I just got my 4094 Inventor set (i.e. the motorized string traversing
monkey) and just wanted to make a quick observation that I don't
think has been mentioned here before:
The 24 tooth gear in the worm gear box has an over-torque
relief mechanism in it (can't think of the proper term for this at the
moment... and I 'm not sure that "limited slip" is quite correct). If you
look closely, you can see that the gear is made out of two parts -
an outer rim with the 24 teeth and an inner hub with the crossaxle
socket. The hub appears to have 24 bumps on it. The outer ring
contacts these bumps at eight places. The mechanism is fairly stiff
and shouldn't give unless an undue force is being exerted. You can
test it for yourself by cranking on it with a liftarm and axle - you will
hear a loud click when it gives.
Also, I think it is pretty cool that the new motor is a cube - 4 studs
to a side (well, not counting the top studs, of course).

| (...) This partially balances the fact that this worm gear box is something more space-wasting than other assemblies, as well as the 90°degrees (I really don't know how to call it) gearbox that is supplied with this set. In fact I still find more (...) (21 years ago, 22-Aug-03, to lugnet.technic)
