Product Features- Superior strength and power in a standard size servo
- Brass and hardened steel counter gears
- Hard anodized aluminum output gear
The 2721 features the same powerful coreless motor and proven reliable amplifier as the 4721, but with a significantly strengthened gear train. It has a hard anodized aluminum output gear and brass and hardened steel counter gears. The output gear is hard coated aluminum, so it's lightweight, and the hard-coated surfaces are incredibly tough and resistant to wear. The gear train is also narrower, allowing for a shorter top case, making the overall height of the 2721 3/16" shorter than the 4721. All other case and mounting dimensions are identical to the 4721 and will directly replace any standard size JR servo (507, 517, 531, 4131, 4735, or 4721).
For high stress, high power applications such as giant scale aircraft, large scale racers, etc, JR's metal-geared 2721 servo offers the ultimate in strength and power in a standard size servo.
