Airtronics 94780M Metal Gear, Ball Bearing, High Power Digital Servo
The Airtronics 94780M Metal Gear, Ball Bearing, High Power Digital Servo is part of the family of new generation Digital High Resolution Technology Servos from Sanwa Japan. In a case the same size as the popular analog 94358Z, the 94780M features a metal gear drive train, highest-power-in-class handling and superior speed and resolution, making this servo feel even faster because it produces full-power as soon as it moves.
Pilots and Drivers of Large Scale Aircraft and Bigger Off-Road Truggies world-wide appreciate the emense power, quality and value in this servo, making it the most popular and widely accepted servo amongst Airtronics-Team World Class Airtronics Champion Drivers and Pilots of Aircraft and Cars in the larger classes.
The Airtronics 94780M is the highest-torque servo in a standard case on the market today, and it is as fast as many other servos with much lower torque. Inside and out, this servo is built for reliability and performance. It is perfect for high-torque applications such as steering for 1:8th scale vehicles, the rudder on larger aerobatic aircraft, all control surfaces for high-power large jets and all control surfaces on 27% or larger scale planes.
Airtronics digital servos feature custom I.C.'s, Surface Mount Technology (SMT) construction and splined output shafts for easier control surface adjustments. Molded neoprene vibration isolators and injection-molded servo cases ensure superior strength and long lasting durability.
This servo features an Airtronics 'Z' connector, which is compatible with all current Airtronics receivers as well as current Hitec, JR and Futaba receivers.
*This Airtronics servo is safe to use with receivers that have a Nominal Input Voltage rating of 4.8v ~ 6.6v.

*High-power servos such as this can draw as much as 5 amps! Make sure your switch harness, servo extensions and power source (receiver battery or BEC) can meet the demands of this servo. Normal "standard" radio switch harnesses and small 500mAh batteries typically cannot supply enough current for this servo, especially when multiple servos are used.
The Advantages of Digital Servos
Digital servos offer extremely accurate and reliable centering, even in more economically priced servos.
Digital servos develop their power instantly. An analog servo develops its full power at its extreme movement. Digital servos develop their power as soon as they move, thus effectively making a digital servo stronger, even if its specifications are the same as a comparable analog servo.
Digital servos have extreme holding power. A digital servo stays in the position you command with all of its power, thus virtually eliminating the blow back found with analog servos.
Digital servos are precise. When used with a 2.4GHz digital radio, especially a fast radio such as Airtronics, digital servos more accurately translate and hold your command inputs from your transmitter. You will feel more connected to your model than when using analog servos.
Digital servos are compatible with the newest high frame rate receivers. In some cases, analog servos simply won't work with these new, high frame rate receivers.
