#XP-WR-4401 - Xpert RC WR-4401 Brushlesss Waterproof Servo 21.45kg 0.077 60deg@6.6v. 4.8-6.6v

Xpert now bring to market the "WR" Water Resistant Spec servos. These are based on the architecture of the ever popular SN Series but with added water resistance and still maintaining the aluminium center case and gear support.

Xpert Servos are a range of high spec servos, ALL of which are brushless for reduced current draw, increased efficiency and reduced running temperatures.

Xpert RC have been developing this range for some time now and have been carrying out extended durability testing and performance testing is some of the toughest fields in the market including 1/8thBuggy and Truggy as well as some very large high demand flight units.

Xpert have taken a quality first approach with the entire range and focus on high performance.

The quality of these servos has stunned us, featuring very precise PCB production and use of only the highest quality components. The quality is apparent as soon as the servo is first seen but becomes even more apparent when used exhibiting extreme accuracy and position holding.

SN Range.

All SN Series servos all feature brushless motors and 4096 steps of resolution giving ultra precise control and low current draw.

The SN Series servos feature a machined inner and outer middle case which locates directly on the brushless motor to provide cooling, increasing efficiency and strength. With the inner upper part also having been machined this adds additional cooling and provides a very sturdy foundation for the drive train supports. Also features O Ring seals between case sections and even on the retaining screws.

• Brushless motor design provides extremely high speed, top efficiency, and low power consumption.
• 4096 resolution and SIC (Single Integrated Circuit) for the highest performance and durability.
• Light weight design
• Aluminum middle case for optimized thermal dissipation.
• Strong Metal Gear
• Glitch-free
• Sophisticated error correction
• High-Speed, High-precision 12-bit AD converter and CPU calculation
• Fail safe
• Over current protection
• Over temperature protection

All Xpert RC Servos will come with a 12month warranty, which is an exchange warranty rather than repair. NB This does not cover water damage or incorrect set up of the servo such as EPA settings / servo stalling.
