Thanks for that.....
S_Ellzey: The reason I was asking about all of this was:
1) I did just buy a RAM 1000 from a member here, and it looks great. It's smooth... all the parts work, and it has a brand new ECU. (This was a great change, as my last used engine was cr@p !!) When I get a chance, I will get the S/N off the engine, and contact Carlos to see if he has a history on it.
But, reason #2 is... I have a buddy who has been buying parts to get into flying turbines... and I bet he has a dozen ram engines, in all different stages. (A couple OK, and a bunch of parts) So... I figure I can learn what I can, and help him get up and running.
SO.... does the Wren wheel have Wren makings on it? (What would I be looking for?)
