Gday Guys/Gals , My Name is Andrew and have been flying glow Planes for over 25 yrs, just recently began getting back into it after w a few years off so decided to purchase a new model of a club member from miles and miles away my only problem is that its a gasoline engine and i have no idea on how to connect the thing to my radio as the previous owner used only the one battery to power the spark and receiver , now im getting told by others that , thats a bad idea , so ok i need two batteries that should be simple enough, but for me its became a struggle as no longer a spring chicken and dont handle pressure and new tech too well, so if someone could give us the run down on how to connect two battery packs one for receiver and one for the spark would be so gratefully appreciated my engine is the evolution 10 GXE With pumped Carb,

where do i plug in the spark batt and what type should i use basically how do i have two packs running at the same time one for spark and one for receiver do i plug batt for spark to engine and alocate a switch on radio to turn on and off and do i plug the normal 6v pack into the batt section of receiver and so on please help lol !!
