So you are saying I need the black ground wire to also go to the rx
question 1: If I do that do i also stilll have a black wire going to the ground on the lipo rx pack. i.e. the black wire from the servo splices and goes to both the rx(along with the signal) and to the lipo rx pack?
question 2: If I do connect the black ground to the rx do I run the risk of sending 7.4 volts to the rx? My original intent here is to have the rx be at 6.0v and have the servo be at lipo voltage (7.4-8.4)
This is my intent because my rx (futaba r603fs) cannot go above 6.0v
1: Yes. Everything needs to be grounded together. Use a splice-Y as mentioned, can be spliced from any of the 3 components. (you want a spliced Y ground connection, not a full loop around the 3, known as a ground loop, not good)
2. As long as you don’t connect the red positive wire from the receiver pack to the receiver you won’t complete the power circuit, thus won’t get that Voltage to your receiver. (for the same reason your servo doesn’t work now, haven’t completed the circuit)
