Building a Bud Nosen 310 and putting gas engines on it. Do i need to put separate battery's in for each engine and also opt kill switches ?
Thanks

Those planes are so big Having a battery out at each motor for ignition makes sense. Also the kill switch is never a bad idea.. just lay it out clean.. You have plenty of room to work with.

A modern setup would have 2 ignition battery eliminators connected to the same channel on the RX. you could locate them in the nacelles or in the fuselage, it wouldn’t make much difference. Run dual batteries into the RX of about 3000 mah. Everything gets powered off the same two batteries.
