I have an SC .61 engine to go into a Modeltech CAP 21 Plane.
Does anyone know much about these engines? What sort of glow plug do I need etc..?

Thanks.

Should be in the glow, but its the same as the ASP, Magnum, SY engines.... Run a standard OS 8 plug.... Props from 11x6 to 12x8 or take this chart as a reference...

Is your SC 61 a two stroke or four stroke engine?

I am not sure weather it is a 2 or 4 stroke. How can I tell? Aren't 4 Strokes bigger than 2 strokes? I think its a 2 stroke but I'm not sure!

The four strokes have a relatively smooth rocker arm cover on top and two push rod tubes going up the front of the cylinder.
If you don't know then the engine is most likely a two stroke? The four stroke uses a different glow plug.

Yeah probably is a 2 stroke then! so what Glow plug do I need?

The OS 8 as suggested to the preferred plug

Is your CAP 21 the 59" wingspan or the larger I think 71" wingspan? If it's the smaller one, is it built or still in kit form. If not built would you like to sell it? Does it have a clear or amber colored canopy?
