I had some time to build over the weekend and this is how far I've got so far.
I've left the launch assembly unfixed for now to make painting easier. There are two cylinders which attach either side of the drivers hatch, I drilled them out to the wrong size, big enough to fit the pistons but too big a diameter for strength and I'm stuck waiting for a reply from AA about replacements now. There are still things I can do while wating though.
Just realised, only 10 days until Scale Model Challenge, PANIC
