When you are ready, let's talk about the parts layout in the tiny battery compartment.

Here is mine with a 4S2200 pack - very tight. 55 Amp ESC on the left, receiver on the right. You need to get the antennas away from the battery to avoid loss of signal, preferably outside the compartment and on the wing. I had to cut bigger air vent hole over the ESC and add a scoop to force air by it and enlarge the outlet hole. As I build the next one, I may move the RX out of the battery compartment and embed it in the wing.
Others in our club have stuck the ESC through the hatch with the heatsink sticking out.1 Photo

No picture necessary of my innards. Everything is just crammed into that tiny compartment under the canopy.
Got the same 4s EDF as you on order, but delivery is running really slow. I'm thinking I will mount my 60 amp ESC outside on top, just in front of the EDF when I install everything. That will help it cool and will make more room inside the fuse.
I'm thinking also thinking about addressing what you said about the battery interfering with signal to the receiver. I'm using an AR620 which has never given me signal troubles in the past and it's too bulky to mount outside. So not sure what I'll do there.

The 4s setup made a huge difference in the way my Neptune flies. Only a little faster, but much more thrust and power. As Louie said, the plane will take directly off of our grass field without having to toss it. Guys at the field were talking about how cool the ground take-off looked, mine will get off the ground in about 15 feet. It will taxi a little too.
Mounting the bigger ESC on top of the plane, in front of the EDF, worked out well too. The ESC ran perfectly cool up there and it made a lot more room under the canopy for the bigger 4s battery. The ESC doesn't look as bad as I expected sitting on top of the plane like that either.

Here is my version. I smoked one 55 Amp ESC because I couldn't get the heat out of the battery compartment. On this one I cut a recess in front of the fan as deep as possible without getting into the finger holes, with the flat heatsink on top and pockets for the bumps on the circuit board. I had a 60 Amp Eflite ESC so I lengthened the battery leads on the ESC and shortened the motor leads to the nub. I drilled in the power leads on both sides of the hatch magnet and slit the servo lead in the foam from the top.
I bedded the ESC in a bunch of 5 minute epoxy.
Now I have good airflow over the ESC heatsink, room for the 4S battery and AR410 RX without crowding.

I can't see the need for a stabilizing receiver, this wing flies smoothly and is not twitchy.
