 Examples include the Rotary engines from the Fokker Dr.I and Sopwith Camel, and the Spandau and Lewis machine guns from these kits respectively.Hasegawa has found success in producing kits of subjects that were somewhat ignored by the larger model manufacturers.The quality of these kits can vary from very simple construction with few details, to those with very high fidelity, rivaling Tamiya or Revell's best efforts.
