(...) Hmm, I had dabbled with a similar solution, but inverted (with the motor driving the bottom gear and the two side gears the two outputs, but discarded it for reasons that escape me at the moment. I must investigate this further. Thanks! Owen. (15 years ago, 2-Feb-10, to lugnet.technic)

Here is yet another possible solution that I have found effective for something very similar (a vehicle that reverses its direction when it hits an obstacle). This one is purely mechanical (no electrical switch needed). (2 URLs) The mechanism relies (...) (15 years ago, 31-Jan-10, to lugnet.technic)

I've just posted a new update to (URL). This is an unusual update in that it does not add any new years of models (although I am working on 1995). Instead it makes a number of improvements to existing information. Reformatted some older pages to (...) (15 years ago, 28-Jan-10, to lugnet.technic, FTX) !

(...) A nice solution, but I doubt very much if my tray could push the pendulum upright (especially since the total angular travel would be the limited movement of the pendulum _plus_ the angle that the tri-blades had rotated). However, for (...) (15 years ago, 27-Jan-10, to lugnet.technic)
