I was looking at the Batshare by SmartFly and it looks like it has two inputs and two outputs. Do I have to hook up both outputs to my RX or can I just plug in the one and bundle up the other one? Alternatively, is it possible to wire one of the BatShare outputs to the RX and the other BatShare output to the ignition?
In your current plane, you say that you just run the one battery.. would you recommend this way and I'm just guessing here but are both of the universal outputs on the Hobbico LiFe batteries usuable at the same time? If so, what if I went - one LiFe output to switch to RX and the other LiFe output to switch to ignition - is that possible? Will I still need an IBEC? Although, I do like the peace of mind that two batteries give me so I think I'll still go with the BatShare route but it was just a thought..

Thanks again
