Thank you for the information. I did skim through the thread, will go back and read it through.

Hello all. I am debating whether I should purchase the LEGO Liebherr R 9800 Excavator. It looks like a really great set, but my concern is, since it is controlled via the Control + app, does this mean that say ten years down the line it might just be a big paperweight? Like what happens if LEGO stops supporting the app?

So I've read that LEGO and Pitsco developed the Tetrix robotics system together, and that the Tetrix system is 100% compatible with LEGO Mindstorms. I was wondering that since Mindstorms uses Technic pieces, could one then use Tetrix gears in LEGO Technic builds where the gear train might be too strained using standard LEGO gears? Has anyone done this? Thanks.

Thanks for the welcomes

I had clicked the "Quote" button, but it won't quote anything. The post I was responding to however was from eurotrash (post #5): Just bumping this thread as I found it interesting, but with regards to someone "going back to Meccano," well the modern Meccano from the official Meccano company I can agree with this on, but with regards to the reproduction and custom Meccano one can buy from third-party sellers, one can build some incredibly complex stuff with. Basically miniature engineering. There are tons of parts available, including custom parts. Personally I like both LEGO Technic and Meccano regarding engineering-oriented constructions.

My name is Kyle. I have recently been getting into building construction toys/systems and also robotics and such. Everything from LEGO Mindstorms, LEGO Technic, and LEGO trains to other robotics systems and systems such as Meccano (reproduction Meccano from third-party manufacturers and sellers though, not the Meccano made by the Meccano company right now), to electronics, etc...I bought my first LEGO Technic system just recently, the 4x4 rock crawler.
