Yep, Allison Engine Inside. Don't think there are any more of the old Klimovs around.

@blownglasslide Are there any with the original Klimov engine around today?

@lemonite1

Yeah, a guy in Russia is using one in a MiG-3 restoration. I've heard it's been giving him a lot of trouble though :/ I hope he gets it airborne, I'd love to hear what an old Klimov has to say :)
