neither do stickers. Watching the video.... they managed to make RC and Lego boring in one shot.

Sorry, where is it? I can't see it behind all those stickers.....

That is exactly what for years I wanted as an improvement to IR in PF. Wasn't that hard it looks... For the price I for sure will give it a try.

The industry is transitioning from mostly fakes to clones/competitors. So I guess there is more to talk about now than a few years ago. At least in technic... Perhaps some clone brand will realize that wheels usually are taller than wider and will get Lego in trouble.

Didn't know Clementoni, a pretty well known puzzle brand, had some compatible designs too.

There is no copyright for Lego parts, at best they might hold some design patents if they filled for them and got them granted but I that is not the case anymore for most of them, and anyways those expire after 20 years. As far as I know they hold 134 design patents under de company Lego A/S based in Denmark. For example: For the second one they still got 10 years, however most technic, be it studded or studless is free domain now. And a few of the patents are being contested. By the way patents are funny... just check this: (a design patent for a box)

I don't know if this belongs here... Regarding C+... I know there is some kind of non set specific soft to be released by TLG. and there are also some third party software options. Given any of those options Is it possible to implement some kind of electronic traction control? Since the motors have an indexer, given a 4WD car with 4 motors, one per wheel and accounting for small variations of wheel rotation due to turning... Would it be possible to detect wheel slippage and correct power delivery to that motor/wheel? Could something like that be implemented? Is C+ hub capable of powering 4 motors for real, would it need 2 hubs?

I sense Sticker Hell Incoming

Anything requiring weird angles in more than 2 dimensions can benefit from this. Thinking in architectural models like bridges.

That battery box is the intended counterpart to this motor. I am not sure but I don't think it is a brushless motor so the sparks probably are the brushes moving from one conmutator segment to the next. Maybe the brushes are worn down, or the springs have wakened. Dust, particles from the brushes, even humidity can cause that. The slowing and stopping sounds like a thermistor protecting the motor.

This ^ A sticky Index for all the reviews past and future.... Edit: I know there is an Index... but so outdated.....

I enjoy your reviews the most, I just check yours and If I see here a video review like Sariel's.ones I sometimes check those too. I deeply hate Facebook, despise Twitter, and fantasize with meteors reducing PInterest data centers to rumble, so yeah Eurobricks is my Lego info hub. Perhaps I am at outlier...just hope not. But I am old, my attention span goes beyond the 12 seconds, I am able to read, and don't get easily distracted by fast moving colors. Also my main monitors are 32" at work and 42.5" at home, and feel absolutely stupid consuming multimedia on a smartphone when I can use proper hardware... Of course not being a millenial helps paying for that hardware and having a healthy Lego budget. I really wonder how many mobile browsing, Facebook dwellers are paying for those Bugattis or Liebhers...

I meant in the last image, the power bar chart, I see the old PF-XL for example but not the Control+ XL

Isn't the chart missing the new motors?

Honestly I don't know, But I already had very bad experiences with some of the cables used in PF adapters and mindstorms, Like this The kind of plastic based on plants they are using is polyethylene I think. It is quite different from ABS, softer and more flexible, so not a feasible solution for everything. Polyethylene is quite stable, so no concerned by now... but just look at that picture... I don't know what changes can they make to the ABS but when I see cracks on new not stressed parts....
