I know that Macs has header with different rises than the OS. I
have a 2 1/4" rise header that I got from them that I run in my Eclipse
(s). Just my opinion, but I think the 23% nitro is not necessary at
all. I would not expect anything as far as better performance over
15%. Also, the 17-13 might be more load than it likes, especially when
it is new and you are trying break in the motor. I thought the 17-12
was the best 2 blade prop, or a 15 3/4 - 10 or 11 3 blade APC
"Lockhart" for an awesome combination.<br>
<br>
Also - check out Ed Hartley's web site for lots of other OS pipe - prop
etc combos<br>

<div><font face="Arial" size="2">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.</font></div>
