Oh they are fun !

You have to pull the blades out first and one or more will likely break at the point where the round ball at the end....enters the socket.  However, once your repair is completed you can glue the blades in permanently.

Then the nose cone is free to come off.  Then two or so recessed screws need to come out.  this will get you inside.

The motor is way undersized for this job.  You can try to loosen the gearing and lubricate and you may get lucky.

However, in my case I lost two of them within a month of each other.

They work well when they do......I believe that little motor just could not keep up.

Hopefully you will have better luck than I did.  Be curious to know how you make out.

Thank you for letting me know the trick to getting inside the nacelle.

I did check all the gears and lubricated everything, but I wasn't lucky, because the drive train isn't the issue. Even without a load, i.e., disengaged from the drive train, the motor will run for about 30 seconds, then stop. I think the problem is probably the motor, as you suspected, or less likely, perhaps the capacitor (the only electronics besides the rectifier). I think the next step will be to try powering the motor directly from a DC power supply and see what happens.
