For breaking in a brushed motor. The best method is to run the motor on low voltage (less than 3 volts). Start with a drop or two of oil on each bushing or bearing and a drop or two of comm drops on each brush. About half way through the break in add another drop or two of comm drops.For a sealed can motor like a Tamiya Mabuchi Motor, run it for at least 1 hour. For a rebuildable brushed motor with stock or upgraded brushes, run the motor for about 30 minutesIf you have a motor mount to hold the motor, add a small fan to the motor shaft to blow air through the motor in order to keep it cool.When finished clean the motor with electric motor spray, and re-oil the bearings or bushingsAdding one drop of comm drops before a run will add a little performance, but brushes will wear quicker.Features:Add drop or two on the commutator every run will increase power. Great to use when breaking in your new brushes. Lubes commutator and keeps brushes from burning. Comes in a 1/2oz (15ml) Needle Tip Bottle
