We have recently revamped our line of Servo Power Gearboxes! Our gearboxes have always been top-of-the-line and super powerful (up to 3,402 oz-in of torque!) but now offer upgraded features and a more durable construction.

For starters, all of the servo power gearboxes that use an external potentiometer are now digital rather than analog. Digital servos provide more torque, higher precision, faster response times and are fully programmable. The programmable features allow the user to tailor the servo to perfectly fit various applications.

The decision between NiCAD and NiMH batteries can be confusing. Choosing the correct battery for your application is critical. When making this decision you may need to ask yourself the following questions:
1. How much room do I have?
2. How much weight can my application handle?
3. How many amps will I be using under full load?
4. How much “run-time” do I need?
5. How fast do I need to recharge?


NiCAD (Nickel-Cadmium) and NiMH (Nickel-Metal Hydride) are two very different types of batteries. Both types must be handled differently from one another in regards to charging and discharging procedures and philosophies.

In general, NiMH batteries cannot handle the high rate of charges or discharges (typically over 1.5-2 amps) that NiCAD batteries can. Many modelers use high rate, peak detection or time-based chargers to charge NiCAD batteries. Such chargers are NOT recommended for NiMH batteries (unless otherwise specified in the charger or battery literature) as they can cause permanent damage to the NiMH cells. Also, NiMH batteries will not perform well in high rate discharge applications, typically providing only a small fraction of the rated capacity in these instances.

NiMH batteries also have approximately twice the self-discharge rate of NiCAD batteries when in an unused state. For example, when your radio is off, a 1650mah NiMH battery can discharge itself nearly twice as quickly as a NiCAD battery, typically within one week. Therefore, you must charge...Continue Reading
