It is a fair concern. This is a guy in his garage (albeit a VERY sharp guy) putting together a one off. I think the key here is that this is a niche rig. The two in my opinion (Foxxboxx vs SkyjibX4) are very different machines and are only comparable because they are multis. We need something that deploys up and down quickly and goes on an airplane. We have a very specific payload and it really is a custom solution. We're finding the vast majority of our Clients are looking for smaller lifts not heavier so it makes sense for our business model. It might not for yours. Seems like everyone is building bigger (ourselves included, we fly a flat Skyjib as well) but you might be surprised at how much/how often you really need/want to risk on every flight.
