Very cool Yak. I have been using Solid Edge (at work) for years and consequently designed a pattern plane:

Your Yak is inspiring me to start on an Extra330s. I know it's already been overdone but I think with a little tweaking it could be made into a fine widebody 2M pattern/scale/IMAC plane.

I spent most of my childhood drawing pattern planes...(dad flew pattern....pheonix, tiger tails, etc.)...I never did outgrow it....

Great forum....
