Yes. All of the receiver channel inputs have an internal pull-down resistor, which keeps them stable when left unconnected. ... more

There is no substitute for testing; if in doubt, do the experiment. It depends on how much current they draw, and how large a margin of safety you want. A design that attempts to cater for the simultaneous stalling of all servos will be so heavy ... more

No. The outputs are fixed at 5 volts for the receiver and 6 volts for the servos. You must ensure that your servos are rated for 6 volt operation, and if not, either don't use a ServoStation, or if the total current drawn from the 5 volt supply will ... more

Yes, the ServoStation was designed with UAVs in mind. The ServoStation is specified to operate over the full industrial temperature range (-40 to +85°C). Stabilised aircraft place a heavy and continuous burden on their power supplies because of the ... more

In the absence of a valid transmitter signal, PPM (Pulse Position Modulation) receivers will decode background RF noise into full amplitude digital nonsense, and mindlessly output this to the servos. The servos will attempt to comply with these ... more

Not deliberately, no, but like most electronic devices if the supply voltage goes low enough, it will stop working (see above). Low voltage cutouts exist to prevent batteries from becoming too depleted. This is important because some types of ... more

Servos are faster and have higher torque at 6 volts, which is important for extreme manoeuvres. Helis in particular, benefit from the improved servo performance possible at 6 volts. Running the receiver from a completely separate and slightly lower ... more

A BEC is a Battery Eliminator Circuit. RC vehicles typically need 5 volts to power their radio receiver and servos. Unfortunately electric motors usually require batteries that have a much higher voltage than this. A BEC solves this problem by ... more
