I'm planning to upgrade my Fireteam to a max6 with the 5687 motor and I see that I'll need the 56 series sliding mount to get the screw holes 30mm apart, but I'm still worried about whether or not there will be enough space vertically for the motor to fit since it'll be about 1.6cm wider than the stock motor. I've seen in other threads people recommending the PPS mount, but I guess if I can get the current mount to work with the addition of the $20 larger sliding section I'd prefer that since it'd be a bit cheaper. Has anyone else done this?
