Have refined the mesh to reduce the size.
Now down to 3100 polys which seems better at this stage.
Need to make more progress on the basic model now.
Tailplane needs a bit of work to refine the shape and the rear fuselage although nearly right needs the corners to be slightly more rounded.
The 3-view plans don't seem to match the photos of the rear fuselage.
Also probably need more polys on the leading edges.
Junction of fuselage and rear gunners (both upper and lower) needs to be finished.
I have collected a lot of photo data now.
Probably the best photo ref. is Hampden Squadrons by Mark Postlethwaite.
Some valuable detail stuff was sent to me by Nils Hjelmevoll --- Thanks for that Nils.
I've also got copies of various assembly line shots showing the frame structure.
I now have a good set of internals for each crew position, including Pilot Notes, which provide details of the cockpit controls and flight performance data.
There is an existing engine at the Solway Aviation Museum which I will go and look at soon since the view of the engine in the cowling is quite important visually.
Still keen to add to the data if anybody has any detail shots of anything. I have plenty of general views though.
I did get a chance to see the remains of a fuselage and wing in the workshops at RAF Cosford recently but wasn't able to get up close. The workshops were like an Alladins Cave of aviation history.
