800mah, where did you find the long 2mm flat head screw that secure from the motor cover to top of the hex nuts. I'm making a 98mm like yours but I don't have that long screw.
actually, i am using a round screw,
but i have noticed that it will stick out from the bottom of the motor cover.
all i did was file down the screw head a bit and everyting was okay.
so the screw i was using is actually a long 2mm roundhead screw.
btw, i've switched to a complete GPM DPS for 98mm, will show u tomorrow.
