Hitec DB951WP

RC enthusiasts, meet your new go-to powerhouse: the Hitec DB951WP. This high-speed, waterproof digital servo is engineered for anything from rugged off-road trucks and rock crawlers to giant-scale aircraft and heavy-lift helicopters. Whether you’re ripping through mud or hovering a 600-class heli, the DB951WP delivers rock-solid performance without compromise.

Blistering Speed and Torque

At 7.4 V, the DB951WP spins through 60° of rotation in just 0.10 seconds while cranking out 528 oz-in of torque. That’s enough grunt to bulldoze a heavy crawler up steep rock faces or to wrestle a short-course truck through deep ruts—all without a hint of lag. The brushless motor not only boosts efficiency and heat management but also offers a longer lifespan compared to traditional core-type designs insideunmannedsystems.com.

Rock-Solid Durability

Hitec built this servo inside a fully sealed, CNC-machined aluminum shell rated IP67. No more worrying about mud, water crossings, or aerial condensate—your servo’s guts stay bone-dry. Hardened steel gears and three precision steel pins keep the drivetrain safe from shock loads, while dual oversized bearings eliminate slop under load. In short: push hard, crash hard, and keep on running bigsquidrc.com.

Programmability & Smart Sense Analytics

Advanced 32-bit MCU technology gives you 4,096 discrete positions for feather-fine control—ideal for rock crawling’s micro-adjustments or for precise swash-plate tweaking in helicopters. Use Hitec’s free programming unit or compatible transmitter settings to dial in deadband, speed curve, and thermal cutoff. Plus, Hitec’s Smart Sense Technology can feed telemetry back to your transmitter (where supported), so you can monitor temperature and load in real time and avoid thermal stalls hitecrcd.com.

Who Should Run the DB951WP?

• Off-Road Racers & Bashers: Consistent, high-torque control in the worst conditions.

• Rock Crawlers: Ultra-slow precision and protection from water and grit.

• Giant-Scale Aircraft & Helicopters: Reliability when under heavy cyclic and collective loads.

• Robotics & Education: Programmability paired with waterproof resilience makes it a versatile actuator for research and teaching.

Installation Tips

1. Mounting: Use anti-vibration grommets to isolate chassis buzz.

2. Wiring: Route the servo leads away from receiver antennas to prevent interference.

3. Power Source: Pair with a stable 2-cell LiPo and a BEC capable of 6–7 A to avoid voltage sag.

Final Thoughts

The Hitec DB951WP isn’t for the fainthearted—it’s for the hobbyist who demands the best. Between its jaw-dropping torque, breakneck speed, and waterproof, bomb-proof housing, it stands ready to conquer the harshest RC disciplines. If you want a servo that doesn’t flinch when the going gets tough, this is your ticket.
