Brad, Greg lists the Cox .09/.074 turbo head. Is this what head is on your engine? I have 3 Norvel .074 engines. Two being the heli engine which I removed the large beehive looking hairdo head. Is the thread for the Cox .09 the same as the Norvel .074? I could check but I would have to dig my .09's out. The .09 isn't a engine that I ever use, I have them in a bag in the back of my cabinet somewhere. This whould be great if they fit because I have a well seasoned .074 that's r/c that I would like to use but the head is burnt out.

Unfortunately the Cox .09/.074 heads are not compatible with the Norvel .074 engines. It is only the Cox .049/.051 heads that are compatible with the Norvel .049/.061 engines.

While I won't dispute the cost of Rhodium, I'm finding it hard to believe that manufacturers even use it for several reasons. One being that it's toxic and another being the cost . My club member Andre flies F2D and makes his entire engine and glow plugs. I'm well aware of what the precious metals do in terms of providing a catalyst but the plugs I know he's making I believe are using nichrome wire and I can almost bet that's what Fox used as well. Other plug manufacturers are still selling plugs at a reasonable price so someone is certainly blowing smoke here. Given Mecoa's track record  I wouldn't take anything they had to offer to be credible. Nelson plugs in my opinion are the best plugs made and they're still $5 a piece. Nelson plugs are the standard for most high performance engines and Henry still makes them. He told me personally that no manufacturer will EVER make a Nelson style plug cheaper than he can. Platinum, Iridium, Rhodium may have existed at one time but as all business practices, when it comes to $$$$$$$$$$ nothing matters to them aside from saving it.

Are the Norvel .074 plugs of the insert type? I have The heli motors that came without a glow plug. I was thinking of making an adapter for the standard or turbo plug but would still need the clamp.

Y like To hear fead back on the parts mecoa made adapter for the norvel if is the insert loss power or gain ? Y nead some of them for future build y just wonder if giving same power rpm range ?? Cool vidéo mauricio
