Academy's H-60s have a separate engine as well. So does their OH-578D kit and their UH-1Cs. Trumpeter's MI-24 Hind, and MI-8/17 Hip do as well. All the above are 1/35. Revell's old 1/32 UH-1D/H, OH-58C (Jet Ranger), and AH-1G Cobra also have so-so engines. Monogram's 1/32 Puma does too. I don't know about other scales since I don't build them.
