Does the S-25 use a long or short plug?

[rossb]

I have a couple of new HPI Power Plug #1503 Medium Cold R4 Platinum/Irridium Glow Plugs laying around and I want to know if these are considered long or short plugs. These plugs are recommended by HPI for use in the S-25.

My new Picco 26 requires a long plug and I was hoping that I could use the HPI plugs.

I know that the S-25 does take a standard long glow plug. However I can't find anywhere stating whether that R4 plug is a long plug.

Simply compare the length of the RS4 plug to a plug that you know is a long plug (like the current one out of your Picco). They should be the same length. If so, then you are good to go.

The motor does not come with a plug. I ended up ordering 4 Ofna/Picco medium #51007 plugs from Nitrohouse.com. I also got the 9mm carb venturi insert.
