This should really have read " without a 5th bearing". I'm one of the guys that had a failure of the alum. cam gear at just over 250 hours without the 5th bearing. Ironically there was no 5th bearing readily available at the time and my plane was scheduled to have the prototype installed after the trip that it failed on. I try to remind everyone at every chance I get that the crankshaft is not the only point of failure that has an impact from the use of a fifth bearing. The cam gear is a slow developing failure that oil analysis if likely the only way to detect. But trust me on this one when the cam gear fails the engine gets every bit as quite as when it is sleeping in the hanger. ?? I currently have about 650 hours on the prototype BTA. I will probably take the engine apart in the next couple months and if Dan wants to examine it I would return it to him to check out (although we have not talked about it yet) So to anyone that will listen ... put the dang 5th bearing on the corvair. Roy's or Dan's doesn't matter to me.. just do it. Joe Horton N357CJ
