First of all, I am making a new updated 717-200 with working landing gear! I don’t know when I will post it but probably sometime soon. Also I need help with making flaps. How can I make flaps on the normal wing? The only control services available are the Pitch Yaw and Roll surfaces.
Use overload and change the control surface's input to VTOL or whatever you want. If you're on iOS you can do nothing
