Re: Tips for Tuning Your RCX

The (RCX400) scope is a magnificent, albeit complicated, beast. I'm glad you don't have to become familiar with it in the bitter cold up north we have.
Couple of quick reference things about your RCX:
1) If you use a 120v/12v power supply make sure it is at least 5amps. Idiot me used a 3amp and experienced motor stalls and power resets.
2) The RCX electrical connectors seems to really, really hate shipping. If you experience electrical board failures such as can't find north, GPS failure, Tripod tilt failure--stuff along those lines--before sending it back open up the sides and remove and clean with isopropyl alcohol all the connectors. Reinstall and make sure they are tightly inserted.
3) Balance is critical. Check up on how to measure balance in both the horizontal and vertical planes. Then don't forget to recheck after every change. I had perfect balance on mine at first then over several months of incremental changes I failed to recheck the vertical balance. Good way to wear out motors.
4) You'll almost certainly desire a focal reducer at some point. Before purchasing one read the RCX forums extensively. The RCX has a very flat field and requires a focal reducer without field correction (So a typical one marked for SCT use doesn't work well). I know, I found this out belatedly.
Good luck. I gave you the short list that I wish I had when I first got my 12" RCX.
Once you get your RCX scope up and running you'll find it performs like a Superhero!
