If im not mistaken i think they all come moass now. you will probably be better off building the moass anyway. it will allow you to take the steps as needed. the more you fly it the more you will like it. the moass mod make the fuse longer and surfaces bigger so even if not doing wild 3d the longer fuse helps it track better. i went moass and did not look back
