Brushless motors are pretty much the standard in electric cars these days, and LRP has been making their own versions since day one. Now with their latest offering, LRP is ready to take on the competition with smooth power, easy adjustments, low maintenance, and user-friendly design. Making its first international racing debut at the recent 2008 IFMAR Electric Worlds in Thailand, and sporting a few very unique features, the LRP Vector X12 6.5T BL motor is now available to the public.

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.

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.
