I'm trying to resolve a discussion regarding the A model three-bladed props. I flew A models (53-3133, 55-0022, 55-0024) in the 1970s at Hanscom Fld, Kirtland AFB and Wright-Patterson AFB in A.F. Systems Command. My recollection is that the A model three-bladed props had synchronizing, but no synchro-phasing. I certainly remember the "prop beats" flying them, the the super quiet of the E model when we got one of them. I've researched Aeroproducts web site, which seems to imply they were synchro-phased. Can anybody confirm or deny my recollections? I wish I had kept my A Dash-1.
Thanks in advance,
Ralph Brands
