You mentioned " if I were to make a motor mount...", so I guess you have the means of fibricating a mount. I did not and could not, so I used the stock mount . I happened to have an old Proboat 1500kv ( from a Fast Tech) , the cooler was on the short side so I slid it towards the back and the front was opened up a bit, I slid the motor into the clamp as best as I can, it will only grab a bit and I used black electrical tape to increase the diameter of the motor can. Just a little till it fits snug.DSCN1907_1397.jpg, DSCN1909_1398.jpg.
