Mould King 17013 GMK Crane is originally designed by Mould King. It consists of 4460 pieces with 5 motors. It is the very first set equipped with brand new 6 channels batterybox.
Mould King did excellent work in its design and building instruction, it is a pleasant to build and play this giant crane. I do like it!
