Thinking about this some more, and ignoring issues like liability altogether, the fundamental question comes down to this: How does this company make its revenue? If you make most of your revenue signing on new customers - plans, parts, materials, build-support - then you have to keep the number of "kitsters" to a bare minimum, allow them on each customer's site the absolute minimum amount of time, and keep them moving to new customers as often as possible - and somehow keep the shipping distances as short as possible. If, however, you make the bulk of your revenue by renting out shops, then you want the opposite: You want as many shops out there as possible, on each site as long as possible, and ship them as infrequently as possible. Now the business is more akin to really expensive, labor-intensive apartment rentals, rather than a traditional kitplane business. Cost of shipping and maintenance become the things you want to avoid. And you can also branch out into other kinds of shops - boat-building, general woodworking, metalworking, etc. Start thinking of renting to "maker" groups. Small businesses that suddenly got a big contract. Anyone who suddenly needs "more" shop capacity for a closed-ended period of time, and doesn't want to buy the capacity outright. For the specific kitplane case, selling kits becomes just another marketing incentive. You practically give the plans/kits/materials away, just to get new shop rental contracts. Interesting thread. I think the traditional kitplane business models are going to change. I think they HAVE to change. Not sure this idea is the way to go (and I'm also not sure it isn't, depending on which model above is used), but it's an interesting idea.
