Holmes Hobbies SHV500 v2 Servo

(No reviews yet) Write a Review

The Holmes Hobbies SHV500 v2 servo is perfect for applications that benefit from massive torque and lightning quick speed. We particularly like it as a replacement for the stock steering servo on the Traxxas TRX-4, because it plugs right into the auxiliary power port included with the Traxxas XL-5 ESC without the need for a BEC. In fact, you can power it directly off 2S, 3S or 4S battery packs. Add in the water resistant case and whisper quiet operation, and it's no wonder why this is one of our favorite servos.

Here are the production description and specs from Holmes Hobbies:

The BLS SHV500v2 servo is designed for R/C Rock Crawlers, but at home in any vehicle that needs high torque with fast speeds. It can be powered directly from a 2s to 4s lipo battery, eliminating the need for an external BEC! Clean up your wiring, gain space in a tight rig, and enjoy silent performance from the high quality brushless motor and circuitry.

If using an ESC with a power switch, the battery must be disconnected from the ESC and servo when not in use to prevent damage to the servo and/or battery. Moly (marine) grease is recommended when lubricating the gears. Dielectric grease is recommended on the sensor board if looking to increase water resistance.
