Like many modern ARF's the Escapade has a 2 piece wing. Generally this is done to make transport of the wing easier, but the Escapade is a pretty small plane. It is not necessary to glue the wing halves together, they will not come off in flight. However if you have the room to transport the wing as one piece and if it gives you piece of mind you can glue them together, like MinnFlyer says it's up to you. But it's not necessary.
