[SPAM] Re: OS 1.4 RX Header and Pipe installation in Focus II

[Mike Austin]

Bob, I aligned my spinner with the cowling. Not sure of the exact degrees but it's very noticable while looking from the top. Hope to test fly this weekend. BTW, the mueller header comes with the offset already built in too.Makes the pipe line up properly in the tunnel.

  Thanks for that advise, a Mueller header already at the correct dimensions would be nice.  I have the engine set at 5 degrees right thrust; is that where you have yours set?  Was wondering what the group consenses is on right thrust necessary for the Focus II.

    Bob, I just finished a new Focus 2/wOS 140 and installed a Mueller header. If you want the exact size without fussing with bending a Macs, email him at the below. Same price as a Macs and it fits the first time. Actually it's a 3" rise if I'm not mistaken. Tell him what plane it's for and he will fix you up.

      I would like some advise for installing a header and pipe in a Focus II.  I have the OS 1.4 RX engine, the OS 72102100  Header and the OS T-6010 Tuned Silencer.  My problem is that the header has interference with the firewall. I don't really want to remove material from the firewall to gain clearance.  Is there another header that I could use?  My other question is if the OS Tuned Silencer is the best choice?  I also would like to know what the length should be if the tuned silencer is used.  I am planning to use an APC 17 X 13 prop and Magnum # 1  2 cycle fuel (approx 23% nitro).  All suggestions are welcome.
