SUNNYSKY X300A HV SBEC + Backup Cap to Spirit2

[nmsantarelli]

Good morning to all of the forum,
in the Spirit2 manual it is specified to use the two BEC outputs for models like mine which is a 700.

Checking the connectors coming out of the "SUNNYSKY X300A HV SBEC" there are two cables such as:
"Throttle/+/ -"
"RPM/+/-"

At the moment I have only connected "Throttle/+/ -".

Question:
Can the second connector "RPM/+/-" be inserted in AUX2 or do I have to isolate the yellow RPM cable and connect only "+/-" in AUX2?

I should also connect a "Backup Capacitor", in which port can I connect it?

To summarize the current connections are:
AIL pin -> SRXL2 adapter -> SPM4651T
RUD +/- -> SRXL2 adapter -> SPM4651T
AUX1 T/+/- -> Throttle from ESC
AUX2 ?/+/- -> Additional power from ESC
Ch1,2,3,4 -> Servos
Sys port -> only for interface

Thank you in advance for any help.

Regards

Manual says RPM signal on Spirit 2 goes on "PIT pin - pin in the middle of ELE/PIT/AIL port".

Connecting RPM signal to AUX2 won't do anything, won't hurt anything either. Just never connect power to ELE/PIT/AIL or SYS ports (the outer ones). Depending on receiver (if it runs off BEC power and has extra ports with a common power rail) capacitor pack can also be connected to a free receiver channel (don't think yours qualifies). Alternatively y-cable on BEC power should work.

ok thanks for the thought
