Hi,

Interesting review. You say the motor was 'fluid dipped' - what does that mean?

Hi Ken, 
You're opening a big can of worms with that question( which should probably have a separate thread.)
Fluid dipping is an old school technique used to improve the performance of a new DC commutator motor (not brushless)
This technique can also be used to flush the accumulated debris from an older motor. 
Some manufacturer's motors respond well to this,  some not.
The motor is lowered into a liquid for a period of time while running, typically at three volts.

The liquid running beds in the brushes, moulding them to the shape of the commutator. 
The liquid?  Most racers have their own secret special brew. Some use water, some oils or other chemicals. 
Water is a good starter fluid, but ensure you run the motor until it is warm and dry after the dip otherwise you may get rusting on the armature .
Remember to lube the spindle bearings afterward.

Be aware that fluid dipping shortens the life if the motor and is really only a technique useful to hard core club racers. !  ?
