Hi Bobby and Scott,

You guys probably now the most common reasons a plane crashes besides our dumb thumbs is because of switch and battery failing. There are switches on the market that fail in the on position only so that takes out the switch problem. Using two batteries allows the amp load to be split between them. JR type plugs that most of use are only good for about 3 amps. I would be willing to bet that your plane pulls that much during some high control deflection maneuvers. My vote is with two batteries and deans plugs (if able) on 33% planes and larger. That’s my 2 cents LOL.
