I concur. I'll use them on outer and inner engines (1 & 4 , 2 &3), if master goes, slave goes with it......2 systems. I took your advice on this about 1 1/2 years ago on a P-38 (Royal Kit) and never used due to radio synch capability with the 9CAP radio (at that time I have a 6XAS). Thank you again Bill (will purchase).
