Electrocuting the Atlantis
TDM:
Welcome to the madness.
XOAR PJN-E or PJM-E 12x6 works great.

Perhaps Cobra 3520-14 is a better option for the prop chosen and I assume it looks like it is a 60 size ship.
I would cut out everything out that used to hold the motor or fuel tank out, the engine crutch the fuel tank floor etc. Make sure you have airflow around the battery ESC and motor. A undersized spinner works great and looks pretty cool. With the larger motor I do not expect the system to run hot at all but cooling always helps.

I use an 11” prop for a similar airplane at 73 oz. The CA 11” prop is inefficient, hence it takes more battery, but the performance improvement is worth it.

If I just scale your figures by weight I get 3000mAh -- and that's what I would have bought across the board except that I chickened out and got a 3300mAh to try the first time, on the theory that an overweight plane in testing is better than a nice light pile of balsa trash after pooping out at the end of the pattern.

Yeah, 2700mah to 3000mah is all you need.

With the 3300mAh battery and the motor set into place (but no ESC, motor mount, etc.) it balances just about the same place that it does with the 46LA installed, dry.
So (A) the battery is going to get slid forward, and (B) I may just stick with the bigger battery for balance! (Because a tungsten motor mount would be silly, and I can't cut tungsten anyway).
