The Cobra 5 ACE and 1721-1260kv combo is designed for 1/6th and 1/7th scale vehicles weighing up to 25lbs and up to 8s LiPo. The 1721-1260kv is a great upgrade option for the Traxxas X-Maxx and Arrma Kraton 8s. It is more powerful than the stock motors, but not crazy overpowered like our 2028 series motors. The 8mm output shaft is designed to handle the increased power of this larger motor; but does require an 8mm bore, Mod-1 pinion. It is also a great upgrade for the Arrma 1/7th scale on-road cars, IE Limitless, Infraction, Felony.
Cobra 5 ACE ESC – Co-Developed by Castle Creations, GhostRC & Perfect Pass RC
Introducing the Cobra 5 ACE—an unlimited, high-performance ESC engineered for those who live for speed runs and drag racing.

The New Standard for ESCs
This isn’t just another speed controller—it’s the ESC that everyone will be chasing. Designed from the ground up by the people who live and breathe RC performance, the Cobra 5 ACE is your unfair advantage on the road, the strip, or the track.
If you want to go faster, run harder, and leave limits behind, the Cobra 5 ACE is your next upgrade.
1721 - 1260KV
The brand new 1721-1260Kv powerful and efficient motor is designed to deliver exceptional speed, torque, and acceleration, making it the perfect choice for serious large-scale bashers who demand nothing but the best. Built with precision-machined components, high-strength magnets, and advanced winding techniques, this motor is engineered to deliver reliable and consistent performance in even the most challenging conditions.
What makes this motor different than the other 17 series motors? The 1721-1260kv is the “sane brother” to the 1721-2400kv. Where the 1721-2400kv is made for one thing, SPEED, the 1721-1260kv is built on the same platform, but at a more conventional Kv. It packs more punch and runs cooler than its baby brother the 1717-1260kv. This makes it the perfect moderate, yet powerful upgrade to the 1717 size motors that come stock in the Traxxas X- Maxx and Arrma 8s vehicles.
What ESC would you recommend? After our internal testing, we unanimously concluded that the 1721-1260Kv is an excellent companion for the Cobra 5 Ace or Mamba XLX2 and such we have already packaged the two together for purchase as a combo.
Features:
- Running modes include SmartSense™ Sensored and an ultra-efficient Sensorless mode.
- High-strength, high-temperature grade neodymium sintered magnets combined with 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.
- Our proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor.
- Updated modern and sleek design; looks as cool as it performs.
Without a robust and reliable design, efficiency will only go so far. RC enthusiasts love pushing their equipment to the edge. 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, resulting in a cooler running motor. In the end, the result is a motor with unmatched quality, performance, and reliability. We wouldn’t put our name on anything less.
