Thanks Hugh, it's appreciated.
Nearly done (famous last words !), with the gear doors, speed brakes and belly tank fitted.
As mentioned, the main gear doors were a bit of a pain to attach, but got there in the end. I also had a bit of a 'senior moment' when doing the speed brakes. The actuating rams were cemented in place in the bays first, and then painted and allowed to set. Come the time to attach the brakes, and I discovered I'd fitted the bl**dy rams the wrong way round !
Out with the scalpel, prise them off, re-fit, re-paint and allow to set, and then attach the brakes !
Next step was the main leg doors, which went on reasonably OK, but I then noticed they looked very long, covering the entire wheel and almost touching the deck. A quick check of reference photos showed that they shouldn't look like that at all, as the bottom of the doors should be just above the axle point of the main wheel.
So, using the precise method of Mark One Eyeball measurement, the top edges of both doors were cut of, removing 2 mm, and then filed smooth, before fitting them in place without problems, and looking more like the real thing.
Finally, the belly tank was cemented in place, and the model put aside to fully set.
The first pic below shows the modified main gear door on the left, with the un-modified door at right, with the remainder being general shots of how things look so far.
All being well, tomorrow I hope to make and fit the antenna beneath the nose, along with a AoA probe on the starboard side, then attempt to make and fit a pair of rear view mirrors to the canopy rim, before attaching the canopy and finishing the model.
