The DX7 Microlite system includes the feather-light, 3.5-gram AR6100 Microlite Receiver and three DS285 Digital Sub-Micro Servos. In addition to being the lightest receiver in its class, the AR6100 can be operated with a wide range of input voltage (3.5V – 9V). And the digitally precise DS285 servos offer more than enough speed and torque for any small electric application.
