Hey guys, im not sure if im posting this in the right place but here we go, using this setup for a future purchase, I was wondering if i need to use a redundant battery system on this plane like the batshare from www.smart-fly.com , also, do I need a power expander for this setup ? or will the Rx be able to feed all the servos?.

Please help, new to 25% scale.
