Aresti you are spot on with everything you have said.We allow all sorts of non scale things in IMAC(electric motors,up to now an opaque canopy was fine, etc) the 10% rule is also there.The QQ yaks would only just scrape in but scrape in they do.Lets look at the bigger picture not make silly little rules over opaque or non opaque,pilot or no pilot.If we are to go hard line scale then we would all be flying new planes.Unless formula one drivers are flying IAC then those using them in RC planes are not flying scale.I believe that the plane should be a good representation of the real thing from a standoff point of view and then let the competition be decided in the air like it should be.Also until I see a full size extra,edge etc using electric power then that is way off scale in my mind,but given noise restrictions etc it would be a SENSIBLE rule to allow them to fly.
