Thermal performance and power handling are two of the most important aspects of any motor design. We wouldn’t put our name on anything less.Ībility to withstand the harsh demands of any RC application In the end, the result is a motor with unmatched quality, performance, and reliability. Construction of our motor required careful component selection each verified through internal testing to ensure the highest efficiency possible. Our proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor. High-strength, high-temperature grade neodymium sintered magnets combined with a high-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions. Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible. The Castle engineers know this and spared no expense when developing a design that could hold up to the harsh conditions that the RC community will throw at it. RC enthusiasts love pushing their equipment to the edge. Without a robust and reliable design, efficiency will only go so far. You can run it longer (with the same battery)

The higher the efficiency of the motor, the less energy it turns into heat keeping it cool under extreme loads. The higher the efficiency of a motor, the less power it takes to produce the same output power, which allows you to run longer on a single charge. The higher the efficiency of a motor the more power it can produce without overheating, which allows you to safely run higher gear ratios.

Be careful, this motor is known for insane burnouts, backflips and jumping buildings! WHAT MAKES AN EXCEPTIONAL MOTOR? The biggest of them all is the 2028 which is our only 20 series motor made for giant 1:5th scale buggies and monster trucks. 15 series motors are perfect for 1:8th scale buggies, truggies and monster trucks. We have two 15 series lengths - 15 the longest of the two. 1:10th scale vehicles vary greatly in size and weight so pay close attention to the specs provided by both castle and the vehicle manufacturer. A 1415 is our longest 14 series while the 1406 is our shortest with the 1410 landing right in the middle. The longer the motor, the more torque it has. Our 14 series motors are offered in the widest range of rpm and motor length for 1:10th scale vehicles. Our 08 series motors are great for small 1:18th scale buggies, trucks and on road cars. The size of motor you choose will depend upon the size of your vehicle, the drivetrain (2wd/4wd) and how much it weighs. Castle offers 4 different motor size families for a wide range of vehicle scale applications. The first two digits in our motor names refer to the diameter of the stator in inches, while the second two digits refer to the stator length.
