i remember seeing a NASA type article about a remote spyplane, it was designed for efficency and had the volume of the plane controled from nose to tail. the pic of the plane had a graph next to it, bottom line was plane nose to tail, side line was volume, over all the shape ended up being damn close to a wing section, ie, smooth and bigger in the middle. on that graph it had coloured ares that showed what part of the plane was causeign that volume, this meant they had the jet engine intake just behind the wing on top of the plane to bulk out the FUZ before it got to the tail to keep the graph smooth on top. quite how this works as not all of the plane flys though the same patch of air i dunno. but NASA like it.
also some plylon planes have a bit that bulges behind the wing, i think is to get to the fuz width rules, but behind the wing seams to be the fave place to put it, maybe acts like wing fairngs or relates to the stuff above??
PS, saw a pile-in racer lastnight online that had a swept forward V tailplane, more efficent apparently

just saw your reply Ollie
sounds like the plane is comming from AKMacs render, swapping the taper on the LE to the TE with more or less straight LE and less taper on the wing.

just a note on sommit i've got floating in my head, i might be doing a delta soon, was gonna be DF, but the engine we have isnt sounding DF after all, so a mid mounted pusher is plan B, most of the engine is hidden in the fuz, so the nose can be sharper and smooth.

Oille while your looking,... does it matter if the engine is mounted forward or aft of the CofG? aft sounds more pitch and yaw sensitive to me...
