Default B44 ESC/RX layout advice please

I just finished building my B44 and am now figuring out how to layout the ESC and RX. From the instructions as well as the pics of the B44 on the AE website, it seems they suggest installing the ESC in front of the motor and the RX behind the servo. But, searching these forums as well as other forums, pretty much any reference has this swapped (that is, they put the RX in front of the motor and the ESC behind the servo). Some people even put the RX and ESC both behind the servo.

So, I'd like some thoughts on why people install these things differently. To me, it would seem bad to bunch them all together as it would seem to mean less air flow to keep things cool. And, to me it would seem that having the ESC in front of the motor would keep the wires nice and short and not have to run them under the top brace to the other side. So, why does it seem most people put the ESC behind the servo?

The reason for the ESC, receiver behind the servo is for weight distribution. balancing the car left to right.

Ah, ok. But, doesn't that restrict airflow?

And, would that also be the reason that people put the ESC behind the servo and the RX in front of motor (ESC's being heavier) ?

I run my ESC behind the servo. I have the RX and transponder on the other side, across from the servo. I have an LRP Vector x-12 7.5 and an LRP SXX-TC Spec. The car is balanced nicely and I have no temp issues. Just make sure to cut the scoops out of the body. Its also a good idea to cut some vents out of the rear of the body so the air has a place to go. I would also recommend going with the JConcepts scoopless body.

Put everything on the left side. That motors heavy.

AE should've put more thought into the layout. I really wish the chassis was a little wider and that the body was more B4 looking, and a bit wider to allow more wire clearance. Got to wire a B44 like it was a 1/12th scale car or something.

But hey, if you go all AE LRP everything fits! Thanks AE.

Anyone run a smaller than norm servo? Will a Tekin RS pro fit good like a RS? The RS, a standard servo, and a M11x Rx all fit on the left side.

I run my esc behind servo and receiver on motor side, runs great. Think thats how everone at our track runs it, no prob with weight distribution. I put transponder on top rail along with the antennae.

I got a big fat GTB to fit behind the servo in mine! You honetly need to know how and take the time to lay everything out with these things, you cant just throw everything in there and the find somewhere to put all the extra wires like in most other cars/trucks. Not that I do that, ALL my stuff is custom fit, it's that little OCD in me..

Here is the way I have mine. I have been running it this way for 2+ yrs.

I have a small servo and my ESC is pretty small too which helps. Balance is great.

Sorry for the crap pic.

Looks like your servo mount is a little jacked up on the left side...

I've been doing it for 22 years?

It's a touch out of whack, but it's because I'm using the rubber grommets on the servo cause the mount holes were bored out by the previous owner.
