Line 17: − The idea of MICROBEAST PLUS HD is to provide a power connection that allows to connect thick power cables to the unit, so the voltage loss due to wiring and plug connection is reduced to a minimum. In general for helis with standard size servo you should always use MICROBEAST PLUS HD, because this will eleminate the "servo plug problem" as one important factor that may be critical for your power supply.<br />+ + + + +

Today's servos and especially socalled high voltage servos typically have a very high power consumption. When using Futaba BLS 451 servos for example these are very modest. Savox 1258/Align DS610 are much more demanding, one alone taking up to 15Amps peak for the instance of a second. And for very extreme example take high voltage Savox servos SB-2271SG HV. They demand up to 27Amps (1 Servo!) peak which you can see when measure the power consumption with an oscilloscope.<br />
<br />
So besides using a good stable and high rated power supply you have to ensure proper supply of the servos with this power. But when only connecting one servo plug with power leads into the receiver this may insufficient and cause a "bottle neck" in power flow. Also when the current must take a long way through the receiver, the wiring and the Microbeast, this will produce high resistance due to the connections in between and additional loss of voltage. There is no benefit if the power supply/BEC itself can deliver 20-25A when this amount of current is not able to flow to the consumers.<br />
<br />
So the idea behind MICROBEAST PLUS HD is to provide a power connection that allows for using thick power cables and directly connect these to the unit, so the voltage loss due to wiring and plug connection is reduced to a minimum. In general for helis with standard size servo you should always use MICROBEAST PLUS HD, because this will eleminate the "servo plug problem" as one important factor that may be critical for your power supply.<br />

Anyhow, it mainly depends on how you power your system. I.e. when using an ESC with only one bec line (and if this works without issues), then there will no benefit of using the HD version as you already have a "bottle neck" at the power output. The small wire will not be able to transfer more than 5 Amps continous current. Connecting this little wire to MICROBEAST's HD input will not help very much here.<br />
