The plane is correct. there is no hatch on the 4* series plane. You should be able to get the tank out through the former where the wing dowels fit in. I have pictures of my set up at home. I'll e-mail them to you tionight unless someone posts sooner. My battery is a flat 4 configuration and I positioned it under the tank floor and the receiver is right behind that. Servos will be inverted for normal flight. I changfed the gear on mine and went with the fibreglass gear by dubro,
