What size prop is this????

[dru]

I have a prop off of the Cox Viper and I would like to know what size it is. All that the prop has on it is 108. It is 4 3/8' long and on a guess it looks to be about a 3 or 4 pitch. I would like to know so I can get a little bit bigger one for the Highway Patrol conversion I am using it in. The motor seems to be under proped.

I know what a prop is when it says 9X4, 12X6 and so on. But when it has just a number, I dont have any idea.

Thanks for the help.

DRU:
That could be the size in cm., 10cm.dia.x8cm.pitch, or roughly 4"x3".

Thanks!! The light bulb goes on. I think you are correct, I chacked the pitch again and it is allot morre then 3 or 4. I think I will start off with a 4.5 prop and see where that leads me.


Thanks again.
