As far as "scaleness" goes, here is my take.

Nearly everybody has seen an Extra in person. Many people have seen an Edge. Very, very few have seen a Yak 54 in person (Jim Bourke's is the only one in North America, I saw Eric Beard fly it at an airshow in 2004).

Exceedingly few have ever seen a Giles/MX2/MXS-R (although that will change with Rob Holland, Nigel Lamb, Gary Ward, and Greg Poe flying the beast in airshows and RBAR), Slick 360/540 (NONE in North America yet), etc.

Most of the models on the market look somewhat "similar" to the full-scale counterpart, but have taken many liberties with layout, moments, to make them fly better. Most of us out here compare the "scaleness" of any model based on the representative models we have seen, and not based on their actual likeness with a full-scale plane.

This plane looks great! Can't wait to see it with some graphics. Are you going to get something going with B&E, Bad Brad, or somebody else as you did with the Sukhoi?
