I've only got four kits that I haven't finished.
Revellogram P-38J - just ran out of steam on it.
Academy P-38F - Lab swept it off the table when he had a radar dish on his head, then proceeded to accidentally stomp on it. Beyond saving, except a few pieces like the Ultracast seat. The rest is now a paint mule.
Monogram P-47 - Was having a blast with this kit until the decals went seriously screwy. So bad that I'd have to completely strip the kit and start over. Maybe one day...
ICM LaGG-3 - Lost one of the rear cockpit windows to the concrete monster. Never have managed to find it. It's funny...I was planning to build it without the canopy, since the glass in those things was so awful they often as not just took it off, but that little bit of side glass HAS to be there. And it's what went missing. The thing is still in the box, being sad.
It's rare that I just start a kit and then put it away. I've found that if I can power through to the priming stage, everything usually goes fine. Unless I try to use 20-year-old decals in god knows what condition...
