Ive now hovered 9 packs through my new DD tail motor and its still sounding pretty good. No noticable loss of power, no glitching or unexplained noises etc. Im still pretty happy with this setup so far. When I bought the tail motor it already had 2 leads from it with a small JST like connector on it So I then soldered the opposite end onto the wires from the 4 in 1 onto this and I can simply plug in and unplug motors when I change them out. All in all I still think this is a step up from stock.
