This was one of my first mods. It isnt all that. It runs close to a 2.2 on a bitracer axle. It does have better torque, but it doesnt blow away Micro B motors, esp anything 2.2 and up. I have taken apart 9 different pagers, and tried the ones that would fit. Older pagers use larger diameter motors similar to the OEMs or the GP microcycles. Thus they cant be used on bits, because they dont fit in the motor well. The newer pagers are all standard in size, and fit with a little wire fiddling. I have to use a black 6 tooth motor gear with bitracer axles to get the gears to line up accurately. They dont just pop right in either. they are slightly longer, and its best to put them in flat side up. They arent cylindrical. Some are.
Actual RPMS in chinese manufactured vibrator motors only run between 6-11K RPM. Anything higher isnt necessaryfor a pager vibrator.
