Hello; Welcome; I enjoy building too, but I want whatever I build to fly. My neighbour has an unflyable Airsil Beaver, beautiful build, but it won't fly. Another flyer built an Airsail Auster AOP, another beautiful build, but it couldn't be made to fly either. Both these planes were very well built by experienced builders, but both became statec planes rather then re-engineer them. I have never seen an Airsail Chipmunk, but I have been flying my Goldberg Chipmunk for 3 years, and it is a wonderful plane, and excellent flyer. I'm not saying that you won't be able to fly the chippy, someone must be buying and flying these Airsail kits. I know that some people buy kits just to build with no intention of ever flying them. Airsail kits are great for these people.

Of course your experience may differ.
