Do I understand correctly that you're complaining about a couple of ratings below a 10?
As pplace pointed out the physics for the PBY aren't the same from G4 to G3.5 and they'll have to be tweaked. That fact alone indicates a rating someplace below a 10, doesn't it?
All of these models, the ones done by pplace and the ones done by willsonman are great models. Why be concerned about a few people who don't think they're perfect? Perfection should always be an unachievable goal anyway. A goal to strive for but never quite achieve. Because once you achieve it there is no more reason to strive for it, no more reason for improvement.
I just downloaded the G3.5 version of the PBY yesterday and changed the engines and props. It does seem to drop pretty fast without power. But, since I don't own one, I don't know if this can be considered normal behavior. It seems to fly very scale and looks great in the air. I'll take a closer look at some of the weights and such and see if anything looks out of pace - if not I'll consider the behavior normal until someone else points out that it's not.
It's too bad we don't have catagories to rate the different models. I'd love to be able to give the PBY a 9 for modelling expertise, an 8 for physics, a 9 for colorsheme ... and a 10 for effort ... etc. Instead we have to give the EA one rating for all of those factors. And then you have the issue of criteria. What judging criteria do we use to determine a 10, 9 , 8, etc? Because obviously not everyone uses the same criteria.
