Well thanks for the positive reinforcement of my idea, however in drawing up the plans, I just can't get a clean way of placing the landing gear in front of the spar. I want the nacelles to be just big enough for the fuel tanks. The retracts have to go in the nacelle rib gap or one gap outward. Either one of these will put the retract or the wheel in the way of the fuel tank. If I move the fuel tanks forward to allow room for the retract, I start getting too far forward with the engines. It looks like I might just have to go with trike gear anyway.
