I doubt that the 52T spur will work since the 25T is already uses the smallest motor position for the 55T.
So, without making anything custom, does anybody make a 26T or 27T 48P Metric Pinion?
http://www.robinsonracing.com/catalo...tchpinion.html list the pinions up to 35 teeth in two types and 28 teeth in other types.
The 52 tooth spur will only work with 28-31 teeth pinions.
So yes you need to find pinions first.
http://www.rcplanet.com/Pinion_Gears_s/734.htm Lists them all.
Whether it's metric or not, even if the two terms 48p and metric should be used in the same sentence is debatable .. "metric .. 48 teeth per inch" .. I can not emphaticly say if it is or not.
Check out the 48pitch,64pitch thread for a discussion of pinions and pitch.
