glow plug advice
 

I've just purchased a new Argus A52 engine and JP4 pipe.

The whole glow plug thing is a bit confusing. Can someone advise which glow plug type is best to go for?

Do I need a different glow plug for different weather conditions?

I've run these engines for a year or so now and run Orion turbo plugs in mine.

I know many people also run OS P3 plugs, but the Orion is cheaper, and in my opinion, a better plug (I've never blown one).

I would typically run the Orion No.6, but with the cold weather we've had the last couple of months, I found the Orion No.5 was slightly better as it glows a bit hotter.

Turbo plugs have a tapered bottom, for a better seal to the combustion chamber, whereas a standard plug is square bottomed. With plug numbering, the lower the number the hotter the glow. Hotter plugs (lower numbers) are used in cooler conditions and vice versa.

Thanks MCP. much appreciated.

Who sells orion glow plugs?

Your local model shop should be able to get them.
Mine came from Euro & Asia Models nr Maidenhead.

Welcome to the argus clan this is what we all run and the plug i use are either ODonnel 97 T or OS P3 plugs and no problems with the engine

Search the bay and you will find both plugs at a rerasonavle price especially os p3 from hong kong and you will not get stung on import duties;

Also sometimes get some good deals on Odonnel plugs to i feel no need to pay £ 9 - £10 for 1 plug when these do excatly the same job as i want them to do

Hope this help if you have trouble finding the links send me a pm and i will post the links to you not a problem
