Re: Legality - Splitting PWM cables for servo motors

Hotwings,
In the past the RC controller manual allowed a "y" cord to establish a PWM signal to be split to two speed controllers. Since Eric has pointed out the DSC is current limiited to 15 ma, I would not suggest you split a PWM signal on this year's control system. You run the risk of over current on a single PWM output with two opto couplers so connected. Also as Eric pointed out, the jumper to allow power to a servos is limited to 3 amps. You will need to determine the current rating on each servo type you will be using and make sure your design would remain below the three amps.
