I agree with you guys about separation of RX and VTX, but I see no advantage in putting the RX itself out on the wing.
The OP is talking about the Skywalker, and let's assume the wing is removable, so there are quite some cables to (dis-)connect when attaching/removing the wing. At least 3 and up to 5 if pan/tilt is installed. Depending on how far you have the RX out in the wing you need either to disconnect on the RX which requires to remove the wiring as well or have a second pair of connectors on the wing center.
Another thought, servo connectors are all the same, so there is a good chance for mistakes when you connect them to the RX, hopefully a pre-flight check will discover prior to take-off.
I have 4 connectors, 2 MCX for antennas, one MPX for aileron servos and a third one for VTX, all different and can be plugged only in one way.
Just my 2ct...
