No sweat bro. The advance 40 is a great plane. Just make sure to epoxy the tail feathers on instead of just bolting like the instructions say and seal the hinges on the ailerons and elevators. This plane is a little heavy for a .40. I would say a .46 BB is the minimum motor I would recommend. My motor of preference for this plane is the Webra 50 GT ( not a beginners motor and a tad bit expensive).
