3 Mode - Servo / ESC Tester (3CH 4-8-6V)

This device bypasses the need to use radio equipment when testing your motors or servos. It's a signal generator which can drive your speed controllers (ESC), and therefore enable you to control your motors. It supports up to 3 channels (i.e. it can drive up to 3 ESCs or up to 3 Servos). 

Three modes:

• Manual mode: Use to manually control motor RPM or servo position  from 0 - 100%.
• Neutral mode: Moves servos to the neutral position.
• Automatic "window wiper" mode: Makes the servo swing from their minimum to maximum extents.
