Just bought a new yak 74 from EF,going to put an OS 160 fx on it,probably will use a slmline pitts on it,since it has 2 fittings.Was thinking of using the showtime smoke system since it has its own battery that you can charge and doesnt pull off of receiver battery,what size tank should i run,need some help ,never done smoke before,any other suggestions would be nice too!!!
