I've built this one before in the A8/F8 version, and the sprues are the same, only with an extra one for the F8 version. The curious detail is that while the other box used the same parts for the interior of both versions, this one uses a different interior and canopy for the A8 version. Appart from that, just remember: the lip that will come out in the engine, on the front, it is meant to be... I had sanded it in my first model, because I thought it was a mistake... Again, Airfix in its best shape
