I thought that I recalled reading somewhere on the internet a long time ago that Power Functions motors have no internal gearing. What the? Well, it looks like that wasn't true. Now that I think of it, I think that I have heard the noise of the internal planetary gears when I run my Emerald Night. I'm just used to the sound, and I may have mistaken it for the buzz of the electric motor. But I question if it's really a good idea to include internal gearing. Couldn't they have a smaller assembly if there was no internal gearing? Or they could have a larger electric motor inside with more total power-output. I would also expect the motor to be cheaper because of the simpler preassembly. Yes, I am aware of the basic fact that the gears are used to trade speed for strength. Wouldn't it be better if they just let us build that with our Technic gear pieces? Because Technic gears would take more space, maybe a separate preassembled planetary gearbox? I think that there are more Technic models that use gears to increase the speed of the motor than decrease it. It would probably be better if they at-least reduced it to one lair of planetary gears. I only know the basics of how an electric motor works. But I don't know exactly what determines all the specifications. Is there a way to adjust the balance of speed and strength while the motor is being built? I would expect there to be some way.
