Header for OS 140RX
 

Is the o-ring header important for this engine on a hyde mount, or does the solid MACs headers work ok? And, does anybody have one for sale?

MAC header works fine. I prefer the Karl Muller headers though. The headers with an O-ring are a pain to deal with.

Hi,

In my personal experience the O ring headers are not necessary. I have read many different reviews
and I they are much more hassle than a macs or a mueller header.

I have 2 - OS140rx using both macs and mueller headers and have had no problems with either.

I dont have one for sale but for those that may, what size offset header are you looking for.

Cheers,

Elmer

Hi,

I ordered a solid header from Lorentz in Germany. Works great. I cut mine in two pices so it could flex a little as the engine sits in a Hyde mount.

Hey Keith,

Good to hear from you. I am finishing up a Temptation. Its pretty much ready, when I get the engine set up. I missed contests last year due to other commitments, but once pattern planes are in your blood, I don't think they ever completely leave. Just stays dormant for a while:)

I had excellent success with the OS headers when I switched to Nitrile O-rings. I got them from my local bearing shop. I'm not sure but I think this material handles the fuel and temperatures better.

In any case they've worked for me. Prior to switching over to Nitrile, I found that the standard o-rings kept popping out, splitting etc.

The other thing I do is treat them as disposable items. What I mean by that is that if I adjust the header in any way or remove it , it's time for new o-rings. They seem to last longer when left alone.

Wingster,

I sent you a private message. Did you receive it?
