Default Glow Plugs for Ofna Hyper .21

I just got in my new Hyper .21 (part #53211) and I'm confused about the recommended glow plugs - I'm new to this. All of the documentation and says to use a "long plug without idle bar - medium or hot". It references Ofna #51011, which isn't a Turbo plug. But the plug they included with the engine is a Turbo T5. I've just idled it but it's working fine. The engine also says it's a turbo, so I would think it should use Turbo plugs.

Don't these have different thread patterns? It looks like forums say a popular plug for it is the O.S. #8 but I'm not sure if it's the same model or the turbo issue.

Yes you need a turbo style plug. Check out the Odonnell 97T.

The engine (part #53211) uses a standard glow plug...the "Turbo" marking on the pullstart housing is a reference to the one way bearing holder.

The OS 8 plug will work fine in the above engine...but it is a shorter length than is recommened...plugs of normal length would be Odonell 277/288...

There is no possible way to screw a "turbo" plug into a "normal" plug housing or vice versa..
