Testing
Installation
was easy thanks to easy to solder on tabs, trimmed down
overall size, and plug in sensor wire. According to LRP,
The Precisensor™ System positions the sensor (standard
sensor wires are used) for best power, throttle feel, and
efficiency and is fully adjustable and replaceable.
Now, this may
seem like typical manufacturer bells and whistles, but a
closer look shows that this feature is quite unique. On
most motors, you adjust the timing by simply loosening
three screws and rotating a plate; however, LRP takes a
different approach. The sensor on the Vector X12 6.5T BL
is positioned in the middle and the motor is constructed
in two main parts with four screws. This construction lets
the user leave the motor in the car while changing the
rotor (a 12.5mm sintered rotor is standard). It also makes
it easy to switch out the sensor insert for different ones
(not included) to change the timing in the motor. They
come molded and the timing is preset, but with different
inserts available, you should be able to find the timing
you are looking for. The motor can be operated with sensor
or sensorless speed controls for more versatility. The
unique can design also includes some pretty big vent holes
to help increase airflow.
I set my gearing according to the recommendations in the
manual and hit the track. The layouts at Bending Corners
Raceway in Orange, CA tend to be a little tight and
technical due to the size of the asphalt track. Although
this motor is only a 6.5T, and I ran with my car fitted
with a two-cell lipo, I found the motor to be very
powerful and smooth. I could have run a lower turn motor,
but this thing was plenty fast for this track. I left the
standard straight insert in the motor, and since I didn't
have the other angled ones, I was limited to the box
contents for testing. To be honest, I never really felt
like I needed to change it out, and I would mostly make
changes to my ESC instead, but it was nice to know that I
could change the insert if I wanted to.
What I and many racers have forgotten is that today's
technology has made motors like this extremely fast, and
I'm sure the Vector could keep pace with the fastest
brushed motors from only a couple of years ago. Sure,
there are faster motors on the market, but I question
whether most drivers have the ability to use that power
and transfer it to lap times on a track. With little to no
maintenance and good efficiency, this motor suited me.
The small overall size was another advantage to this motor.
LRP went on a diet and slimmed down the motor to work in
more conventional spaces, unlike many heavy and long
chassis designs that disrupt the balance of your car.
After the run the motor was warm, but not scorching and
the recommended gearing seemed to be pretty good. After a
short break, I put in another battery and hit the track
with the same predictable power I saw the first run.
Bravo.
Conclusion
I have worked with many new brushless motors out there,
and I found LRP's approach to design a little different
than what I see in other brands. The tuning and timing
options and construction get you to basically the same
place, but via a much more unique road. This motor has
plenty of power and hits smoothly, allowing me to focus on
driving. I like that. |
