5mm bore 48 pitch pinions

Ok I just talked to dan and he does in fact have all the smaller 48 pitch 5mm bore pinions on his site ..I just over looked them. As for "turning down" the shaft he said forget it. I'm going to ask mike to order a 1506/1y (5500kv) with an 1/8 shaft so I can use all the gears I already have because the ones on dans site are very expensive.
