Cheers Nigel, glad you're also having fun with this one

It's now on it's undercarriage - hooray. As promised here's the tailskid with bracing struts added using 0.4mm brass wire (I initially tried bending these as a pair in a 'V' shape, but found it was easier to make them up individually) Bit of touching up to do, but pretty strong and looks the part

And at the front. Fairing shaped from 3 bits of plastic card around a brass wire axle and bungees from stripped electrical flex which can be wound around and holds in place without glue. The two bracing cables can be seen floating loose and so can the fairing over the rear spar. The decals, incidentally came from and recent AIMS 'RFC Roundels' sheet and can be heartily recommended - they just behaved exactly the way you would expect decals to and settled down nicely with microsol and set

Sadly in a bit of an arrrrrgh moment I managed to pull out the inner rear pair of flying wires where they join the fuselage during the process of doing these bits

(remember what I said about Sharpie coloured fishing line not sticking as well as it could . . .) Anyway I put the model down and left it overnight whilst I had a think.
Picking it up this morning I couldn't see a way of getting them back into the original holes and under tension but I realised that I could just about drill some new inner mounting points through the gap in the wing root and some careful measuring from the top of the wing meant I was able to drill though from the top and get a new pair of holes for the wing mounting points. Cutting the old wires free means I now can replace them, hopefully without twanging any others . . .
Having put the model down I decided to concentrate on someone to fly this thing. An almost suitable Austo-Hungarian pilot from Peddinhause was slightly modified with a long 'RFC' style flying coat made using Miliput/Duro putty mix with belts from tape glued on with PVA. Lacking gloves a pair of large gauntlets were sculpted using some spare putty (which actually took longer to make than the long coat) I'll place these on the lower wing later as if he's just preparing for an evening sortie.
