They work pretty well the modular part gives nice wingflex with FAR. I would recommend that put slots for the control surfaces instead of attaching them to the trailing edge, and some snap points on the bottom if you decide to do custom landing gear.
If I may ask could we also get more inward folding gear with tilting boogies and covered shocks, Ie: the likes of the 767?, I understand that animating tilting boogies can be hard so this doesn't have to be a top priority.
