I run a 96 tooth spur gear it covers running blinky and w/ timing.
17.5 blinky try FDR's in the range of 3.7 - 4.2. It really does depend in the motor and driving style. Make sure to turn up the timing on the motor.
I run a Ballistic with timing at 45deg (3 ticks above 0\N). FDR for this motor on a large (> 100' X 60') open flowing track would be 3.8 or 3.9.
As always set gearing and timing on motor, run for 3 minutes, check temp. As Hanulec mentioned use a heat sink with a fan attached or a fan mounted to the chassis behind the motor.
