DevFus 2: Wing slots
Using this panel you can add optional wing slots to your fuselage. You can use this to apply also different slots, for example for the tail stabilizer or for wing joints.
A Wing Slot is a slot in the fuselage that can affect lateral sides, Formers, Shaped Spars, Decks and Boxes. You can use this option to add slots not only for wings or stabilizer, if you like.
For example you can use it to make space for a connecting spar.
