whirleegirl Posted July 6, 2009 Report Share Posted July 6, 2009 I asked around and searched forever for information on the Allison C-20B engine and the Jetranger. All I came up with is that it comes from Bell. And can you buy it? No. You have to go to Bell school. Fortunately, I came across a manual that came from the school. See if you can find someone who went and will rent it out to you for, oh, 200 bucks or so. They are very precious!! Good luck! Quote Link to comment Share on other sites More sharing options...
67november Posted July 6, 2009 Report Share Posted July 6, 2009 best place to start is with RR http://www.rolls-royce.com/index.jsp you'll have to ask them directly Quote Link to comment Share on other sites More sharing options...
AngelFire_91 Posted July 7, 2009 Report Share Posted July 7, 2009 Hello, I have some information on the 20B, but it's nothing real technical. It's just a powerpoint I've put together for my students. It has simple things like how it works, limitations, etc... If you want that then please send me a pm with your email and I'll send it away.

Gomer Pylot Posted July 8, 2009 Report Share Posted July 8, 2009 Allison was purchased by Rolls-Royce several years ago. You need to search for Rolls-Royce, not Allison. Quote Link to comment Share on other sites More sharing options...
