question w/ CG5 dual axis motors

I installed a dual axis motor drive a few months ago but the slew speeds seem incredibly slow. I have an LX50 and at an 8x slew speed it is at least 20x faster than the 8x slew speed on the CG5. Originally I thought it was due to the very cold weather but it is slow inside as well. I've added new batteries and it is still incredibly slow. The clock drive does not keep up. I purchased it new on ebay but maybe it's a lemon. What do you think can be done, if anything?

There is probably nothing wrong with it. You may be confusing drive speed with slew speed. When manufacturers reference "motor drive" speeds, they usually mean, for example, 8x sidereal rate. This is nowhere NEAR fast enough for effective slewing. Slew rates depend on the manufacturer too, and are usually, as far as I've seen, simply referenced to their slowest one. So the slowest slew rate (which will be much faster than an 8x sidereal "correction" rate) is 1x and the fastest, if it is eight times as fast as that, will be 8x slew rate. One manufacturer's 8x slew won't necessarily have anything to do with that of another, or even another mount/motor from the same manufacturer.

"Corrector" rates are meant for correcting tracking for photography, or for very fine adjustment of the image position visually, not for slewing across the sky. I think what you have is probably not intended for slewing, but for fine adjustments of tracking.
