Okay Fred, Maybe not anymore, but certainly it was in past years! See, I had both sets, and let me tell you, Lego weren't for static structures! Much of the Fischertechnik stuff is designed for devices using beam construction, like bridges and cranes and cement factories and things. But they also had a full set of gears and linkages way back, so nyah! Now, this is all from when my Dad gave me some sets in the late 70's, so I imagine they've made some improvements. Seriously though, Fischertechnik is designed in it's original form for a different purpose and a more advanced crowd, whereas Lego was originally for the younger crowd. Since then, F't. has retrofitted with simpler stuff, and Lego with more complicated stuff, probably to dig into each others' market shares. Both are pretty nice prototyping toys though, but I think Fischertechnik is more durable (except for one design flaw): it's a less brittle plastic, and it doesn't depend on tight fitting pieces to hold it together, but rather uses quarter-turn fasteners. i.e. when you drop a FT project, it isn't bound to shatter into it's primal bits! If you haven't played with these, give it a try--they're really useful! |> LEGO doesn't have a slip ring though. Weh'hell, that says it all, doesn't it?! -Olaf
