My favorite plane of all time is the De Havilland Mosquito. The Whirlwind is closely related in design, so I reckon I will give this build a go next year sometime.
When its completed and I get around to flying it, I will post some pics and a video.
When it comes to design and plans I am old school: Pencil, Paper, Protractor and Drawing Compasses.
So if you wanted a copy of the plan, I would have to get it scanned and email you a copy !
