The Chief Racing Motor was developed by Lumenier in collaboration with professional drone racing pilot Alex “Chief” Campbell. Chief had asked us to make a motor that would give him an edge on the racetrack, but also in the pits, where many pilots often spend time repairing broken gear.

What’s A Racing Motor Anyway?

Race Pilots put their drones under extreme stress. The constant high throttle environment can really push the components to the limit, namely motors. When a motor is pushed too hard the enamel on the windings can deteriorate and cause shorts, burning up your motor ending your lap in an instant. With the Chief Motor, Lumenier set out to make burnt motors a thing of the past. Most motors use windings rated up to 180C°, but the Chief motor is constructed with enamel capable of withstanding over 240C°! If Chief can’t burn ’em up, there is a pretty good chance you can’t either.

Another obvious factor in racing is power, and the Chief Racing Motor has plenty of that. With a minuscule air gap between the stator and curved N52SH bell magnets, you get great efficiency and power. And since the windings can take abuse, you can feel confident running high voltages, even up to 6S on these puppies, which feels pretty close to Mach 1.

Built To Last

The Chief is the first motor by Lumenier to employ titanium alloy shafts. These shafts are made from high-quality titanium alloy to help save weight, while also strengthing the overall shaft and prevent the threads from stripping.

The motor features a minimal lightweight base and hollow steel 4mm shaft with screw termination for easy maintenance. Every gram counts in racing, so we made the Chief 2207 motors as light as we could (29g) without sacrificing durability or power.

Carefully assembled and dynamically balanced to the highest standard in Lumenier’s climate-controlled facility, the Lumenier Chief motors deploy state of the art glue technology, application robots for even glue distribution, and advanced curing procedures to ensure magnets won’t slip — even under the tremendous demands put on them during drone racing and FPV freestyle events.
