No, there isn't enough room between the rear gunner floor and the bottom of the compartment to get the tank back there. I found a spot in the wing that it will fit in though, right behind the center flap servo. I'll just have to run the pushrod around it. The servo bay for the bomb drop and retracts will be on the other side of the main spar, between the wheel bays. Since I can't drill into the spar, I'll run all the air tubing and bomb cables under it through the center plastic piece. The air fill will be under the bomb.
