That's the Revell Bf-109G10, right? That's a challenging kit in a few ways, but that canopy glass is the worst fitting of any I've built yet.
I'd like to try building it again. They're always better when you know where the problems are. :)
Yeah, that's the G. A lot of putty and the canopy had it's issues. Just started the Revellogram Spit. It is much worse and haven't even got to the glass. But, hey, picked them up at my local Drugmart for $15. (along with a PT 109 for $10)
