I know there is a lot of information about these MCP's out there as I have been reading quite a bit of it lately getting ready to build a couple for some engines of mine. I played with rc combat for a short 3 month segment when I lived in a town that had a club with combat enthusiasts. I moved to another town and this club is not into combat but heavily into gliders and pylon racing so I got out of the combat business without a lot of experience.

Anyway, when I was building my combat ships, the folks there were using a mouse can pipe set up like detailed in my drawing, using the top method with the one piece header pipe. In all my searching about MCP I have not seen anyone build one like this. They are all the conventional way. Is there a reason for this? The only thing I could think of would be that the header pipe is not supposed to support the muffler weight, however, the can can still be mounted to the aircraft and the silicone sleeve will still isolate the vibrations from the header to the can.

Can anyone tell me why not to use this method for building a MCP. Is there something I am missing in the design of one of these pipes.
