Fisher price for the drivetrain?

[writchie]

Beware that the 9015 motor for 2009 ( and 2008 ) has significantly less power than those of earlier years. This years motor has a peak power of about 180W compared to 337W for the CIM. RPM on the FP's is about 3 times the CIM. You can turn an FP into a CIM mounting "thing" with an Andy Mark gear box. This might have sense for a drive motor (or 2nd drive motor) with the older FP's because there power was as least at a similar level.

The FP motors are fan cooled and so they need to spin. They easily overheat and when they do the plastic mounting slips making matters worse. You don't want to be anywhere near the right side of the power curve.

Generally, its better to use CIM's for drive motors and the FP for other things where you have better control over the speeds/loads etc. This year, you most likely need only a pair of CIM's leaving two for other uses.

If you do end up using them make sure you do the math. Also try to rig additionally cooling and make sure you have spares.
