Technic General Discussion
Ngoc Nguyen replied to Jim's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Anyone has any idea why motors for propulsion in RC sets (like XL motor in 42070, 42030) aren't connected through clutch gears but those for normal functions are (like XL motor in 42055)? When an RC model hits the wall and the user unknowingly keeps the remote on, shouldn't the motors stall and possibly overheat, just as when the normal functions reach their ends but the switch is still on? -
Technic 2018 Set Discussion

Since we're talking about new molds, allow me to express my nostalgia about 2H 2016 sets which give us a supercar and a bunch of amazing new molds -

@Ctan Can you share some pictures that show the two gearboxes in the undercarriage? I'm particularly interested in the gear meshes that lead to the turntable. I, like Ctan, also work on visual materials. Maybe that's why I feel the impact of color vomit more sharply.

OMG them greens! My eyes.... There is a saying that goes red and green should in most cases, except Christmas, never be placed next to each other X_______x http://uxmovement.com/content/why-you-should-never-pair-green-and-red-on-the-web/ And Ackermann steering is there!!

Since there are no worm gears, I think the rubber bands will be employed in some mechanism to keep the telescopic boom from collapsing and keep the winch from dropping. There are 2 rubber bands, so it's likely. 42070 also uses portal axle hubs but has a 13L gear rack.

Opinions on LEGO Technic Theme
Ngoc Nguyen replied to Jim's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The only set with an off putting size for me is 42025. It has long measurements in two dimensions instead of one like other sets, so I ended up having nowhere to display it and disassembling it instead. Most other sets are big but are so in length only, so storing them isn't a problem for me. -
For one thing, the multidirectional gearbox in general requires more space than the multifunctional one. I'd much prefer the former because it is more intuitive to use.
