What ratio is this????

I have a gear box with a 10 tooth pinion and 48 tooth main gear. Is the 4.8 to 1 ratio if not what is the right ratio? Also what prop should I use on it? The Motor is a mabuchi 280 motor that is used on the minimax. I planed on useing 7-8c on it.

Yes, ratio is 4.8 to 1. Try slowfly prop 10x4.7

Yes, 4.8:1 would be the correct ratio.

You can probably use an 9x6 to an 11x7 APC slowflyer prop.

Good luck!
