This is a 1/96 scale paper model of the chinese DF-3 and DF-4 missiles. The DF-3 was the basis for the later DF-4, and was the first stage for the later missile. The DF-4 was the origin of the Chinese LM-1 space launcher. Both models are in the kit, and are well detailed. the DF-3 is a one-stage rocket and is fairly simple. The DF-4 is a two-stage vehicle, and has both stages well detailed, including second stage engines. The kit is overall a 3/5 for difficulty.
