Sure looks nice. A few thoughts...

4 strokes are heavier than 2 strokes, and have great torque for all the trick 3D stuff. Personally I would look at a Saito 80 or better. Batt & receiver to the nose, try pull - pull on the rudder (if you dont have it already), light tail wheel and assy, Aluminum nose cones are heavier than plastic (and look better) and possibly mount your throttle servo farther in the nose if you can.
