  5. Hmmmm. Now if we were to take that and drop it into a lightweight, chrome moly chassis...

  6. A very impressive engine, 300hp out of 140lbs. The Allison C250 powered the Bell 206 and Hughes 500 in Vietnam. Rolls-Royce bought Allison about 20 years ago and is still making them. As mentioned previously the helicopter is an Aerospatiale 355 Twinstar and yes it does have elastomeric bearings.

    1. C250’s are weird. Cold air in the front, burned in the back & puked out the middle. And I thought PT-6’s were backwards…. I’ve seen those Allisons dropped into Cessna 206’s.

    2. Looks like it might be one of the LAPD birds.

      The high-time pilots who cut their teeth on Hueys and flew JetRangers for years still complain about the "rubber-band powered" French machines, but they seem to hold up pretty well.

  7. i BELIEVE BELL 206'S HAD C20'S AND THE OLDER MODEL HUGHES 500 HAD C18'S BUT THEY ARE VERY SIMILAR.
