Is it true that the LX200 series use plastic RA and DEC gears?

Hi:

No, absolutely not. Some of the gears in the gear trains are nylon/plastic, but
the final worm and wheel are not. You can get "Buck's Gears" to replace those
plastic components with metal, and some people have done this, but it has not
been demonstated to me that there's any benefit to this other than possible
peace of mind.

Peace,
