I have a couple of the cheap AR6200's I bought from oomodel.  They look IDENTICAL to the "real deal".  Even down to the stickers on the back of them and their SAT recievers.

I cant say with certainty that they are clones...but assume so because of the following...

1.  They dont have the updated firmware.  Meaning when you manually test a "brown out" condition...the LED doesnt flash...just links back up and stays solid amber/orange.
2.  WHY would Spektrum dump a large amount of these RX to a distributor/s to be sold to the public that have the older, unreliable firmware and at such a cost that they can undersell them by 1/3 to 1/2 the price and still make it a profitable venture (for the distributor/seller)?

I recently discussed this with a couple of club members that also bought some of these RX units from oomodel.  They never thought about my 2 above points and swayed to the side of agreeing with me on it.

I think that my stance on these are that they are just better copied clones.  Not so much as the internal electronics...but the casing that they come in, thus the little higher price.  Although I would love to be proved wrong here as I would buy even more of these if they are the "real deal".

I havent had a bit of trouble out of any of my "cheaper" Spektrum RX's though (orange or otherwise) but I always do have it in the back of my mind when I am flying a model that is outfitted with one of these.  So someone proving me wrong may remove that bit of doubt that is always there when flying these RX.

Just my .02's</p>
