When I am judging I have a bit of a time with so-called scale planes that are really just a regular stunter(SV, Impact, etc) with a more or less slightly modified fuse profile. I find that type of plane really detracts from the flight appearance, although I do my best to ignore it.
The more scale planes do make an impressive flight. Most of them I've seen though have a soft corner and tend to fly oversize patterns. Sometimes the impression points cover that up, other times they don't.
