This simple lightweight device will double the throw of a servo, from 90 to 180 degrees.
MOST (but not all) servos are capable of 180-degree travel - but this can only be achieved through using this device - or by using a high-end programmable computer radio (Radiomaster, etc).
Servos that are advertised as a 180-degree servo (for example, the SG90 9-gm servo) will only move 90 degrees with a standard RC transmitter.
Signal increase: The original signal the receiver sends to the servo is 1000-2000us which provides a 90-degree throw. This device expands the range to 500-2500us to give a 180-degree throw.
SPECIFICATIONS: PPM/PWM signal amplifier - 180-degree servo extender
Applicable voltage: 3.6-6v
Weight: 3.7g
Device Size: 15.3 x 10.5 x 3.0 mm
Total wire length: 9 inches
IMPORTANT NOTE: After installing the signal amplifier, it is necessary to test the operation to determine whether the device will cause the servo motor to exceed its operating limits! To avoid stalling and burning out the servo motor you may need to adjust the end points using your radio transmitter settings. This device may cause the servo to "jump or "stutter" - if that happens then lower the servo's speed setting using your radio TX or use a speed reducer.
