I had the opportunity to visit the London, Ontario factory on several occasions about twelve years ago when they were going gang busters building 20’s and 40’s. You can’t imagine how well built these aircraft are until you actually see it. The whole operation top down is very impressive, or, at least it was way back when. The people couldn’t be more friendly and accommodating. I don’t know how it its now, but, ten twelve years ago I had no problem getting a factory tour just about any time I wanted. If anyone is able, I strongly suggest calling up Diamond or e mailing them to try to get a tour of the facility. Even if you do not fly a Diamond, it is definitely worth your while. My bet is, if you have ever been on the fence regarding a Diamond aircraft, you won’t be after the tour.
