Unless you do extreme things it should be fine. All the gears insides the Train motors, Power Function motors and the NXT motors are made of Nylon while the pinion attached to the motor is made of metal. Image Source Since Nylon is much stronger than ABS plastic (normal LEGO plastic), the ABS would twist, tear or brake before damaging the nylon gears. ...

The LEGO customer service does provide replacements for defective parts, but only for parts which are still in production. Sometimes you'll need to send the broken part back to them. They don't repair the parts as such, just replace them. As for the micromotor, you're out of luck as it's not produced anymore. They might provide another motor as a ...

In short, yes it's perfectly safe to run your old 9v motors from your Power Functions battery box. This excellent online reference has a lot of information on various LEGO motors. Both the old 9v train motor and the Power Functions train motor are listed. The information on the site shows that the characteristics of the two motors are very similar with the ...

Here is another video from Sariel which shows that it returns to center: http://www.youtube.com/watch?v=T_Gvuzsngg8 With the 58122c01 Remote Control Unit it returns to center if the remote is not actuated. With the 64227 IR Speed Remote Control Unit it returns to central position when the stop button is pressed.

Well the power cable is the main difference, as one motor was made for the short-lived 9V RC system while the other is the current PF one. However, that doesn't mean the internals are the same. From Philo 's motor comparison page, you'll see that the PF motor is better, and that fortunately the performances are much improved [over the RC one], with an ...

Turns out the problem is that Servo motors need at least THREE wires. Two for the PWM and one for full power. I made a new connector (and I can attach a picture if anyone is interested . . . just don't have one handy right now) that had all four of the wires from the Lego brick connected to breadboarding pins and then I wired the two new wires to +9 and ...

The easiest solution, provided that motor is still in production, is to contact the LEGO customer service (this online form is usually the easiest way, but you can also call them), they'll usually provide a replacement without problem.

According to Philo's detailed analysis of the servomotor, it takes its commands from the C lines but needs to be powered as well: Being a Power Functions range member, it is fully integrated with this system, and receives its commended position through C1/C2 lines, and its power from supply lines. On a normal motor, C1/C2 duty cycle directly control ...

You need these old school 5292 puppies ;-) 2 of them. Check a motor comparison here You're gonna have to do some after-market mods but those are very powerful , I have them from the 8366 set. But as you can see in the review, there are pro's and con's on every engine. I suggest reading it in full, it's an amazing source of information and you'll learn a ...
