You are absolutely right about the brushed pump....if yours is like mine was, the coupler is off-centered too and it wobbles. It sitting in my junk pile. I bought the brushless the same time i bought the unit. I also junked the valves too. These valves are from tawain. they work great. I drilled the open from 2mm to 4mm for a better flow. What you see in the vid is after the mods to the valve block. i cleaned the threaded area REAL-GOOD and applied TL to the nipple and let set....no leaks there and no leaks .....so far from the heads.
