I inserted a small acetate plate between the new battery compartment and the front of the board to avoid touching the Elev/Rudd servos. The ESC is mounted above the aileron servo and this layout has given me a C of G in the same place as when it was 1s. It weighs 57.5g (with battery) as opposed to the 1s 46.8g. I have no idea about any of the black art of amp draw etc but it's same set up in my PZ Sukhoi SU26m with the exception of the propeller (5x4.3) The only other modifications are a pilot, radio mast, smoothing the wing fillets, weathering and the G-NF markings of 249 Gold coast Squadron as a tribute to my Great Uncle.
It may not be to everyones taste, 2s, but after flying it as a 1s and as great as it was I am sure it will be much much more just like my Sukhoi was.
You can get the information on how to change the second aileron port into an esc port from Spektrum website (manuals) use the AR6400 manual.
If the board messes about and wont re bind then reset everything on the TX (Dx6i) and try again, this worked for me.
Now Parkzone/E Flite I need a 2s brushless FW190d or BF109 so my Spit can show them how it's done!
Here ya go, so you don't have to flip back 50 pages.

Would that brush less work with a 1s lipo? Just wanting to keep the weight low...

Most 1S Brushless setups won't make as much Power as the stock 8.4mm Brushed motor (because its geared), and those that do will be total amp hogs cutting flight times in 1/2.

More volts (2S) means less amps for the same power, increasing power and extending flight times.

Thank you rcmaniac, you can get a 1 cell AP03 amongst others but as UNGN says it really isn't worth it. My Spitfire isn't massively affected by the extra 10g and can still be flown at a slow jogging pace into a light headwind (3-6mph) with the AS3X working overtime and it's very stable at these low speeds.

That gearbox is interesting, looking to see how powerful the geared setup is coupled with the weight compared to the 2S setup.

Big Brown Truck is coming Monday with my first AS3X!!!

So newbie question (I've kept up with this thread from the start but will go back and reread eventually): Do I do any trimming on the TX or will AS3X take care of it all? I assume, I'll do sub-trim to get all of the control surfaces flush as my set up, make sure the control surfaces are moving and auto correcting in the proper direction. Then just fly?

There are U bends in the control rods that you use to center the control surfaces. After you take her up you made need to make few minor adjustments to the RODS. You really don't want to trim using the TX on AS3X as it takes it as a control input.

From what I've read, sub-trim is a no-no with AS3X. Mechanically trim the plane with the control rods.

That's right. Forgot about the u-bends...my first experience with that too. Good thing I asked.

Has anyone tried a mCPX lipo in this plane?
I used a 300mah 45/90c for some static tests, and this motor with the 4 blade reved up much higher !
