Ok, I've recently owned a CPC 11" and I am VERY excited to be upgrading to a 14" RCX. I went back and ready literally hundreds of posts from this forum on the rcx and I was really scared of the things I read. I ended up sending the scope strait from the dealer to Dr. Clay just to be safe. From you rcx owners out there, what should I expect? Is there anything I can do to keep away from these pesky problems that seem to be present in a large fraction of these scopes?
Thanks!

Electrical problems seem to plague the RCX.
There does not seem to be enough protection built into the circuitry.
I would strongly suggest you get a right-angle pigtail plug (Scopstuff offers one) to avoid fork induced bending of the power plug as the forks slew.
I would also suggest operating the scope solely from a battery pack such as a used to jump start a car. Avoid using a 120v/12v power supply as they seem to fry the main board with some regularity.
I run mine off a deep cycle marine battery.
Other problems seen with some regularity appear to be failures of the Dec motor. Since it is usually the dec motor I would venture a guess and opinion that weight imbalance may be a root cause.
Lastly, shipping seems to cause loosening of plugs interconnecting circuit boards within the scope. This is probably the single biggest cause of scopes dead-on-arrival.
If you don't mind poking around inside your scopes innards, you can remove the bottom plate and fork panels and (after grounding oneself) carefully make sure each and every plug is seated. All told there are somewhere around 25 plugs.

you should expect a scope that performs quite well.
refurbished means brought back to factory good as new specs,
maybe some minor cosmetic blem, but nothing mechanical or optical. dr clay should make it even better, he has some tweaks and adjustments he does, and add a custom object base on older scopes.
basically you should get a scope I would drool all over..

Maybe I got lucky (bought mine used and the original owner took some great pics) but I have never ever had a problem with mine. Do I represent the silent majority I don't know.
For me the $620 for two years sky assurance (when you buy a "3 year plan" it only extends the warranty 2 years not three!) which I was able to get the original owner to buy and then transfer to my name has been an investment that I didn't get to use, I guess luckily, but I still might send it in for a free cleaning/checkup before it expires.
Expect a scope with the best views you have ever seen through a personally owned scope.
Expect to read the manual a few times and ask us for help when it doesn't quite slew perfectly to the alignment stars (it happens, I deal with it).
Expect to take some precautions which were well-said above, and expect some worry each time you turn it on or run the focus motors.
Expect to forget all the potential drawback the first time you look through a wide angle eyepiece or see how crisp jupiter is at 600x if your seeing supports it. Even at 300x you will be happy with the view.
Keep in mind that most people only join a particular forum if they have problems or feel the need to vent frustrations. You usually don't hear about the good ones which is why I try to be a vocal proponent for meade's RCX400.

Good to hear. What is the best defense for the run away focus issue? Should I just get a crayford focuser and not use the electric focuser if at all possible?

You use the focus motors for collimation. Mine keeps it pretty well though, so yes a crayford focuser will minimize "wear and tear" on the focus motors.

Ive had my 14" RCX-400 for 3 years now. Still kicking, and no major issues.
I use focus every time i use the scope.
Only real bummer is that the focus readout always defaults to -0.51 on the display regardless of what it was on before i parked the scope. So i Sync it every time i power on to overcome this.
I think this is a backup battery that is on the main board, but havent bothered to look at it, as its going really good.

I have heard a good technique to keep the focus motor in tip-top shape is to run it to its stops every so often.
These actions redistribute the grease so you don't develop any bind points the motors must struggle with.
A couple people have reported the screw falling off inside. That fix can be done but it sounds like a beast to do.
In addition, there is a flat battery on the back of the control board. It is gotten to by removing the bottom plate and then playing a skilled game of "operation" to get it out and replaced.
Good time to make sure all the wire connectors to the main board are firmly seated--there are ten of them on this 1.5"x6" board.
In regards to collimation, you should probably collimate with your imaging setup. (ie use the camera).
If you collimate with an Eyepiece then switch to camera you may find your collimation has changed. At least it does with mine. I note that I actually have slightly off collimation on my diagonal so I have three states of collimation: camera, straight through & w/diagonal. I make the camera perfect and bear the other two (slightly off) conditions.
The factory default collimation on mine was pretty good until I accidentally overrode the factory default by hitting the wrong key combination...but that's another story.

Well it seems my predisposed worries were warranted. Dr. Clay received my scope today and it is as dead as can be. The one good thing is that it is in the hands of professionals right now. OPT sounded like they were on top of it though. SIGH!!!!!! I was looking forward to getting my hands on it but it looks like it might be awhile now.

Dr. Clay probably knows more about fixing the scopes than the boys in the back room at Meade.

From what I have heard you are absolutely correct. I am actually very lucky that he has the scope right now and not me. He's already assured me that they will take care of it. Great guy!

He doesn't 'fix' these scopes. He only adjusts them and checks function.
Meade won't provide him with parts any more than they will provide us.
If your scope is dead, he will almost certainly return it directly to Meade at Irving for repair.
From my conversations with Meade, they repair all RCX scopes in Irving (others are sent on to Mexico).
The RCX scopes are usually repaired in a 'batch'. So your repair time will vary depending on when it arrives in the repair cycle for the next batch.
My first repair was 6 weeks from my door back to it. The second repair was 10 weeks door to door.

I'm in the minority but I was NOT expecting that!! Yes lucky you had it shipped to Dr Clay, I hope he can help!
Man are the working RCX400s on fork mounts countable on one hand or something??? I know the MaxMounts are since they only produced a "handful" of them. I guess I am not going to sell mine now, and if I did I would not ship! The connections must work themselves loose or the many interior wires break or something in the back of the truck. I am fairly sure it WAS in refurbed to 100% standards when it left the factory... one can only hope anyway....

My first repair came back with a complete checklist that covered every operation the scope was capable of.
I opened the box. Plugged it into power. The display came on for a few seconds then went blank.
After checking everything including opening the base and re-seating every plug I contacted Meade and was told to 'send it back again.".
They replaced the main control board.
It was already a new one. Might have been bad. <shrugs>
I was tempted to just sell it as soon as it came back this time but I didn't. Seems to be working and even the OTA temp sensor, which never worked, has come to life.
My friend has a 14" RCX. Mysteriously his main control board also went out and his scope is on the way back to Meade.
Now I only run it off a battery with a right-angle pigtail...

I have had no problems with the Meade supplied 5 AMP (special to the RCX!! Don't use less than that!) AC power supply, but usually I run mine with Powertank 17Ah battery and the scopestuff DC plug with built in right angle adapter.

Well, I got good news faster than I expected to hear ANY news. My dealer contacted Meade to figure out what to do and the outlook for getting Dr. Clay a spare mother board was not good due to the fact that Meade had none.
I got an e-mail this morning from Dr. Clay stating these facts but then he said it was purring like a kitten. He said he had a spare (new) MB laying around his work shop. He got it installed and everything is working perfectly (knock knock).
I thought about not sending the scope to Dr. Clay but then I guess common sense kicked in and now I am very lucky I did. He really does care about every piece of equipment he touches. Every scope I own from now on will go and spend some time with Dr. Clay!!
Whew!! crisis averted, who knows how long it would have taken Meade to get spare parts!!

Sounds like Dr. Clay & Co. can fix a scope after all...
Eh, Pess? 
As for me, after a very bad experience with Meade with respect to scope returns, I will do just about anything to avoid sending a scope back to them ever again. And I know how to use a soldering iron.

I will be driving to pick the scope up as to stay away from the horror stories I have heard regarding "freighting" these scopes. Is there anything I can do to keep away from the electrical problems as I am scared to even look at the thing now? Until I construct my observatory this scope will probably be set up and torn down every time I use it. Any advice? Is there any way to set this scope up (forget about putting it on a wedge, that would be impossible by myself) Alt-Az by myself? I've seen a few posts about special handles that help ergonomically, does anyone know what they're called?
Thanks!!

I don't know if Meade changed their policy since mid June but I was told by the head RCX service guy, (who shall remain nameless here) in no uncertain terms that EVERYONE, including Dr. Clay, could not get spare parts and all scopes had to be returned to Irving.

Peterson Engineering Get a Grip handles. The best accessory to get first is a friend to help set up. The RCX 12 weighs around 90 pounds and even alt az is not fun; getting a 14 up on the tripod yourself is not smart.

Good call. 120 lbs doesn't look so bad on paper but I'm sure it's a different story when it's starin' you in the face!
Well things are looking good at this point. Dr. Clay has finished the repairs and is now testing the scope and loading it's hard drive with all kinds of stuff. Looks like I'll have it in my hand sooner rather than later.

RCX service guy may not be as high as General/Executive Manager, so i think this may have come from top down. But might be a one off, time will tell.
Alex, first thing i would do is put a reverse Zenner diode across the DC line to the scope's power socket. Look for 15V to 16V and around 5W power rating.
This will prevent overvoltage by some unfortunate event, and also provide any high voltage discharges from other circuits that are inductive inside, like motors relays etc.

It appears that the parts Dr. Clay used to fix the subject scope were salvaged from another scope that was lying about, therefore Meade Irvine had nothing to do with supplying the parts, so your contact's pronouncement appears valid. Personally, I think it is a very bad policy and will dissuade many (including me) from ever getting one of their products again.

Why hasn't anyone figured out a way to separate the optics from the electronics on an alt-az scope, hence making a 'modular' telescope. That way you only need to send them the bad module. This will save both parties significant shipping costs given the heavy weight of these large scopes. At the minimum they should make the OTA detachable from the mount. What a waste of natural resources to ship these beasts back and forth.

He may just have opened it up and re-seated the plugs. There are ten plugs alone on the control board.
Since it left the factory in working order (Irving runs a really, really comprehensive final test) basically the only thing that could result in a DOA scope would be a plug loosening in transit.
That's what happened to mine when I first got it. In my case the GPS & Level North didn't function and it was due to a loose connection in the Fork Arm.
On a sad note Meade appears to have made the announcement that RCX style scope (Now called ACF400) will never re-start production with the exception of OTA only 16" & 20" tubes.
I think this is going to hit the RCX community very hard. Repairs for these problematic scopes are ridiculously expensive.
I hope somewhere down the line Meade releases schematics like they have with the Lx200 series so that third party folks have a shot at helping us keep them running.

Well I made the trip to Arkansas to pick my scope up from Dr. Clay. So far the scope seems pretty much new. Due to spotty weather I haven't gotten the chance to test the optics/GOTO. I received a GPS fix from inside of my house and all three of the focus/collimation motors seem to be working perfectly.
I really am lucky the scope went to ASO because I found out from OPT that Meade had no spare motherboards on hand so it could have been interesting trying to get my hands on one. I was told I could possibly expect to wait a year! Dr. Clay had an extra (new) MB on hand and now it works great. He checked every wire and tested every component, along with polishing the optics and loading my AS II with tours/catalogs, so for the time being I have one of the few functioning RCX's.
