Farm Innovators Pro 4200 - Best way to run?

Ok, for those of you out there that have a farm innovators Pro 4200, what do you find is the best way to run this incubator? I am about to use it for the first time so would like to know its pros? cons? how have you had the most success with it?
TIA!

Completely ignore the built in temp and humidity gauge, cover it with paint or something, it's utterly useless and I mean that, they should be ashamed of themselves for even including it...

The built in temp gauge on mine was 7° off out of the box, and after I disassembled the thermometer unit and re-calibrated it was off a few degrees again within a weeks time, in short useless junk...

Get several decent thermometers to put inside the incubator instead, even the glass/cardboard one they include is not the best, mine was off by about 2° had to rip it off the backing and re-glue it in the proper place, eventually just discarded it for better and more reliable ones...

Once you get a few decent thermometers fire the thing up and watch the temps for about a week, I found that my unit had a tendency to creep up about 1-2° per week, thus requiring an adjustment down once a week or else it would approach dangerous heat levels... Adjusting with eggs in the unit is not for the faint hearted or advised but I found it necessary... A little slip can cook the eggs so be very careful, and after any adjustment keep a very close eye on it for several hours to make sure you didn't go to far up or down, it doesn't take much adjustment to alter the temp...

Also move the eggs around the incubator every day, there are hot spots under the heating elements so eggs under the element should be moved to the center and center eggs out each day, or confine the eggs to the center if you don't run it packed...

Beyond that you can get good hatch rates out of it if you babysit it and pay attention...

One thing I did to mine since I was hatching peafowl eggs was to make a foam extender ring that added more height, and although I rarely use that incubator now I always used it with the extension ring as I found it more evenly heated with less hot spots under the heating element like I had experienced initially...

I'll dig it out of storage and take a picture of the extension ring I made using 1/2" pink foam board tomorrow...

I agree with what MeepBeep said! I have 3 of the 4200s and I can't trust the built in thermometer/humidity gauge at all! I just bought 2 different cheap ones that measure temp/humidity at Walmart and use them instead!

I did not rotate my eggs within the racks(they were on the automatic turner) and so far I have 90% hatch rate with fresh eggs and a 74% rate with shipped(Ebay) eggs! But it makes sense that there would be hot spots under the heating element.

All in all, I really like the 4200s and if I need another incubator, I will buy this model again!

I've used this incubator for two hatches now and it does alright. I'm on my third right now and noticed that the motor on the automatic egg turner is running hot. 125° according to my thermometer... Is that something to be concerned with or is that a normal operation temp for this little motor? I never touched the motor in previous hatches so I don't know if it was running that hot before or not.
