I also have the new 4094 Inventor set.
After disassembling the 90 degree gearbox, and comparing the grooves with the
new clicky joints of <http://guide.lugnet.com/set/8558> #8558-1 Cahdok and
Gahdok, here are some observations:
1. The grooves LOOK similar to part <http://www.peeron.com/inv/parts/41681>,
but are different. Both have 24 teeth, but the internal diameters are
different: the motor/gearboxes have an internal diameter of 0.410", while
part #41681 has an internal diameter of 0.375".
2. <http://www.peeron.com/inv/parts/x278> is designed to snap into part
<http://www.peeron.com/inv/parts/41681> in set 8558, as well as others.
Part x278 DOES NOT mesh with the teeth on the new motor/gearboxes (because
of the friction pin on the end of x278, this can only be verified after
disassembling the gearbox, as I did)
3. The clicky hinges of set 8558 DO NOT mesh with the new motor/gearbox teeth.
Part x278 is simply too small (diameter) to mesh with the gearbox teeth.
The only logical conclusion is that there are new LEGO pieces coming in the
future that will utilize these new teeth.
4. Part <http://www.peeron.com/inv/parts/41679> is different still, with an
external diameter of approx 0.315". Again it has 24 teeth. Two of these
parts snap together around the big ring of part x278.
5. The Star Wars AT-TE <http://guide.lugnet.com/set/4482> and new AT-AT
<http://guide.lugnet.com/set/4483> also use similar clickly hinges in the
leg joints. Could these parts mesh with the new motor/gearboxes???
I don't know, (I don't have either set) but I was under the impression that
these clicky joints had the same geometry as those found in 8558.
6. BTW, the new clear motor spins at approx. 480 RPM (no load), versus
approx. 350 RPM (no load) for the standard mindstorms grey motors.
Measured with the LEGO speed computer. But as always, expect variability
between identical motors.
Build well!
John
