Cheers,
Mine is the ARTF so rx, esc etc all fitted in place, but you are right, with the wiring it is very tight in there.
The lower side of the wing is butting up against the fuselage so it is fully in place but the screws are still several mm away from reaching the mountings. I thought about shaving off some of the styrene but dont really want to be messing with that on a model that is supposed to be RTF.
