Almost all of the parts are in LDD, but the following are missing:
8x 47349c04 - Wheel 72 x 34, with Lime Tire 72 x 34 Balloon Offset Tread
2x 61929 (BL: bb339c01) - Electric, Pole Reverser / Polarity Switch with Black Lead, Power Functions Complete Assembly
Dont forget some strings for the winches.
You can also make a version with regular hubs and wheels.
