The 1207TG is a premium servo from Power HD with a standard-size footprint but a very low height, resulting in a unique low profile that reduces weight and allows use in applications with tight space constraints.

The HD-1207TG is a premium servo that is set apart by its unique, low-profile shape. Despite its reduced size and weight, the 1207TG offers the kind of performance usually only found in heavier standard-size servos, which makes it great for applications with tight space or weight constraints. The picture on the right shows how the 1207TG compares to our popular 1501MG standard-size servo.
Digital electronics combined with a coreless motor, titanium-shielded aluminium gears, and two ball bearings give this servo a distinct edge over typical standard-size servos. The 1207TG works with standard RC pulses at frequencies up to 333 Hz. The 12″ (300 mm) lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. The picture below shows an example of the hardware that might be included with this servo (hardware might vary).

Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.

Most standard radio control servos (and all RC servos we sell) have three wires, each a different colour. Usually, they are either black, red, and white, or they are brown, red, and orange/yellow:
Please check the specs for your servo to determine the proper power supply voltage, and please take care to plug the servo into your device in the proper orientation (plugging it in backwards could break the servo or your device).
We do not specify the range of rotation of our servos because this information is not generally available from servo manufacturers. RC servos are usually intended for controlling things like the steering mechanism in an RC car or the flaps on an RC plane. Manufacturers make sure that the range is enough for these typical applications, but they do not guarantee performance over a wider range.
This means most RC servos will rotate about 90° using the standard 1–2 ms pulse range used by most RC receivers. However, if you are using a controller capable of sending a wider range of pulses, many servos can rotate through almost 180°.
You can find a servo’s limits if you use a servo controller that can send pulses outside of the standard range (such as our Maestro servo controllers). To find the limits, use the lowest possible supply voltage at which the servo moves, and gradually increase or decrease the pulse width until the servo does not move any further or you hear the servo straining. Once the limit is reached, immediately move away from it to avoid damaging the servo, and configure your controller to never go past the limit.
You might be wondering why we do not just follow the above steps for all the servos we carry and list a specification for degrees of rotation. Unfortunately, since servo manufacturers do not specify the range of rotation, it might change from one manufacturing run to the next. They will not inform us about changes that are not specified, and we have no way of knowing if or when they might change their manufacturing process.
