I think 16 cells will get you almost 15min, depending on the gearing. mod 1 is bigger teeth. when you say "bore" that is the inner diameter of the pinion. 5mm, 4mm, etc. the xl motors are 5mm bore. 32 and mod 1 are the "pitch" of the pinions. So the 32 will be smaller teeth. I raced with a 10xl, it was ok on 16 cells. the 9xl will get you more speed, but I think the 10xl may give a better run time, not sure on that, someone else can chime in.
