There’s no such thing as being qualified or un-qualified to “pick apart” an FS model. It doesn’t work that way. Either the “picker-aparter” is correct, or isn’t correct. The very idea that this or that person is “unqualified” (based on what?) to make a comment about WIP is part of the problem around here. We seem to have trouble here isolating the commenter from the comment. If the commenter is “in” then it’s ok. I’ve seen a payware model released a few years ago that was shaped very wrong in a very vital part of the airplane. Somebody pointed it out, and he was raked over the coals for it here. He was correct, but what did that matter? He wasn’t even rude about it. He just wasn’t “qualified”, I suppose. He was even told he was wrong. Yes, the model was fixed.
