Presenting the Hitec HS-65HB, one of the the best micro servo's available with Karbonite Gears. So what's so special about this servo? Well how about 31 ounces/inch of torque and 0.11 sec speeds at 6 volts in a compact 23.60 x 11.60 x 24.00mm footprint, Super Strong Karbonite Gears capable of cycles in excess of 300,000 with Zero Wear and almost five times the strength of nylon gears, Top Ball Bearing for smooth and quiet operation, versatile enough for small and large applications, and best of all it's extremely easy to modify for continuous rotation. This is one servo Futaba, GWS and JR can't touch. A micro monster with whopping torque/speed and if you can afford the $21.00 price then you can't go wrong for the quality/durability you get with this fine product. So why bother with extra torque in a compact unit and not just get a cheap servo instead? Well let me give you an example. Torque complements speed and let's say you have a mobile robotic platform using cheap micro servos for drive. As you begin to add weight (eg. batteries, sensors, controllers) your platform begins to suffer and the speed is heavily decreased, not to mention the excess strain on those weak nylon gears. Having that extra torque output and the Karbonite gears gives you an advantage, the boost your platform needs to counter the effects of weight and keep it moving. This servo gets it done and does a fine job in its modified continuous rotation form. So how easy is it to modify? So easy that you only need to touch one gear. That's Right! No extracting of PCB boards, replacing of potentiometers with resistor networks or even cutting a single wire. Don't even mess with the electronics and save your servos in case you want to return to standard servo performance (see step 7). Why the steps are so easy you could just follow the photos. But please do read for "reading is knowledge" and well worth it. With that said, let's begin....................
