This aircraft is quite large and heavy, so that continuously triggers the nosewheel. The 4 engines do not hold very well. The biggest problem, however, is in my opinion the connection between the front part and the rear part of the aircraft, you can open the aircraft yes. This connection is not made perfect, I must now repair the 3rd time. Thus, if one wants to assemble the part once to look at that's good. But that child after play so that not doing so well, why only 2 stars ..
