Mould King 13122 Swingloader Speed Build

or to find more information about the design. Thanks to D3K&great work. This set is really fun to build and play. The mechanical structure is compact and smart. Way better than LEGO 42030 Volvo Loader. An extra power functions receiver is needed if you wish 5 actions work separately, otherwise wheel turn and arm turn will act together because Mould King battery only has 4 channels.
