I forgot to tell you.  I am runing 3 blade prop (15.75-13 re-piched to 11) in a Focus I.  It has been the best plane - prop combination for me.  I know tha Bob Pastorello has been using 3 and 4 blade props.  I am sure that he will see these e-mails and give you some more advice.

Good luck,

Vicente Bortone

Would someone send me a chart detailing the different pipe options that I could use with an OS 140 and 160? For instance - 

Manufacturer Model Cost Weight 

Grieves
MAC
OS
etc ...

I have a Focus II coming and need to order an engine. Does anyone know where I can find one? I understand that the retailers are out of stock. Also, of the various props, 17X12, 16X14, 3 bladed, etc., which one gives the best downline braking? Last question is about the header options, what are the costs and sizes of the various ones on the market. When I ran the OS 140 in 1997 I used a Mac header with an extension tube and a MAC tuned piped But if I recall correctly it was a .20 size pipe to simply act as a muffler. I detuned the engine so that it turned an APC 16X13N at 8100. Even that was a bit fast for the plane, a Steve Stricker Excalibur II, which was a big plane at the time. All help is appreciated. 



Thanks, Rich
