6203SB High Speed and High Voltage

[Jamesppp]

I have recently been using these Rx's as satellites on Skookum 720's and the new 540 FBL controllers.
The 720 requires an adapter cable which supplies approx 3.2v.This adapter cable is the only wire connected to the Rx. No servos powered from it at all.
On my Logo 500 low voltage system, for good measure used a power only jumper cable from the FBL controller to the S bus Rx to supply 5.2v. I'm not sure if this is needed but it is there and works fine

On my current build, a high voltage setup on a Compass 7HV, will it be all right to add the power only jumper? This system is powered by a 2S lipo. I set the Rx to HV as best as I can tell but there is no voltage regulator.
Is the jumper necessary ? I measured 3.2 v on the adapter cable which is very close to the minimum required for the Rx but I don't know if the Rx can ever draw any additional load as there are no servos connected to it(them)

Sorry for the long post

Thanks

First thing is that the R6203SB is not a "satellite" it IS the receiver.

Second, you do not "set" the receiver to HV, it simply is rated for high voltage, there is nothing to do in that regard.

I do not know anything about the Skookum unit so I am not clear why it only passes 3.2 volts to the RX. I use the same RX with a CGY-750 and I ran a power lead from a separate RX/servo battery pack into both the RX and the FBL unit. I also plug the ESC (with red wire clipped) directly into the RX. This way even if the FBL goes crazy I can at least kill power to the motor.

The RX generally is good down to just under 3.0 volts, and with no lod on it except its own power requirement the 3.2 volts should be OK.
