The Resistance X-Wing Fighter is one of the better LEGO sets my son has built this year. My son is nine years old, so he was able to build it in five hours. Compared to the Millenium Falcon, he thought this one was a cinch to build. The most difficult part to build was the nose piece. There were many pieces that required accurate placement.The PROS:1) There are two wings on each side, and the bottom wing flaps up and down as my son flys it in the air. There is a rubberband that links the two wings which allows this movement.2) There are six torpedos (two red ones on each wing that can be engaged simultaneously and two smaller ones by the cockpit). It comes with extras in case they get lost.CONS:1) It could be made to be a little more challenging. The age bracket is 8-14 years old. I'm only saying this, because for the money spent, I was hoping it would require a longer duration for the construction phase.2) One of the back burners falls off when my son flys the Fighter vertically.I would recommend this set, because my son really has fun with it. It is pretty neat watching the lower wings flap as you fly it.
