Did you account for the weight you are going to add to get the FP motor to an equivalent spec of a CIM motor? Unless your application requires ~15000 rpm at w/e the output torque of the FP is theres going to be some weight gain there.
Sure there will be weight for the CIM too because not too many applications are goign to use the CIM at a free speed of ~5000 rpm, but to simply get the FP to be similar in speed and torque as a CIM it will require a signifigant amt. of weight.
I agree with JVN on this one, given the choice of FP or CIM I would go CIM everytime, regardless of any kind of weight gain. The reliability factor alone is worth it.
