I have searched but didn't find the answer.
if I set up a single battery in my plane directly to a Y cable and then power my rx from one lead and the spark switch battery connection from one lead, will that be a bad connection prone to interference?
the signal wire goes from the rx to the rx-port on the spark switch ofc.
will the ground interference stop at the battery Y-cable or spread back into the receiver?
(I have found questions regarding connecting the spark switch to the rx for power and I understand why that is a bad thing)
And IF its a bad thing, what's the solution to running only one battery?
RX: Spektrum 8360T
battery: 4000mAh 2s lipo
Engine: Stinger 40cc twin
Bonus question: if I want the RPM lead from the ignition module back to my rx, is a solution buying the spark witch pro? can that monitor both heat and rpm and send it back to my spektrum rx?
Happy winter times to all!
