One of the finest technic models.

Do not put the covers on the block batteries for not having to disassemble at every change. Otherwise just remove the shroud and pull the red 5 pieces.
The plane is really good, there are many different mechanisms in little space. Shutters, drift, direction, and the motor that drives the choice: propellers, train landing, the rear ramp or nose rises. It is beautiful and large, it take the place elsewhere.

One regret though: the new Lego Technic with their non-stackable beams are much more complex to understand than the old ones. The models are more beautiful but it is very difficult to design their own constructions.
