HPI Firebolt 15T – New Brushed Motor …Breaking In

Our latest Brushed Motor (aimed at our M03 chassis) is the cheap and cheerful HPI Firebolt 15T

For under 10Eur it doesn’t have replaceable brushes nor does it let you open it up to clean it out properly but if it’s good enough for a few Track-Days then we won’t complain!

We’ve only just broke it in using what we would call a “damp cold technique”. We read some posts of people using distilled water (wet) or ice (dry) and as we had an ice pack laying around we thought… let’s try it “damp cold” !

 

We taped some AA batteries together (to reach approx 3volts) and ran the motor for as long as the batteries would last. As they weren’t that new we actually went through 3 pairs of 2 AA. A great way to make sure that when you throw them away, they’re really dead.

The motor was snug inside the ice-pack, held with a rubber band. At the end the engine was nice and cool so we’re confident that it didn’t overheat at all during the breaking in process.

Let’s see if it indeed improves the motor’s performance and longevity, we have our doubts…

Thanks for watching.
