Hi,
I am in the middle of my first gas airplane setup. now i am consider the following options :

1) IBEC + dual batteries and switchs. ( currently i am using dual nicd batteries and switchs on my glow airplanes )
2) Dual batteries for rx + separate battery for ignition + Remote Kill Switch

the IBEC connects to the rx through fiber optic cable but some pepole says that there is still good chance of RFI interferences.

what about remote kill switch ? it's also connects to the rx through fiber optic cable is that means it will also have the same chance of RFI interferences ?

Thanks
