So with the Minifan 480 having room for 27 mm motors.
The Hacker B40's will fit and also the FUN400 and FUN480.
Hacker 40 ..S 27,6 mm and 125 gram
Hacker 40 ..L 27,6 mm and 155 gram
FUN 400 28 mm and 110 gram
FUN 480 28 mm and 145 gram
The Fun 400 is a speed 400 dia motor, you need to shim and support the rear of the motor in the MF-480. The Fun 480 I belive will fit snug in the MF 480. I am not aware of anyone running Fun 480s in the MF,,, I dont know why, overkill maybe???
Don't know what you mean.
As for the link to the Kontronic homepage, i have been there.
But the links called "Maße" where i would find the specifics on mesurements have been dead for a long time.
But i'll take your word on it that they are both 28 mm dia
