RESPONSIVE AND STABLE

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 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 grams 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 warranty, 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 communications 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.
