For more than two-decades Castle motors have powered record-breaking performance.
Now that expertise drives something entirely new: next generation sensored control built for serious R/C.
Engineered for Efficiency
Our improved 4-pole, 12-slot architecture runs cooler and delivers uncompromising power, lap after lap.
QUIETSENSE™ Precision
Exclusive sensor shielding and Flux Shield™ with secondary sense magnets keep your motor and ESC locked in perfect sync for ultra-smooth launches and immediate throttle response.
Smart by Design
Forget manual timing tweaks. Advanced sensor alignment delivers uniform torque in both directions—automatically.
Built for the Long Run
A fully rebuildable design makes maintenance fast and cost-effective. And a modern, streamlined exterior looks as advanced as the technology inside.
The Future of Brushless Power
This is more than a motor. It’s Castle innovation—refined into pure, precise motion.
08 Series Brushless Sensorless Motors
Our 4 pole 0808 series motors are intended for on-road and off-road applications running up to 3S LiPo and weighing in at up to 2.5lbs. 0808 motors are available with in combos with both of our race-proven Micro ESCs. For 2WD and lighter 4WD vehicles (<1.5lbs) we recommend the Sidewinder Micro 2, and for heavier 4WD vehicles (>1.5lbs) the Mamba Micro X is recommended. The 0808 series motors deliver tremendous performance for an extremely affordable price.
Not intended for 1/16th scale or 1/14th scale vehicles (IE Losi Mini-8ight/T, Traxxas Mini E-Revo)
10 Series Brushless Sensored Motors
Featuring the same long-life, high-quality components as our 14, 15, 17 and 20 SERIES 4-pole sensored motor designs, these 28MM MOTORS are optimized for power and efficiency in 1:14 and 1:16 vehicles.
14 Series Brushless Sensored Motors
The 4 pole 14xx Series sensored motors are our most versatile motor design. From the super low Kv needs of Crawlers to the super high Kv needs of Race Buggies, we have a 14xx motor for you. 14xx motors can handle 2-3S LiPo in 1:10th Scale 2WD SCT Trucks up to 5lbs, stadium trucks, buggies, and on-road vehicles up to 4lbs.
14 Series Brushless Sensored 2s No Prep
Castle’s 4-pole 6400KV motor for no prep drag racing is the undisputed KING OF THE STREETS! Castle was the first mainstream manufacturer of 4-pole brushless motors for the hobby, and we leveraged our decades of motor design and manufacturing experience to create the most powerful motor to ever hit the drag strip. Our Street Eliminator design is distinct from the competition with big block American muscle which offers more horsepower and torque for higher speed and lower ETs.
14 Series Crawler Edition Motors
Our latest additions are the 1406 series in a "SLATE" color, in 1900KV, 2280KV, 2850KV and 3800KV. These motors are ROCK READY and we have the startup on low RPMs under control. Castle now has you covered if you are looking for ultimate control out on the trails or on your Ultra 4 track days.
If you're looking for a higher torque motor for rock racing, hill climbing or hardcore trail running you will want to use the larger, higher torque and power rated 1410 - 3800kv motor.
15 Series Brushless Sensored Motors
Available in 1650Kv, 1800kv, 2200kv, and 2650kv variants, our 15 series motors are ideal for 1:8 scale off-road and on-road vehicles as well as 1:10 scale 4WD SCT up to 9lbs.
17 Series Brushless Sensored Motors
Available in 1650Kv. It is the perfect upgrade for any 1/6th scale vehicles weighing up to 20 lbs and running up to 8s LiPo; it is also a great upgrade for drivers looking for a reliable, high torque 8s motor for their 1/8th scale vehicles.
17 Series EXTREME Brushless Sensored Motors
The 1721-2400Kv mechanical design boasts a stainless-steel sleeve to reinforce and strengthen the rotor for high RPM operation. Coupled with a massive 8mm stainless steel motor shaft, 8.0mm bullets and high strand, low resistance, silicone coated 8-gauge copper wire, it delivers massive power and maximum top end speed. It is intended for use in 1:8 and 1:7 scale vehicles up to 8s LiPo, and the perfect compliment to the Castle Mamba XLX2 ESC.
20 Series Brushless Sensored Motors
The Castle 2028 Extreme motors have an IMPROVED 4-POLE 12-SLOT design that boasts exceptional EFFICIENCY and produces LESS HEAT. If you need LARGE-SCALE POWER for LARGE-SCALE VEHICLES the BRUSHLESS SENSORED 2028 series motors will no doubt hold up to the heavy throttle and extended usage that 1/5th scale vehicles like the Losi 5IVE-T, 5IVE-B or DBXL-E encounter. These are the perfect upgrades for any 1:5 scale RC hobby vehicles (including gas to electric conversions) weighing up to 30 lbs for 2WD and 25 lbs. for 4WD. The 2028 Extreme can easily run in the 10 horsepower range*
*Burst power output for durations typical of vehicle acceleration
25 Series Brushless Sensored Motors
The 25 Series Motors are the largest and most powerful motors ever produced by Castle. Designed to produce the torque and power for vehicles weighing up to 50lbs and up to 12s LiPo. When paired with the Castle Cobra 5 HV, the 2535 - 520kv can easily push 1/5th and 1/4th vehicles like the Losi 5IVE-T, 5IVE-B, or DBXL-E. It is the perfect upgrade for any 1:5 and 1:4 scale RC hobby vehicles (including gas to electric conversions).
