I am looking at using an Aeromatic wood prop. I know a guy that makes
   these propellers and he has a lot of the original hubs to build props
   from. He tells me that the 8 bolt pattern is not used much (I think
   they were used on the Franklin engines) and he will let me come in
   and build my own prop with one of these 8-bolt hubs. Will the Ross
   copy PSRU's be built so that flange could be drilled to accommodate
   the hub?

   BTW. this guy has been experimenting with the original Aeromatic
   design and he claims to have made some improvements that I think are
   fairly significant. He claims that IF, IF the prop is adjusted
   correctly and IF the engine is turbo normalized, he can make the prop
   work exactly like a CS with the exception of no cockpit controller.
   For non turbo normalized engines he has an altitude compensating
   adjuster device that will automatically correct the propeller
   adjustment to compensate for power loss at altitude. The altitude
   compensating device has not yet been flight tested though. If all
   this is true it might be worth looking at. No hollow crankshaft, no
   prop governor, no electric controlling system. I don't know the
   weight but he claims it is about half the weight of a CS. he sells
   them installed for $5350. Not sure how this measures up to the
   electric composite propellers.

   Yes I can do that as in the Ross design the prop flange is a separate
   part.

   Mr. Shamlian,

   I would be very interested in contact information for this individual
   who is improving the Aeromatic design.   Thanks.
