 | | Minnesota AFOL makes it on Owatonna Today show
|

Well, it is not much of a media watch, because it is such a small market, but I'm going to be on the local cable access television "The Owatonna Today Show" (indian name pronounced oh-wah-tah-na). On October 26th, I'll be on for a whopping 12 (...) (19 years ago, 25-Oct-05, to lugnet.mediawatch, lugnet.technic)

(...) Hello, If you have not already seen it you should check out this website: (URL) There are a couple of really nice cranes, as well as downloadable spreadsheets with info on truss design. Hope that helps! Ben (19 years ago, 25-Oct-05, to lugnet.technic, FTX)

I've been toying around with the idea of building a medium scale lattice boom crawler crane, and was looking for some resources on building a good strong boom structure. I figure I want a 10x10 square frame main boom, and slightly smaller scaled jib (...) (19 years ago, 23-Oct-05, to lugnet.technic)

(...) Anyway, I'm glad I'm not the only one to have tackled this problem. As soon as I bought an 8856 helicopter (URL) I thought "That's not how a real helicopter works" and began thinking how to do it properly. This was the main reason I sent TLG (...) (19 years ago, 23-Oct-05, to lugnet.technic)

Here's my MOC of an Apache helicopter, built to 1:20 scale, compatible with Technic figures.

(...) I suspect it's bad design. Perhaps the way the brushes rub on the PCB as pointed out by Philo ((URL) "This higher friction explains why 43362 stops faster when you give the shaft a twirl, and why its no-load current is higher (9mA vs. 3.5mA)".
