Hey Si, Well you saw mine at the weekend. Thats how Adam wired his too and his was SXX.
As for the servo wire. Mines pretty long (ooher!) So it went better, exiting from the receiver side, and going all the way round the back of the servo, to the motor side, and back in front of the servo to the receiver....if that makes sense. lol it created less 'bunched up' wires all in the same place.
You can always shorten it and take it directly to the receiver. The wire will fit rount the servo saver posts without it affecting the shell fitment.
I'm actually going to re-wire mine...again. Cos I got quite a bit of interference in the final. But its a case of suck it and see. If it fits then its good, if not then try again. lol
When I've re-wired mine I'll post some pickies.
