There was one fit problem I encountered. Part H15, the upper left side engine cowling, dry fit perfectly. But, my engine must have been out of position as it never even pretended to fit after the engine was installed. It is heavily modified to even remotely fit. If I built another one, I would add this part before assembly. Then I would see where I made my mistake with the engine.
And Tim, no models in the case will be replaced by this model, although I do have this color scheme in 1/72. This model is for my long time customer. He gives me green pieces of paper and he has to find a place for it.
Progress is going well. After 5 stops, I finally found the adapter for my Iwata and it sprays beautifully. I may post some pre-paint photos today.
