After reading a comment suggesting a design issue concerning the change of battery, I admit I was a little hesitant to order this model. Fortunately, I did not stop there because on arrival, the plane is superb and its functions are very ingénieuses.Mon son of just 10 years feasted during assembly and motorized functions really enjoyed it! For battery replacement, up the nose of the aircraft and 2 by removing side panels, easy access to battery box which can then extract completely. The operation take 3 minutes in all. Simply excellent!
