Hmmmmmm........... Time?? Well, I never timed myself on a kit. I'm really very much an amature and build almost straight out of the box. I concentrate on cleaning up and maybe a few bits of wire here and there. Sometimes I slap one together over a weekend, and other times it's a little here and there. The KV was a weekend project, and the Panther was built over 6 months. It really just depends on what's going on in the real world. At the moment, I have three completed and awaiting paint. It always takes me longer to paint than anything else. It's just whenever I get to them. If you read Steve's Modeling 101, the bottomless pit is MUCH larger when working in this scale, so I do spend a bit of time on my hands and knees looking for itty bitty parts.
