Hello all, (4 URLs) I have a 4032 set with IBERIA stickers to offer for trade. It is sold onboard only on IBERIA airlines for a limited period. I would like to trade it for two used 5120 technic-electric polarity inverters ((URL)). This special (...) (20 years ago, 5-Jun-04, to lugnet.market.buy-sell-trade, lugnet.town, lugnet.technic, FTX)

Hello, I have just got a LEGO 8386 Ferrari F1 Racer 1:10 set and have dicovered a new part, cant find other sets with it so it seems that i have been used in this set first. You can see the part here: (URL) of the car (without decals) is seen here, (...) (20 years ago, 5-Jun-04, to lugnet.technic)

(...) From what I've been told of mechanical physics, part distortion is also a concern. There's a tradeoff between making the pump design sturdier and keeping the overall weight/size down. Flat component pumps can be squeezed into available empty (...) (20 years ago, 5-Jun-04, to lugnet.technic, FTX)

You could place cylinders anywhere you've got a little open space, rather than having to make space for a bulky cluster of them. (URL) (...) (20 years ago, 3-Jun-04, to lugnet.technic, FTX)
