The old kits were designed this way and lacked room. The newer redesigned A-4 used saddle tanks. Mine was a blast to fly. Take Chris' advice and you will have a long lasting plane.

Another tip....this model is kinda squirrely on the ground. (At least mine was) On takeoff, advance the throttle slowly to get the model moving straight ahead. Once rolling, nail the throttle and off she goes! If you try to advance the throttle full bore from a dead stop the model will try to swap ends. Was mine the only one that exhibited this behavior???? Once I learned how to manage the takeoff, this wasn't an issue any more.
