Castle’s new proprietary Adaptive Timing System (ATS)™, released with our V5 firmware, provides a noticeable power difference right out of the box. Castle’s Adaptive Timing System™ technology and ultra-low internal resistance design maximizes efficiency and power output across the entire throttle range. The DMR 30/40 handles up to 25.2V (6S) power too. You’ll not only feel the power increase, but see longer flight times as well.

RESPONSIVE AND STABLE.

Click image to enlarge The DMR 30/40 has enhanced throttle responsiveness that translates into flights with a more agile feel, quicker response, and no sluggishness. The DMR 30/40 also sports our improved active braking algorithm ensuring that maneuvering your multi-rotor never felt so good. Combined with Castle’s exceptionally linear throttle, the DMR 30/40 delivers quick, accurate, and consistent motor response, making it simpler to dial in your PIDs.

HEAR THE RESULT!

There’s nothing like it on the market! With its proprietary algorithms and technology, the DMR 30/40 literally has a unique sound that grabs attention and gets you noticed. Our pilots have raved about the Castle V5 “turbo sound” that signals their ability to fly faster, longer, and corner with more precision.

CONVENIENCE.

Castle DMR 30/40 default settings have you ready to fly right out of the package within seconds. These convenient features include:

  • Advanced rotorSENSE2 allows elegant simplicity in throttle calibration and setting motor direction.
  • Adaptive Timing System (ATS) continuously optimizes motor timing during flight.
  • Auto-detecting input signal selects between Servo PWM, OneShot, and OneShot125.
  • Motor PWM frequency is dynamically modulated for optimum performance.

COMPACT and LIGHTWEIGHT.

Castle’s DMR 30/40 has a small footprint and a high power-to-weight ratio, a pillar of Castle’s long history of ESC designs. At a weight-conscious 5.2 grams3 this ESC delivers over 1kW, good things DO come in small packages.

RELIABILITY.

No one wants down time at the field. Don’t let its size fool you, this ESC won’t fail you mid-flight or after a “rough landing”. Castle brings a robust hardware design to the multi-rotor market that’s simply hard to find these days. Although compact and lightweight, the DMR 30/40 is designed for the harsh and unforgiving life of a multi-rotor ESC.

Coupled with our unparalleled 1-year warranty4, lifetime Tier Two "crash warranty", and world-famous technical support, Castle provides confidence and peace of mind that your DMR 30/40 ESC is a smart investment. In this day of “throw-away” electronics, put your multi-rotor investment in a trusted name with a proven track record of support and service.

FLEXIBILITY.

The DMR 30/40 has been rigorously tested with a wide range of motors commonly available on the market, giving flexibility and worry-free operation again and again. The high maximum electrical RPM allows you to run some of the fastest motors available today and at higher voltages – all the way up to 25.2V (6S LiPo).

While pre-programmed for your Multi-Rotor, the DMR 30/40 also allows access to all settings through our patented receiver wire communications5 via a Castle Link USB adapter. Additionally, the DMR delivers on the Castle promise to provide downloadable firmware updates allowing for future support and feature upgrades as they become available.

Tech Notes: 1)Please note that the response rate in this ESC is HIGH and you will need to start with lower PIDS. We suggest starting at 50% of other brands.

2)Current is specified as the maximum value the ESC can handle at full throttle for the duration of a single 4,000 mAh battery pack with the ESC in the specified speed of 25°C (77°F) or cooler airflow. Controller temperature must never exceed 100°C (212°F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESC’s operating temperature.
